What is Arc Flash? https://phasorcorp.com/arc-flash/ https://phasorcorp.com/arc-flash/#respond Mon, 14 Jul 2014 19:51:21 +0000 http://phasorcorp.com/?p=714

Understanding “Arc Flash”

Simply put, an arc flash is a phenomenon where a flash over of electric current leaves its intended path and travels through the air from one conductor to another, or to ground. The results are often violent and when a human is in close proximity to the arc flash, serious injury and even death can occur.
Arc flash can be caused by many things including:
– Dust

  – Dropping tools

– Accidental touching

– Condensation

– Material failure

– Corrosion

– Faulty Installation
Three factors determine the severity of an arc flash injury:
1. Proximity of the worker to the hazard

2. Temperature

3. Time for circuit to break
Because of the violent nature of an arc flash exposure when an employee is injured, the injury is serious – even resulting in death. It’s not uncommon for an injured employee to never regain their past quality of life. Extended medical care is often required.
Typical Results from an Arc Flash:
– Burns (Non FR clothing can burn onto skin)

– Fire (could spread rapidly through building)

– Flying objects (often molten metal)

– Blast pressure (upwards of 2,000 lbs. / sq.ft)

– Sound Blast (noise can reach 140 dB – loud as a gun)

– Heat (upwards of 35,000 degrees F)

The four types of electric arcs:

1.Open air arc – The primary arc used in arc testing
2.Arc-in-a-box – Used in one form for arc testing in the EU
3.Ejected Arc – When arc plasma hits the worker
4.A tracking arc – Most common at higher voltages, arc plasma conducts on skin or through clothing

Only the first two are considered in the calculations and standards. The open air arc is well understood.

In lab testing, we control movement of the arc for the sake of repeatability, but in real life from 480V higher the open air arc can quickly turn into an ejected arc or a tracking arc. The tracking arc is most common at very high voltages or during an electrical contact.

The Importance of a UPS Battery Backup Device https://phasorcorp.com/importance-ups-battery-backup-device/ https://phasorcorp.com/importance-ups-battery-backup-device/#respond Fri, 11 Jul 2014 13:50:17 +0000 http://phasorcorp.com/?p=712 The Importance of a UPS Battery Backup Device

UPS stands for uninterruptible power supply or uninterruptible power source. This is an electrical device meant to provide power supply to a load in the case of a power outage or when the power input fails.  It differs from an auxiliary or emergency power system or standby generator in that a UPS device provides instantaneous (or very nearly instantaneous) protection from power outages.

At any moment and for any reason, power supply could be suddenly cut off.  Power outage can result from electrical poles being damaged by storms or traffic accidents.  Faults in the grid or power plant can also cause blackouts.  Or there simply may not be enough power supply in a particular area at that time, so power outages are scheduled.  We have learned to cope with these inconveniences but our computers, unfortunately, just are not hardwired to cope with them in the same way.

Sudden power loss during data transfers can damage partitions making the hard drive inaccessible.

Computers are fragile pieces of machinery which can be damaged by a sudden power outage or fluctuation.  Items in a computer like hard drives can be affected and data can even get lost when power goes off and you have not properly shut down your computer.

It is especially damaging to the computer hard drive when there is  power interruption.  When power is suddenly cut off, your hard drive spins down without being shut down properly.  When power comes back, and you restart, at times you may find that much of your work has been lost. Sudden power loss during data transfers can damage partitions making the hard drive inaccessible. Also power comebacks usually are accompanied by flickers or fluctuations which may turn your computer off again.  Hard drives can only take too much of this type of abuse.  There are some cases where computers even blow up.

To protect your computer hard drive from these unfortunate scenarios, you need to plug your computer into an electrical device called a UPS system.  Right at the moment of a power blackout, these nifty devices will act as a battery backup power supply which will automatically provide power to your computer for long  enough to allow you to save your data and properly shut down your computer.

A UPS device not only protects your computer from lack of power, it also protects from too much of it.  A UPS is also a surge protector in that it shields your computer from those little brownouts or flickers which we do not notice but which can wreak havoc on your computer.

By Geoffrey H. Wold

The continued operations of an organization depend on management’s awareness of potential disasters, their ability to develop a plan to minimize disruptions of critical functions and the capability to recovery operations expediently and successfully. A disaster recovery plan is a comprehensive statement of consistent actions to be taken before, during and after a disaster. The plan should be documented and tested to ensure the continuity of operations and availability of critical resources in the event of a disaster. The primary objective of disaster recovery planning is to protect the organization in the event that all or part of its operations and/or computer services are rendered unusable. Preparedness is the key. The planning process should minimize the disruption of operations and ensure some level of organizational stability and an orderly recovery after a disaster. Other objectives of disaster recovery planning include:

• Providing a sense of security

• Minimizing risk of delays

• Guaranteeing the reliability of standby systems

• Providing a standard for testing the plan.

• Minimizing decision-making during a disaster

The three-part diagram illustrates the planning process. The methodology is described below.

1. Obtain Top Management Commitment Top management must support and be involved in the development of the disaster recovery planning process. Management should be responsible for coordinating the disaster recovery plan and ensuring its effectiveness within the organization. Adequate time and resources must be committed to the development of an effective plan. Resources could include both financial considerations and the effort of all personnel involved.

2. Establish a planning committee A planning committee should be appointed to oversee the development and implementation of the plan. The planning committee should include representatives from all functional areas of the organization. Key committee members should include the operations manager and the data processing manager. The committee also should define the scope of the plan.

3. Perform a risk assessment The planning committee should prepare a risk analysis and business impact analysis that includes a range of possible disasters, including natural, technical and human threats. Each functional area of the organization should be analyzed to determine the potential consequence and impact associated with several disaster scenarios. The risk assessment process should also evaluate the safety of critical documents and vital records. Traditionally, fire has posed the greatest threat to an organization. Intentional human destruction, however, should also be considered. The plan should provide for the “worst case” situation: destruction of the main building. It is important to assess the impacts and consequences resulting from loss of information and services. The planning committee should also analyze the costs related to minimizing the potential exposures.

4. Establish priorities for processing and operations The critical needs of each department within the organization should be carefully evaluated in such areas as: • Functional operations • Key personnel • Information • Processing Systems • Service • Documentation • Vital records • Policies and procedures Processing and operations should be analyzed to determine the maximum amount of time that the department and organization can operate without each critical system. Critical needs are defined as the necessary procedures and equipment required to continue operations should a department, computer center, main facility or a combination of these be destroyed or become inaccessible. A method of determining the critical needs of a department is to document all the functions performed by each department. Once the primary functions have been identified, the operations and processes should be ranked in order of priority: Essential, important and non-essential.

5. Determine Recovery Strategies The most practical alternatives for processing in case of a disaster should be researched and evaluated. It is important to consider all aspects of the organization such as:

• Facilities • Hardware • Software • Communications • Data files

• Customer services • User operations • MIS • End-user systems

• Other processing operations Alternatives, dependent upon the evaluation of the computer function, may include:

• Hot sites • Warm sites • Cold sites • Reciprocal agreements

• Two data centers • Multiple computers • Service centers

• Consortium arrangement • Vendor supplied equipment

• Combinations of the above Written agreements for the specific recovery alternatives selected should be prepared, including the following special considerations:

• Contract duration • Termination conditions • Testing • Costs

• Special security procedures • Notification of systems changes

• Hours of operation • Specific hardware and other equipment required for processing

• Personnel requirements • Circumstances constituting an emergency

• Process to negotiate extension of service • Guarantee of compatibility

• Availability • Non-mainframe resource requirements • Priorities • Other contractual issues

6. Perform Data Collection Recommended data gathering materials and documentation includes: • Backup position listing • Critical telephone numbers • Communications Inventory • Distribution register • Documentation inventory • Equipment inventory • Forms inventory • Insurance Policy inventory • Main computer hardware inventory • Master call list • Master vendor list • Microcomputer hardware and software inventory • Notification checklist • Office supply inventory • Off-site storage location inventory • Software and data files backup/retention schedules • Telephone inventory • Temporary location specifications • Other materials and documentation It is extremely helpful to develop pre-formatted forms to facilitate the data gathering process.

7. Organize and document a written plan An outline of the plan’s contents should be prepared to guide the development of the detailed procedures. Top management should review and approve the proposed plan. The outline can ultimately be used for the table of contents after final revision. Other benefits of this approach are that it: • Helps to organize the detailed procedures • Identifies all major steps before the writing begins • Identifies redundant procedures that only need to be written once. • Provides a road map for developing the procedures A standard format should be developed to facilitate the writing of detailed procedures and the documentation of other information to be included in the plan. This will help ensure that the disaster plan follows a consistent format and allows for ongoing maintenance of the plan. Standardization is especially important if more than one person is involved in writing the procedures. The plan should be thoroughly developed, including all detailed procedures to be used before, during and after a disaster. It may not be practical to develop detailed procedures until backup alternatives have been defined. The procedures should include methods for maintaining and updating the plan to reflect any significant internal, external or systems changes. The procedures should allow for a regular review of the plan by key personnel within the organization. The disaster recovery plan should be structured using a team approach. Specific responsibilities should be assigned to the appropriate team for each functional area of the company. There should be teams responsible for administrative functions, facilities, logistics, user support, computer backup, restoration and other important areas in the organization. The structure of the contingency organization may not be the same as the existing organization chart. The contingency organization is usually structures with teams responsible for major functional areas such as: • Administrative functions • Facilities • Logistics • User support • Computer backup • Restoration • Other important areas The management team is especially important because it coordinates the recovery process. The team should assess the disaster, activate the recovery plan, and contact team managers. The management team also oversees, documents and monitors the recovery process. Management team members should be the final decision-makers in setting priorities, policies and procedures. Each team has specific responsibilities that must be completed to ensure successful execution of the plan. The teams should have an assigned manager and an alternate in case the team manager is not available. Other team members should also have specific assignments where possible.

8. Develop testing criteria and procedures It is essential that the plan be thoroughly tested and evaluated on a regular basis (at least annually). Procedures to test the plan should be documented. The tests will provide the organization with the assurance that all necessary steps are included in the plan. Other reasons for testing include: • Determining the feasibility and compatibility of backup facilities and procedures • Identifying areas in the plan that need modification • Providing training to the team managers and team members • Demonstrating the ability of the organization to recover • Providing motivation for maintaining and updating the disaster recovery plan

9. Test the Plan After testing procedures have been completed, an initial test of the plan should be performed by conducting a structured walk-through test. The test will provide additional information regarding any further steps that may need to be included, changes in procedures that are not effective, and other appropriate adjustments. The plan should be updated to correct any problems identified during the test. Initially, testing of the plan should be done in sections and after normal business hours to minimize disruptions to the overall operations of the organization. Types of tests include: • Checklist tests • Simulation tests • Parallel tests • Full interruption tests

10. Approve the plan Once the disaster recovery plan has been written and tested, the plan should be approved by top management. It is top management’s ultimate responsibility that the organization has a documented and tested plan. Management is responsible for: • Establishing policies, procedures and responsibilities for comprehensive contingency planning. • Reviewing and approving the contingency plan annually, documenting such reviews in writing If the organization receives information processing from a service bureau, management must also: • Evaluate the adequacy of contingency plans for its service bureau • Ensure that its contingency plan is compatible with its service bureau’s plan Conclusion Disaster recovery planning involves more than off-site storage or backup processing. Organizations should also develop written, comprehensive disaster recovery plans that address all the critical operations and functions of the business. The plan should include documented and tested procedures, which, if followed, will ensure the ongoing availability of critical resources and continuity of operations. The probability of a disaster occurring in an organization is highly uncertain. A disaster plan, however, is similar to liability insurance: it provides a certain level of comfort in knowing that if a major catastrophe occurs, it will not result in financial disaster. Insurance alone is not adequate because it may not compensate for the incalculable loss of business during the interruption or the business that never returns. Other reasons to develop a comprehensive disaster recovery plan include: • Minimizing potential economic loss. • Decreasing potential exposures • Reducing the probability of occurrence • Reducing disruptions to operations • Ensuring organizational stability • Providing an orderly recovery • Minimizing insurance premiums • Reducing reliance on certain key individuals • Protecting the assets of the organization • Ensuring the safety of personnel and customers • Minimizing decision-making during a disastrous event • Minimizing legal liability.

Differences Between Disconnectors, Load Switches, Switch Disconnectors and Circuit Breakers https://phasorcorp.com/differences-disconnectors-load-switches-switch-disconnectors-circuit-breakers/ https://phasorcorp.com/differences-disconnectors-load-switches-switch-disconnectors-circuit-breakers/#comments Fri, 20 Jun 2014 13:02:26 +0000 http://phasorcorp.com/?p=702
Differences between disconnectors, load switches, switch disconnectors and circuit breakers

Device Types

Various types of device are available for carrying out the switching and protection tasks listed under title that are specially designed to fulfill the respective requirements. The various parts of IEC 60947 (Low voltage switchgear and controlgear) specify the design, performance and test features of the devices. The most important features of the main device types are presented below:

  1. Disconnectors (isolating switches)
  2. Load switches
  3. Switch disconnectors
  4. Circuit breakers

Switch symbols: The horizontal line in the switch symbol of the contacts indicates that they fulfill the isolating function

1. Disconnectors (isolating switches)

Legrand's Isolating switches The disconnector is a mechanical device that fulfills in the open position the requirements specified for the isolation function (IEC 60947-1).

The purpose of the isolating function is to cut off the supply from all or a discrete section of the installation by separating the installation or section from every source of electrical energy for reasons of safety.

The key factor here is the opening distance. Isolation must be guaranteed from pole to pole and from input to output, whether this is by means of a visible isolation gap or by suitable design features within the device (mechanical interlocking mechanism).

A device fulfills the isolating function stipulated under IEC 60947-1 when in the “Open” position the isolation at a defined withstand voltage is assured between the open contacts of the main circuit of the switchgear.

It must also be equipped with an indicator device in relation to the position of the movable contacts. This position indicator must be linked in a secure, reliable way to the actuator, whereby the position indicator can also serve as actuator, provided that it can only display the position “Open” in the “OFF” position, when all moving contacts are in the “Open” position. This is to be verified by testing. According to IEC 60947-3, an isolator must only be able to make and break a circuit, if either a current of negligible size is switched on or off, or if during switching no noticeable voltage difference between the terminals of each pole occurs.

Under normal conditions it can conduct operational currents as well as under abnormal conditions larger currents (e.g. short-circuit currents) for a certain period.

The isolator function can be realized with a variety of devices such as for example in disconnectors, fuse-disconnectors, switch-disconnectors, fuse-switch disconnectors and circuit breakers with isolating function. Go back to Index ↑

2. Load switches

4 pole load break switch with visible breaking and a remote tripping function Load switches (or only “switches”) are mechanical switching devices capable of making, carrying and breaking currents under normal circuit conditions which may include specified operating overload conditions and also carrying for a specified time currents under specified abnormal circuit conditions such as those of short-circuit.

A load switch may have a short-circuit making capacity, however it does not have a short-circuit breaking capacity (IEC 60947-1 and -3).

Short-circuit currents can be conducted (high short-circuit withstand capacity), but not be switched-off. For load switches the range of designs is similarly wide as for isolator switches, for example “normal” (load) switches, fuse-switches, circuit breakers.

Fuse-switches are not legally permitted in all countries.

3. Switch disconnectors

Switch disconnectors; Left -  ABB's motorized switch disconnector 160-2500A; Right - Schneider Electric's low-voltage disconnect switch with free tripping 80-3200A (photo credit: directindustry.com) Switch disconnectors combine the properties of (load) switches and disconnectors. In this case, too, there are a variety of designs such as “normal” switch disconnectors, fuse- switch-disconnectors and circuit breakers.

Fuse-switch-disconnectors are not legally permitted in all countries.

Go back to Index ↑

4. Circuit breakers

Schneider Electric's low voltage moulded case circuit breaker (MCCB) type Compact NSX Circuit breakers are mechanical switching devices, capable of making, carrying and breaking currents under normal circuit conditions and also making, carrying for a specified time and breaking currents under specified abnormal circuit conditions such as those of short-circuit (IEC 60947-2). They thus also fulfill the requirements of (load) switches. Circuit breakers are often designed so that they can fulfill the requirements for disconnectors.
