conductors or the air between a grounded conductor and an ungrounded conductor. Arc faults can occur when as little as 120 volts are present, but arc flashes that result from medium and high voltage switchgear involve dangerous amounts of energy that could cause critical injuries. In a facility’s switchgear, the power source for an arc [...]

Tips for Selecting the Right Power Generation Service
A service that specializes in Emergency Power Supply Systems (EPSS) is an important resource for facilities that have generators. An EPSS is a significant investment, one that protects the business of a company by providing electricity generation during an outage. If your company needs a service to maintain its EPSS, the tips below will help [...]
Backup Power Specialists in Carolina: EPSS Services that Every Facility Needs
Has it been awhile since your facility had its emergency power supply system (EPSS) serviced? If so, the next power outage could find you where you do not want to be—in the dark. A facility’s EPSS should be maintained in one of two ways: by in house technicians that specialize in EPSS maintenance, or by [...]
Generator Testing in Georgia: What Every Facility Manager Should Know
Despite its infrequent use, a backup generator (a.k.a. genset) requires regular servicing. Consisting of testing and maintenance, this servicing prepares it to supply power during a power outage. In the Georgia area, Prime Power is the leading generator services provider for commercial and industrial power users. If your facility’s genset has been tested infrequently, now [...]
Switchgear Breaker Testing in Carolina: Testing for MV Circuit Breakers
The interrupting mechanism and voltage class determine the types of tests that switchgear requires. The focus is on breaker testing for medium voltage (MV) gear that interrupts arc faults using oil, air, vacuum, or SF6 (sulfur hexafluoride) breakers. In the Carolina area, Prime Power performs switchgear breaker testing for commercial and industrial power users. Essential [...]
Switchgear Testing in Georgia: 10 Essential Tests that Support Circuit Breakers
The condition of a building’s switchgear can impact the safety of its environment. Without regular maintenance and testing, circuit breakers can develop problems that lead to unextinguished arc faults and arc flashes that damage assets and injure workers. In Georgia, Prime Power performs switchgear testing for commercial and industrial power users to help prevent these [...]
Emergency Generator Inspection: Seven Reasons Why Generators Fail
The older a generator gets, the more likely it is to experience a mechanical emergency. Because a generator (a.k.a. genset) is operated infrequently, certain problems can go undetected by monthly tests, which are typically conducted for thirty minutes—less time than a genset might run during a power outage. When a problem occurs that limits or [...]
NFPA 110 Emergency Generator Testing Requirements
The National Fire Protection Association (NFPA) establishes safety standards that protect commercial building occupants against various dangers, one of which is improperly lit egress paths during low visibility. Besides requiring luminescent egress markings and safety signage to be placed along egress paths, the NFPA also requires regular testing of emergency generators. Combined, these measures help [...]
Diesel Emergency Generator Systems: How to Avoid Wet Stacking
National Fire Protection Association (NFPA) code 110 defines wet stacking as the accumulation of unburned fuel or carbon on a diesel generator’s exhaust side. To measure wet stacking, emergency power technicians measure the temperature of a generator’s exhaust gas. Once the extent of wet stacking is confirmed, technicians suggest ways to eliminate it. If left [...]
OSHA Fire Protection Guidelines for Commercial and Industrial Buildings
The Occupational Safety and Health Association (OSHA) establishes workplace safety standards for commercial and industrial buildings. Covering an array of safety concerns, OSHA standards apply to different workplaces in different ways, but OSHA fire protection standards apply to all workplaces that are regulated by the association. OSHA guidelines for fire protection are industry specific, but [...]
