Avoid expensive and time-consuming repairs with regular testing and maintenance of circuit breakers or protection devices. Regular maintenance is mandatory to meet work safety standards, to ensure proper operation.
Primary Injection Testing – With periodic testing of low and medium voltage circuit breakers, our team performs a complete system test — examining its response time when overloaded and under fault current conditions. We also verify the system matches the short circuit coordination study to ensure the electrical distribution system is properly attached.
Secondary Injection Testing – This type of testing inspects the solid-state trip unit without using primary current. Specially designed power supply units and test sets are used during this process. If the trip unit is not functioning, it should be replaced.
Air Circuit Breaker (ACB) Testing & Calibration – ACBs are designed to break circuits at high current or low voltage conditions. The effectiveness of ACB protections cannot be guaranteed or even determined until proper testing has been performed. In addition to inspecting the physical and mechanical conditions, we perform all mechanical operator and contact alignment tests on both the breaker and its operating mechanism in accordance with manufacturer’s published data.
Molded Case Circuit Breaker Testing – According to the Institute of Electrical and Electronics Engineers (IEEE), reliable and sustainable molded case circuit breakers are a major factor in maintaining safety at any facility.
Oil Circuit Breakers (OCBs) Testing – Our team provides regular visual inspection for physical damage, loose anchorage, alignment, and grounding. We check mechanical operations and contact alignment on the circuit breaker and its operating mechanism. Additionally, we check for oil leaks, conditioning, contact resistance, insulation resistance, etc.
Power Circuit Breaker Testing – Before conducting electrical testing, our team visually inspects the equipment and mechanisms — including safety interlocks — for any signs of damage. We inspect physical and mechanical conditions, fit and alignment, connections, fuses, contact/pole resistance, etc.
Vacuum Circuit Breaker Testing – In addition to inspecting all of the components, electrical testing includes high potential, insulation resistance, contact resistance, time travel analysis and vacuum bottle integrity.
Forefront Electrical Testing technicians protect equipment from ground faults — contact between an energized conductor and ground or equipment frame. Our technicians conduct thorough examination of insulation breakdowns that could be the result of damp, wet or dusty environments. Grounding electrical systems provide protection against electrical faults — which can reduce shock hazards and lightning. We test per NEC 230.95 code.
Ongoing testing of power transformers ensures efficient operation of equipment and safety for personnel. Electrical, thermal and mechanical sustainability of the system requires ongoing testing in accordance with national standards from the Institute of Electrical and Electronics Engineers (IEEE) and American National Standards Institute (ANSI). Testing protocol is dependent on the type of transformer, contractor or utility provider. Typical services include:
Current transformers (CTs) measure alternating current — scaling larger values of voltage down to small ones that can be easily measured. Each CT has specific ratings that determine what type of CT should be used. CT tests use transformer test instruments to determine whether the CT is operating normally and that power levels are within the acceptable limits.
Unlike CTs, Potential transformers (PTs) measure voltage. PTs analyze and reduce high voltage values into lower ones. Without PTs, technicians who service meters during transformer testing can be put at considerable risk.
CT and PT testing make sure instrument transformers are operating the way they should and that the current and voltage remain within the proper framework.
