Most utilities in the United States are required to comply with North American Electric Reliability Corporation (NERC) regulations. Some of these regulations require utilities to develop performance-based, condition-based, or time-based maintenance programs, and the execution of these programs is what opens a window of opportunity for testing companies to offer services oriented to help utilities achieve their maintenance testing needs. …

Circuit breaker types and technologies have a rich history. Whether we are referring to arc-extinction methods such as oil, air-blast, air magnetic, SF6, newer non-SF6 technologies, and vacuum, or to energy storage methods such as mechanical springs, pneumatics, and hydraulics, the use of and preference for these technologies has changed vastly over time. It is essential to understand diagnostic testing …

A power system is a complex network of key high-voltage components working in synchrony to provide electricity. Power transformers, which help step up and step down voltage so power can be transmitted over long distances, are designed to be in continuous operation. Hence, the life and reliability of transformers is of paramount importance. Multiple factors affect the life and performance …

The conventional exciting current and loss test is an open-circuit measurement of current and loss, typically performed from the high-voltage side of the transformer, using low voltage (up to 10 kV), single-phase, power frequency (50/60 Hz) excitation. For this test, the well-known approach to data analysis, first introduced in 1968, relies on comparison and evaluation of the per-phase readings against …
Imagine this scenario: You visit a local generating station that needs relay testing. They direct you to a switchyard relay house with microprocessor relays and test switches. The customer wants the relays tested, but the breakers are part of a bigger ring bus system that is powering loads to the city. The breakers cannot be tripped. What special considerations can …
