Primary Injection Test Sets … Getting the Best Performance
Primary injection test sets are high current units designed for testing and adjusting low voltage circuit breakers and other current actuated devices. Typical test sets incorporate a variable high current ac output along with circuitry to measure the reactions of the breaker under test. In concept these are very simple test sets. Inject the desired current level and measure the breaker’s reaction time… simple, right? VIEW DETAILS
Selecting the Right AC Hipot for Testing in the Field
Portable AC hipots are ideal for testing many types of substation apparatus, motors/generators, isophase bus, and other loads requiring an AC withstand test. But did you know that portable AC hipots are offered as either power frequency (50/60 Hz) or Very Low Frequency (VLF) models? Why two styles? VIEW DETAILS

Smart Phones Make Cable Fault Locating Support a Breeze
Wow, I just realized that nearly half of my life has been spent either performing cable fault location or supporting others performing this task. Applications have varied from fiber optic, telecommunication, CATV, LAN and electrical power cabling. So as a little bit of an old timer in CFL I am absolutely amazed with how simple smart phone technology has made the training and support of this craft. VIEW DETAILS
Understanding Compliance and Testing Requirements for Asset Owners
If you are a Generation Owner, Transmission Owner, Distribution Provider or you provide service and maintenance to any of the aforementioned entities you are most likely struggling with maintenance compliance for your protection system. Or more specific, as the North American Electric Reliability Corporation (NERC) defines the Protection System. VIEW DETAILS
