This new three -phase test instrument addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

Out-of-step protection is a critical component of modern power system protection schemes—its importance has grown ...

Today’s high power semiconductor test applications are increasingly demanding, requiring test instrumentation capable of characterizing higher rated voltages and peak currents than ever before. Many ...

Most test setups need only positive voltages to power the device under test (DUT). Some devices require negative voltages as well. Test voltages aren’t always fixed, though. Their value and/or ...

In the not-so-distant past, electrical workers routinely racked out breakers in the normal course of their jobs. They did this with little concern or knowledge of the hazards to which they were ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...
