The EZCT-S2 from Vanguard Instruments is a second-generation, microprocessor-based, current transformer set. The EZCT-S2 will perform the current transformer saturation test and the CT (current ...

Current transformer (CT) saturation presents a critical challenge in the realm of power system protection and automation. Under fault conditions, the magnetic core of a CT may become saturated ...

Electromagnetic current transformers, invented more than 100 years ago, are today the most widespread type of preliminary current converters, used in organizing metrological channels for commercial ...

Accurately modeling the saturation present in transformer iron cores, so that it fully reflects all of the effects saturation has on the current waveforms, presents a challenging task. Over the years, ...

The transformer and output inductor give 1500 V of isolation. With the configuration shown, the supply provides +12 V at 3 A and −12 V at 1 A. Windings can also be configured for a ±2-A, or a ...
