People can thank voltage transformers, a kind of instrument transformer, for decreasing voltage intensity to safe levels and subsequently transporting the reduced power to homes. Transformers, which ...

Voltage transformers (VT) are used in electrical grids for metering and/or protection purposes. The high requirements regarding their precision demand a calibration ...

Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

Inrush currents associated with motor starting and transformer energizing can cause interaction problems with other loads in a facility or on the power system, particularly sags that trip loads.

Why is understanding high-voltage oil-filled transformer bushings so critical? High-voltage power transformers are an essential component of our nation's electric grid infrastructure. Bushings are the ...

Allegro MicroSystems has integrated power, voltage and current monitoring into a single chip with reinforced isolation. Only a handful of resistors are needed to complete the high-voltage interface ...
