Voltage transients in MV power systems have been observed to contribute to failures of both power and instrument transformers in data centers in recent years. This white paper provides a background ...

What distinguishes a medium voltage circuit breaker from other types is not the enclosure or operating mechanism, but the method of arc extinction. The interruption medium governs arc energy, ...

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 ...

Here are the steps required to select the transformer and how to design the circuit needed to meet the end use in a manner that prevents transformer saturation Average current-mode control (CMC) ...

Omicron has introduced a way to test current transformers at all lifecycle stages by using a testing method called "the modeling concept". The "traditional" way of testing a current transformer is to ...

For utilities, proper protection against high voltage transient overvoltages and overloads is critical to ensure maximum life of their power transformers. Failure to do so can result in significant ...
