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.

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 ...

Note: All Code references are based on the 2014 NEC. The NEC has separate sections for transformer feeder protection and transformer protection. Article 240 lists requirements for transformer feeder ...

Average current-mode control (CMC) requires that the total waveform of the current be reconstructed for the control loop. This article presents the steps required to select the transformer and how to ...

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 ...
