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 ...

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, ...

A current transformer (CT) is a simple, practical and inexpensive means of detecting the presence of AC current. Detecting load current rather than applied voltage is a superior method of determining ...

Technology advancements and new regulatory requirements could reshape how power plant owners operate and maintain large power transformers. Experts outline emerging strategies and call attention to ...

This Idea For Design provides a Spice model for an ideal transformer that sidesteps an issue with an earlier IFD. This model not only works at dc, but also allows for bi-directional operation of the ...

The LLC Resonant Power Converter is a very complex circuit. This blog is the fourth in a series of blogs that attempts to simplify the circuit in order to understand the basics. This series is written ...

Distribution transformers must adhere to NEC and NFPA 70 standards, with specific requirements for overcurrent protection, grounding, and installation based on ...
