Current Transformers

Current transformers or (CT’s), also known as Core Balance Current Transformers or Current Transducers, are instruments that are used to reduce or multiply the current from a high current into a lower current or vice versa. This is done so that the power can then be easily managed by Relays and measurement tools for electrical circuits and processes. Current Transformers consist of a core,...
