Products > TC - Medium Voltage > Current transformer for protection
Current transformers for protection are intended to reduce current levels in order to ensure safety for people and equipment as well as galvanic insulation between the power circuit and the protection circuit, thus avoiding the circulation of currents in the ground mesh. In addition, they filter and reduce noises and improve the harmonic distortion rate.
