Round Core Current Transformer

Round Core Current Transformer

Round core current transformer has the advantage of very low leakage of magnetic flux, thus is the most popular one. Due to the high permeability nanocrystalline cores or composite cores, our mini current transformers have compact size and very low phase angle error and amplitude error. We can make “I” type or “+” type (cross) hole, which is very convenient, if the customers want to integrate the CT with a latching relay. We can also provide split current transformer, which can measure the electric current without disconnecting the circuit.
