ICT is the transformer used in the three phase test bench to calibrate the three phase meters with closed I-P links.

Electric energy meter with closed I-P links are used wider and wider. If the under test meter not allowed to open the closed I-P links, It is need ICT to isolate the current circuit to get a 1:1 current ratio to fulfill the calibration.

Each ICT is fitted in each meter position.
