Isolated Current Transformer For High Accuracy Current Testing Of Close IP-Link Meter

Isolated Current Transformer for High Accuracy Current Testing of Close IP-Link Meter

A. Isolation Current Transformer (ICT)

Nowadays, more and more energy meter’s current and voltage channel is fixed connection; it is close IP-link meter. For testing of meters with closed IP-link, the unit under test must be supplied with isolated and potential-free current and voltage signals. The previous test bench couldn’t offer such signals, can only test open IP-link meter. TICT-100 series is a precision isolated current transformer (ICT) with active electronic error compensation, can offer the insolated high accuracy current, to test close IP-link meter. TICT-100 series can be installed on the new test bench or used to upgrading the old test bench.

Description:

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.
