F. 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.
