Three Phase ICT

When testing three-phase energy meters where the voltage and current measurement circuits cannot be separated (closed links), it is necessary to isolate the voltage and current circuits. In multi-meter inspection, due to the complexity of three-phase circuits, the voltage isolation method can no longer meet the needs of actual inspection, and current isolation method is needed to ensure the inspection accuracy.

Product Detail

Features and Functions

■ Provides current isolation for energy meter testing in three-phase systems with non-separable voltage and current circuits, ensuring measurement accuracy during multi-meter testing.

■ Enables accurate equipotential method calibration for both three-phase and single-phase energy meters with non-separable voltage and current circuits, where each meter is independently supplied by an isolation current transformer (CT) .

■ Features three independent 1:1 current transformers per unit, supporting isolated current supply for individual meters in multi-meter setups .

■ Offers a wide current range of 0.05A-120A/0.05A-120A for primary and secondary circuits, Rated range (with 0.01% accuracy): 0.1A–100A/0.1A–100A

■ Single turn through the center, energy saving and high efficiency, the maximum output power of 70VA (I = 100A)

■ Special electronic error compensation technology ensures high accuracy (0.01% class) across the wide range .

■ Provides output secondary open-circuit and overload protection indication, alarm and automatic shorting.

■ External status indication (P1/P2/P3 luminous indicator lights) and control buttons for easy operation.
■ Supports series connection of multiple CTs, with primary inputs connected in series and secondary circuits operating as independent power supply loops for parallel meter testing.
