Description

Automatically provides knee-point voltage/current, 10% (5%)
error curve, accurate limit factor (ALF), instrument security factor
(FS), secondary time constant (Ts), residual magnetism coefficient
(Kr), saturated and unsaturated inductance, and other CT and PT
parameters.

Tests comply with standards such as GB20840.1 (IEC60044-1), GB20840.2 (IEC60044-6),
and GB20840.3 for various types of transformers, and automatically selects the appropriate standard
for testing based on the type and level of the transformer.

Based on advanced low-frequency testing principles, it can handle CT tests with knee points up to
45kV.
.The device can store 2000 sets of test data without loss upon power failure. After the test is

completed, the data can be saved to a PC via a USB drive, and analyzed using software to generate
a WORD report.

Testing is simple and convenient, with one button to complete CT direct resistance, excitation,
transformation ratio, and polarity tests. Except for load tests, all other CT tests use the same wiring
method.。
