Product description

Product Introduction

Main Feature

　　◆ It can accurately measure the capacity of various transformers, passive measurement, convenient and accurate;

　　◆ It can measure the no-load current, no-load loss, short-circuit voltage, short-circuit loss, and zero sequence impedance of various types of transformers;

　　◆ It can automatically perform waveform distortion correction, temperature correction, voltage correction (no-load test under non-rated voltage), current correction (short-circuit test under non-rated current conditions), and the operator only needs to input the correction index instrument according to the transformer type Automatically calculate the corrected result, which is very suitable for units that have not done short-circuit test conditions for a slightly larger capacity transformer;

　　◆ External voltage transformer and current transformer are allowed to perform extended range measurement, and can measure the tested product with any parameter.
