    Product Details of UHV-105A CT PT Characteristic Tester

    Product Introduction

    CT PT Characteristic Tester is a portable instrument designed for on-site verification of Protection-class (P-class) Current Transformers (CTs) and Voltage Transformers (VTs/PTs). It performs key tests including excitation characteristic (knee-point, saturation), turns/ratio testing, polarity verification, core demagnetization (degaussing), 5% and 10% error curve derivation, secondary circuit continuity and burden measurement, secondary winding insulation withstand (power frequency AC), and secondary load testing. Equipped with an integrated LCD display, a built-in micro printer for instant field reports, and USB data export capabilities, it offers comprehensive functionality with streamlined operation for efficient field use.
