Product description

Product Introduction

　　It is used to accurately measure the insulation loss factor tgδ and capacitance Cx of various high-voltage electrical equipment, and can identify defects and hidden dangers caused by pollution, cracking, perforation, and dampness of electrical insulation equipment. It is suitable for the measurement of transformers, transformers, bushings, power cables, capacitors, insulators, high-voltage switches, lightning arresters and other equipment.

Main Feature

　　◆The instrument is equipped with a large screen (105mm×65mm) Chinese menu interface, the screen display is divided into two parts, the left is the function menu area, and the right is the relevant status information prompt. Every step is very clear, and the operator does not need professional training. use;

　　◆The instrument is equipped with a calendar chip and a large-capacity memory, which can save the test results in chronological order, and can view historical records at any time and print out;

　　◆The instrument can be tested in various methods such as forward connection, reverse connection, CVT self-excitation method, etc.;

　　◆The instrument can correctly measure the dielectric loss value and capacitance value of the CVT without removing the high voltage lead of the CVT;

　　◆The inverter and sampling circuit inside the instrument are all digitally controlled, and the output voltage is continuously adjustable;

　　◆The instrument has multiple protection measures and functions such as input voltage fluctuation, output short circuit, overvoltage, overcurrent, temperature, grounding detection, etc., to ensure the safety and reliability of the instrument.
