UHV-640 Insulating Oil Dielectric Loss Tester -Catalog

Product catalog summary

Product Introduction
The UHV-640 Insulating Oil Dielectric Loss Tester is designed for measuring the dielectric loss and resistivity of insulating oil in power equipment. Traditional methods like the bridge method are cumbersome and prone to errors. This tester, developed by Wuhan UHV Power Technology Co., Ltd., offers a modern solution with high precision and efficiency, adhering to GB5654-2007 standards.

Product Features

Integrated functions for oil cup, heating, temperature control, and pressure regulation.
Large-screen color LCD display with thermal printing and simple Chinese character menu operation.
Automatic calibration of the empty cup.
Protection against over-voltage, over-current, and temperature limits.
Intermediate frequency induction heating for uniform and rapid heating.
Direct temperature measurement via a probe in the electrode cup.
Built-in sine wave generator for standard 50Hz high-power test power supply.
