Product Description
YJS-H Fully Automatic Insulating Oil Dielectric Loss and Reisistivity Tester
Overview
This instrument, designed in accordance with GB/T 5654-2007 / IEC 60247:2004 "Measurement of relative permittivity, dielectric dissipation factor (tan δ) and d.c. resistivity of insulating liquids", measures the dielectric dissipation factor (tan δ) and DC resistivity of insulating oils and other liquid insulating media.
It features an integrated structure, incorporating key components internally:Dielectric test cell, Temperature controller, Temperature sensor, Dielectric loss bridge, AC test power supply, Standard capacitor, High-resistance meter, DC high-voltage source.Utilizing fully digitalized technology, it performs intelligent automated measurements. The instrument is equipped with a color LCD with large screen, a Chinese menu interface with prompts at each step. Test results are automatically stored and can be printed. Non-specialized personnel can operate it proficiently.
