Solid Insulation Material Dielectric Loss and Dielectric Constant Measuring Electrode

00.jpg

Introduction

 

The electrode is used in dielectric constant εr and dielectric loss tgδ test for solid electrical material such as insulation paint, resin, rubber, fibrillated product, laminate, mica product, plastic, cable, film composite, porcelain and glass. The electrode is designed to use under power frequency of 50Hz, and comply with international standard GB1409-78.

The electrode is in three electrode structure, which could effectively eliminate surface leaking current and make the electrical filed tending to uniform electric field.
