Insulation Testing With Dielectric Absorption Test
A poorly insulated electrical device poses danger both to the electrical system and the user. This makes it prudent to invest in high quality and sophisticated electrical test equipment when performing insulation testing.
The dielectric absorption test is one such test that gives reliable and accurate results regarding insulation of a device. The working principle behind the testing procedure is that the resistance offered by the insulation shall increase with time as the atoms of the insulator gets polarized by the DC voltage offered by the tester.
