What is tan-delta test ?

Tan-delta test is also know as dielectric losss testing. Dielectric loss refers to the energy loss that occurs in a dielectric material (such as the insulation of a transformer) when an electric field is applied to it. The dielectric loss is caused by the electrical resistance of the material, which results in the conversion of electrical energy into heat.

Prioritizing Safety: The Critical Importance of Preventive Maintenance for Electrical Equipment

The maintenance of electrical equipment is a key point that cannot be ignored in the entire production work. It not only provides guarantee for the production of enterprises, but also vigorously promotes the development of electrical equipment in China. Therefore, for now, it is of great significance to study the preventive daily maintenance of electrical equipment.

VLF Hipot Test Equipment

What is VLF testing ?

VLF testing is a method to test Medium voltage and high voltage cable for verifying the cable insulation . VLF diagnostic testing is a withstand voltage test usually carried out at a frequency of between 0.1 Hz and 0.01 Hz rather than 50/60 Hz.

AC Resonance Test System Knowledge

Series resonance is related with circuit and series connection. It is a resonance condition that usually occurs in series circuits. Generally, A series resonance test system is classified into two types regulating the induction and regulating frequency. It is composed by an exciting transformer, variable frequency power, capacitive voltage divider and reactor.

What is hipot test ?

Hipot test is short for high potential test and it is also called dielectric withstand test or pressure test or insulation test. Hipot test is a nondestructive test that determines the effectiveness of its insulation for withstanding over transient high voltage.
