Also known as High Voltage Dielectric Loss Tester or Fully Automatic Dielectric Loss Tester



The Dielectric Loss Tester, also known as High Voltage Dielectric Loss Tester or Fully Automatic Dielectric Loss Tester, is a high-precision instrument used to accurately measure the dielectric loss tangent (tanδ) and capacitance (Cx) of high-voltage power equipment.

It is mainly used in power plants, substations, and other field or laboratory settings to assess the insulation status of high-voltage equipment such as transformers, instrument transformers, bushings, capacitors, and power cables. It is a key device in preventive testing, acceptance inspection, and fault diagnosis of power equipment.
