The modern surge arrester tester features a large-screen color LCD display, supporting touchscreen or Windows-style interface operation.

A surge arrester tester typically consists of two parts: a main unit and a voltage acquisition unit.

Surge arrester testers are specialized instruments used for on-site and laboratory testing of various electrical parameters of surge arresters.

A ground resistance tester is used to measure the resistance of a buried grounding electrode and the soil current dissipation resistance.

Transformer oil, as a crucial insulating medium in power equipment, directly impacts the safe operation and lifespan of transformers.

A transformer oil tester is a precision instrument specifically designed to test various parameters in transformer oil.

The following precautions should be taken when using a withstand voltage tester:

A withstand voltage tester is an instrument used to test the insulation performance and withstand voltage capability of electrical equipment, componen

A voltage higher than the normal operating voltage is applied to the insulation of the device under test for a specified period of time.

Partial discharge testing instruments commonly employ detection methods including the direct method, bridge balance method, and current pulse method.

Partial discharge testers are designed with different considerations in system architecture, human-computer interaction, and portability, depending on

Partial discharge is a major cause of insulation degradation in power transmission and transformation equipment, and also a significant indicator and
