1、 Core functionsHigh voltage electrical testingNon contact electrical testing: When the bare wire voltage exceeds a specific threshold (such as 60kV or 110kV), there is no need to touch the line, and the instrument can determine the charged state through induced electric field. When approaching th

1. Grounding protection of power systemSubstation and transmission lines:Test the resistance value of grounding electrodes for equipment such as transformers, lightning arresters, and iron towers to ensure that lightning strikes or fault currents can be safely introduced into the ground, avoiding eq

1. Power system and transmission and distribution equipmentThe insulation resistance tester is a core tool for power system maintenance, mainly used to test the insulation performance of equipment such as transformers, generators, cables, and switchgear. Specific scenarios include:Substations and tr

1、 Ensure the safe and stable operation of the power systemPower quality issues, such as voltage dips, harmonic distortion, three-phase imbalance, etc., may cause power grid failures or even collapse. For example, harmonic pollution can cause transformers and cables to overheat, accelerate insulati
