1、 Ensure the safety and reliable operation of equipmentPrevent overload riskAccurately measuring the actual capacity of a transformer can avoid its long-term overload operation. Overload can cause abnormal temperature rise in the winding, accelerate insulation aging, and even lead to fire or explo

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
