1. Ground ResistanceDefinition: The total resistance between the grounding device and the earth, reflecting the ability of current to diffuse from the grounding body to the surrounding soil.Measurement principle: By injecting a test current (usually AC, to avoid polarization effects) into the ground

Environmental conditionsTemperature: The typical working environment temperature is -10 ℃ to+40 ℃ to avoid extreme high or low temperatures affecting equipment stability.Humidity: Relative humidity ≤ 85%, to prevent electrical components from getting damp or short circuiting.Ventilation: Use in a

1. Structural designDry type test transformer:Using air or epoxy resin as insulation medium, without liquid filling, the winding is usually encapsulated in solid insulation material (such as epoxy resin) through vacuum casting process.The shell is mostly an open or closed metal/non-metal structure,

The grounding resistance tester is a specialized instrument used to measure the resistance value of grounding systems, widely used in fields such as power, communication, construction, and industry to ensure the safety and effectiveness of grounding systems. The following are the main application sc
