Import 20kv Megohmmeter 15kv Digital — Buy in wholesale FOB from Supplier in China

The 20KV Megohmmeter 15KV Digital is a professional-grade insulation resistance tester designed for high-voltage substations and power generation facilities to evaluate the integrity of electrical insulation in large transformers, rotating machinery, and power cables. This digital megohmmeter features selectable test voltages ranging from 0.25kV to 15kV, allowing operators to perform insulation resistance measurements across various voltage classes. The instrument incorporates strong anti-electric field interference capability up to 2mA at 50Hz, enabling accurate testing near energized equipment in 500kV substations without requiring wire disconnection.

The unit offers a wide resistance measurement range from 0.5MΩ to 200,000MΩ with high resolution for precise readings critical for assessing insulation condition. The short-circuit test current exceeds 5mA with a maximum of 15mA, making this instrument suitable for testing high-capacity and high-inductance equipment such as large power transformers and long-length cables. The megohmmeter includes a timekeeping function that assists operators in recording absorption ratio and polarization index values, which are essential diagnostic parameters for evaluating insulation aging and moisture content in electrical equipment.

Primary purchasers include electrical utilities, power plant operators, industrial maintenance departments, and testing laboratories responsible for preventive maintenance of high-voltage electrical systems. The instrument enables testing of remote power cables, buried cables, and other electrical insulation in strong interference environments.
