15KV Digital Insulation Resistance Tester

https://www.mktester.com/ground-resistance-tester/15kv-digital-insulation-resistance-tester.htmlOverview：

The instrument is designed for HV substations and power plants to test the characteristic of large HV transformer, electric machines and appliances, remote power cable or buried cable and other electrical insulation resistance in strong interference environment. It also can be widely used for testing characteristics of insulation resistance in other area.
