WR.20S Three Phase Transformer Winding Resistance Tester
About the WR.20S:

  • DC winding resistance tester is designed to measure DC resistance of inductive devices, such as transformers and power inductors.

​

  • The instrument is compact in size and has a high level of accuracy with fast measurement cycle.

​

  • WR.20S is ideal for measuring transformer windings and DC resistance of large power inductance equipment.

​

  • Polyphase winding resistance and de-magnetization function.

​

  • Suitable for Transformers up to 7MVA / 35kV models.
