Overcurrent relays tester TPN
- Testers and Measuring Instruments
TPN is a constant DC current injector capable for testing overcurrent relays. Output current is 200 or 400 A, depending on the version, and device is supplied from 230 VAC network. Apart of tripping point of the relays, other time related parameters are also tested. TPN device features with preprogrammed probing current functions, is portable and very easy to use, thanks to touch screen. Measurement results can be stored on memory for convenient test report generations.
