Product Description
The RELAYSTAR-806 is universal and portable protection relay test set with three current outputs and four voltage outputs to test single and three phase protective relays.
The RELAYSTAR-806 comprises of three independent current output channels and four independent voltage output channels. This enables the unit to be used as a complete single-phase equipment (voltage, current, and phase angle between them) or, with channels synchronised, as a three phase current or four phase voltage generator from a single phase mains input.
The RELAYSTAR-806 also allows optional connection to a computer for either automatic testing of relays or control of the equipment using Windows compatible software.

Main Features
1) Embedded industrial PC with 8" LCD screen
2) Stand-alone operation, no PC required to operate
3) 3-phase current+ 4-phase voltage outputs
4) Perform multi-phase tests
5) Perform acceptance or troubleshooting tests in COMTRADE format
6) Dynamic GPS satellite synchronized end-to- end testing capability
