Relay Testing System

Programmas a computer-aided relay testing and simulation system. The rugged hardware design is built for field use over a wide temperature range, with the possibilities of intelligent software to perform rapid testing, simulation and analysis for power system protection. The system can be operated either with a PC and the FREJA Win software, or without a PC (stand-alone) in the Local mode. The generated values are measured and shown on the built-in display. The system can also be used as a disturbance simulator and create and generate simulated disturbances, or import actual recorded disturbances from e.g. EMTP or COMTRADE files (and edit the wave forms), by using the FREJA SIM Disturbance Simulator Software. Several systems can be synchronized to simulate a T-line or perform end-to-end testing. With the built-in DC source the user can supply the relay protection.
