Automatic 3-phase Relay Test System
Model: RELAYSTAR-806
The RELAYSTAR-806 is a programmable and automatic relay test system, which permits for the automatic verification of protection relays, such as those used in medium and high voltage power system.
All hardware parts of the RELAYSTAR-806 kit are housed in a 3U case, that contains: the power supply, the interface circuits, the control boards, the voltage and current amplifiers, the embedded industrial PC, 8-inch LCD screen, keyboard and mouse. It can be operated locally and complete all tests without external PC.
The RELAYSTAR-806 kit operates in connection with a computer, that controls it via the Ethernet port. It allows the kit to interpret all commands received from the computer and to transmit test results via running RELAYSTAR software on a computer or laptop with Windows operating system.
The RELAYSTAR software running on the PC allows the user to:
●Control all current and voltage outputs, for the simulation of all types of faults: in particular, faults that are produced on a distribution network with the neutral connected to ground.
●Change the output in a ramp or step mode.
●Define the state of inputs and outputs between two fault simulations.
●Simulate complex evolution, with faults that change during the test.
●Save the test report in Word format into PC directly.
