8. OUTPUT RELAY CHECKS This is to verify the healthiness of the Control output relay healthiness. Operate each Spare output through “ Commissioning Test “ on front LCD, Check continuity of the contact that closes. -

Scroll to “Commissioning Test “, use to test mode. Change “Test Mode“ to Contact Blocked. Under Test pattern identify the output to close. “Apply Test” using the “ Contact test” option. Reset the output relays by setting cell [COMMISSIONING TESTS, Contact Test] to “Remove Test”.

Note: Only spare outputs shall be checked using above procedure and other Outputs shall be checked during respective functional test.

FINAL SETTING TEST OF GENERATOR PROTECTION RELAY TYPE: MICOM P345 9. MEASUREMENT CHECK Note: - This test is intended to verify the CT/VT inputs and CT Ratio, VT Ratio setting in the local relay. - During the injection on one phase, the LCD will show that the angle of that phase changing randomly but angle measurement is not required. When inject 3ph current, the LCD will display correct angles. VTR:
