Below is the method of the Motor control functional test
-
set the isolator of the RCU in the field to open position
-
remove the lock out tag out (LOTO), then rack in the feeder and close the isolator on the draw-out unit.
-
measure the incoming voltage, check the phase sequence of the incoming power at field
-
Open the isolator at draw-out unit
-
Closed the isolator at the RCU
-
Closed the isolator at the draw-out unit
-
initiate start at the substation
-
verify the rotation of the motor, if the rotation is correct direction
-
then verify the running signal of the motor if it is link to DCS
-
initiate trip at the substation draw-out unit
-
verify the status of the motor at the field as well as in the DCS
-
reset trip at substation draw-out unit
-
verify again the status in DCS
-
initiate start in the field (RCU)
-
verify the status at DCS, if confirmed running signal
-
then stop the motor at RCU and verify the status in DCS if confirmed
-
Open the isolator in substation draw-unit and rack out
-
Put Lock out tag out (LOTO)
-
Test complete
