Motor Control Functional Testing

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
