- PROCEDURE:
- When EB power fails, immediately start the DG set.
- Check and ensure the Voltage, RPM, Frequency & Oil pressure.
- Close the DG control panel ACB.
- Close the DG incomer ACB in the power control center.
- Concerned engineering personnel has to switch on the AHU’s, DHU’s, utility equipments and remaining loads.
- When EB power resumes check and ensure the 3 Phase voltages should be in-between 415 – 420 Volts.
- Intimate to the production in- charge for soft shut down of all the loads.
- Open the DG incomer ACB in the PCC panel.
- Close the EB incomer ACB in the PCC panel.
- Open DG control panel ACB.
- Stop the DG set after 5 minutes idle running.
- Above mentioned EB power to DG power or DG power to EB power changeover procedure should be complete within 02 minutes only.
