NOTE

1.IF ANY BUS DE-ENERGIZED FOR ANY REASON, THE ASSOCIATED CAPACITOR MUST BE OPEN.
WHEN ACCS IS AUTO, AND THIS WILL BE ACHEIVED BY TRIPPING THE CAPACTOR CB WHEN THE ASSOCIATED INCOMER CB WILL OPEN.

2.THE MINIMUM INPUTS TO THE ACCS SHALL CONSIST OF STATUS OF ALL 132kV/13.8kV INCOMER(TRANSFORMER) CBs, BUS TIE CBs,
EACH 13.8kV BUS VOLTAGE, EACH POWER TRANSFORMER'S VAR READINGS ON THE HV SIDE,

NO REPRODUCTION IN FULL OR IN PART SHALL BE OBTAINED FROM THIS DOCUMENT WITHOUT THE WRITTEN CONSENT OF ITS OWNER.
AND STATUS OF LOCKOUT RELAYS OF INCOMER CBs AND CAPACITOR CBs.

3.THE CB OF THE CAPACITOR BANK ONCE SWITCHED OFF SHALL NOT SWITCH ON WITHIN 10MINUTES.
IN ANY CASE THE 13.8kV INCOMER CBs OF THE TRANSFORMERS T-1,T-2&T-3 ARE SWITCHED ON,
THE ASSOCIATED CAPACITOR SHALL NOT SWITCHED ON WITH IN 10 MINUTES.

4.THE ACCS SHALL PREVENT UNDESIRED SWITCHING 'ON' OPERATION OF CBs OF ASSOCIATED CAPACITOR BANKS IN ANY ONE OF THE FOLLOWING CASES:

i. 13.8kV BUS FAULT (86B1 OR 86B2 OR 86B3) OPERATES & 13.8kV CBF.
ii. 13.8kV CAPACITOR FEEDER UNCLEAR FAULTS (MAIN FEEDER CB OR DEDICATED CAPACITOR FEEDER CB LOCKOUT RELAY OPERATES).
iii. 13.8kV INCOMERS LOCKOUT OPERATES.
iv. 13.8kV BUS TIE LOCKOUT OPERATES

1.DURING ACCS AUTO MODE, WHEN ANY 13.8kV INCOMER CB SWITCHED OFF, MAIN ONE LINE DIAGRAM EA-609704
THE ASSOCIATED CAPACITOR BANK SHALL ALSO SWITCHED OFF BEFORE 13.8kV BUS SECTION CB SWITCHED ON.
THIS CONDITION WILL NOT BE APPLICABLE WHEN ACCS IN ON MANUAL MODE.
2.ACCS CONTROL COMMAND IN AUTO MODE SHOULD NOT CONCERNED BY CONTROL PANEL LOCAL/REMOTE SELECTIVITY.
3.IF ANY CAPACITOR BANK CB IS NOT IN REMOTE AND IN SERVICE MODE IN SWITCHGEAR PANEL,

National Grid SA
ACCS IN AUTO MODE SHOULD NOT ISSUE COMMAND TO THIS CAPACITOR.
D
D 4.DURING ACCS MANUAL OPERATION MODE, BOTH FUNCTIONS (TRANSFORMER LOADING MEASUREMENT MVAR AND
ASSOCIATED BUS VOLTAGE MEASUREMENT) ARE NOT REQUIRED. AUTHORITY SHALL BE GIVEN TO
CONTROL AND FIELD OPERATION THROUGH HARD WIRING OR SWITCHGEAR BCU (NOT THROUGH ACCS RELAY)
TO PUT THE CAPACITOR BANK IN SERVICE OR NOT. UNLESS IF THERE ARE SAFETY REQUIREMENTS OR
PROTECTION INTERLOCK PREVENT CB, OPERATION SHALL BE EXECUTED BY HARDWARE FROM SCHEME AND SOFTWARE FROM SWITCHGEAR BCU.

5.AUTO/MANUAL OPERATION MODE SELECTIVITY SHALL BE EXECUTED

(LOCALLY IN THE PANEL USING PUSH BUTTON OR SPRING RETURN SELECTOR SWITCH) THROUGH
BI-STABLE RELAYS SO THAT MANUAL OPERATION CAN BE CARRIED OUT FROM CONTROL CENTRE.

THIS DRAWING AND THE INFORMATION CONTAINED HEREIN ARE THE SOLE PROPERTY OF
IT SHOULD NOT BE SELECTED FROM ACCS CONTROLLER.
