The given coordinates will take you to a position from where you will be able to obtain the substation plant and equipment number (SPENS No) which is engraved on the gate label.
You will need this six digit number in order to work out the cache coordinates.
Cache co-ords:- N 50 48.X E 000 14.Y
Where X is the maximum length of distributor cable #1(to the nearest metre) when the permissible voltage drop in the cable from the substation to the consumer connected at the end is 15volts at full load.
The voltage drop per metre per amp of load for the cable is 0.0004volts and full load for the cable is:- (4th digit x 4th digit x 6th digit) + 3rd digit amps.
And Y is the maximum length of distributor cable #2(to the nearest metre) when the permissible voltage drop in the cable from the substation to the consumer connected at the end is 30volts at full load.
The voltage drop per metre per amp of load for the cable is 0.0004volts and full load for the cable is:- (1st digit x 2nd digit x 4th digit) - 4th digit amps.
