A Substation Operator’s job is to inspect, operate, and
maintain electrical substations, which contain equipment
that transforms electricity from one voltage to another so
that it can be safely used by customers.

another way: An electrical grid is like a relay race. The
starting line is the power plant and the finish line is the
customer’s home or business. In between, the baton —
electricity — is passed between hands several times, which
helps it travel farther, faster.

first maintance is required in substation.check the all the reading in control room.A Substation Operator’s is to inspect, operate, and maintain electrical substations, which contain equipment that transforms electricity from one voltage to another so that it can be safely used by customers.

Put another way: An electrical grid is like a relay race. The starting line is the power plant and the finish line is the customer’s home or business. In between, the baton — electricity — is passed between hands several times, which helps it travel farther, faster.

Within an electrical distribution system, the points at which the baton is passed are the electrical substations, while the relay runner who does the passing is the Substation Operator.

While connecting the flood light plug on to the 415 V distribution panel,there was spark and the cable got burnt. Three ignitors of the flood light also burnt of. The lamps are of 400 W (total 6 lamps) connected through 1.5 mm2 cable. The plug was immediately removed from the circuit. There was a 30 mA RCD connected and a 250 A MCCB; however both did not trip. What could be the possible reasons for the circuit devices not to trip?Can someone assist please. Additional info if needed can be provided.
