7 - Trades, Transport & Equipment Operators

We use lots of test equipment. There is testing equipment designed for every aspect of a substation, such as a breaker analyzer for testing breaker operations, and a battery analyzer for testing the conductance of batteries.

For insulation testing, we do a bridge test that measures capacitance, or the ability of a substance to store an electric charge. We also use multi-meters to tell us the voltage and current of electrical circuits of equipment. To measure the resistance of a station ground grid and of ground chains we use a microhmmeter.
