The magnetic balance test, i.e. a test of the flux ratio, is appropriate as a routine electrical field test and as an additional diagnostic method when a fault is suspected in the core.

Transmission Substations – ElectraNet

Transformers. Transformers are the largest single piece of equipment in a substation. They work by increasing the voltage of the electricity produced by the generator, from an average of between 12,000 and 22,000 Volts, up to transmission voltages of 132,000 and 275,000 Volts, and then back down to 66,000, 33,000 or 11,000 Volts to enter the distribution network.
