Protective and Measuring Transformers

Instrument transformers are used for measuring or protection functions because they can transform high voltages and currents proportionately in-phase. So they are used either to measure and record the transmitted power or to feed protection devices with evaluable signals, which enable the protection device to e.g. tripping a switching device. Moreover, they isolate electricity from live portions of the switchgear related measurement or protection/safety devices.
