Instrument Transformers are transformers that convert high currents or voltages into measurable and standardized currents or voltages. These are then proportional and in-phased to the primary signal. They are intended to supply electrical measuring instruments, meters, relays or other electrical devices. Furthermore, the connected measuring and protective devices are electrically insulated against live parts.
