PowerSafe provides testing and commissioning services for all types of instrument transformers rated up to 500kV. Instrument transformers are used for metering and protection purposes in power systems and come in many configurations and designs. It is important that they be tested before initial use and at regular intervals to guarantee the highest possible security of the supply. The testing requirements for instrument transformers are dependant on the type, configuration and class of equipment. A normal inspection and test routine would be to carry out tests and inspections on the instrument transformer alone and secondly to ensure connection to connected relays and meters are correct.
