The Relay Testing Equipment is a portable apparatus which is designed for checking the operating characteristic of protective relays on site. Ever present in every day operation of electrical power system is the possibility of the occurance of faults . Since a relay in the system is called into action to deal with a fault only once in a long while, its failure to operate correctly on that occasion means Severe damage to plant or waste of money spent on installation. Periodic Field testing is the best way of ensuring the integrity of the protective relays. But the position is complicated because of the fact that the protective relay is solely concerned with fault conditions and hence it cannot readily be tested under normal operating conditions.

Potential transformers voltage in High Voltage System is not possible because of insulation problem of measuring instruments. It is also not possible to apply high voltage directly to protective relays used for system protection due to high insulation problem. Therefore voltage transformers are used to step down high voltage to a low value accurately in proportion to their ratios.

Phantom load test set Simulates load conditions by providing adjustable voltage, current and power factor, for in house and site testing of 3 phase KWh Meters.

Instrument transformers Long lasting, can be designed in tape insulated varnished type and resin moulded as per customers requirements in different shapes and sizes. the leading manufacturers of HT CTs.PTs. indoor dry type as well as outdoor oil cooled type.
