Protective relays safeguard the most expensive equipment in the power system. The performance of these ralays needs to be checked / verified during commissioning and at periodic intervals. To check these ralays the protection engineer needs a reliable tool -A relay test set that incorporates State of the art hardware suitable for the field working conditions easy to operate, flexible and powerful software. With close interaction with relay manufacturers, Protection engineers and our expertise in designing and manufacturing relay test sets based on DSP technology, Tesient has launched a new, state of the art platform of relay test sets MP3000A. It can cater to most of the demanding applications in testing different types of modern relays.
