Protective Relay Testing

PTS is highly experienced in complex relay testing and in relay repairs & maintenance.

Protective relay testing is an integral part of our business. From commissioning new utility substations and installing new medium-voltage switchgear to maintenance and testing at antiquated electrical facilities, relay maintenance and testing is core to assuring proper protection of the electrical system.

PTS has a relay repair facility adequate for most electro-mechanical relays and some solid-state relay components. Since parts are acquired (and depleted) on a regular basis, contact us for specific requests.
