Protective Relay Calibration
Relays are very sensitive equipment which require proper calibration, coordination, and of course, maintenance. Improper calibration can lead to either nuisance trips or an unprotected system if they are set too low or too high. Lack of coordination can shut down an unnecessarily large portion of a system in the event of a fault by tripping the wrong relay. Maintenance will keep your relays operating and ensure a protected system.
Please refer to our coordination study page for more information on relay testing.
