Protective Relay Settings
Detect system disturbances and isolate the disturbances
Protective Relay Settings & Services
The primary function of protective relays in a power system is to detect system disturbances and isolate the disturbances by activating the appropriate circuit interrupting devices. Protective relays play a critical role in the power system reliability and it is imperative that they are applied and configured correctly. Relays that are set too sensitive can be the cause of unwarranted system outages. Relays that are not sensitive enough may fail to detect or isolate faults which could lead to a catastrophic power system failure. Root 3 engineers can provide system settings that maximize equipment fault clearing and minimize exposure to nuisance trips. The principal engineers of Root 3 have over 40 combined years of experience performing calculations, developing settings, troubleshooting and commissioning protective relays.
