Substation Maintenance and Testing

Maintenance and TestingAIMS Maintains and Tests Your Power Systems

Proper calibration and testing of protective relays is a critical aspect of any power distribution system maintenance program. Because these devices are extremely sensitive, inaccurate calibration can cause nuisance trips or even result in an unprotected system if the settings are too high or too low. If the system is not coordinated, tripping the wrong relay can not only shut down entire sections of a system, it can also cause substantial damage.

AIMS uses your Short-Circuit Analysis & Coordination Study to verify and test the configuration of your protective relays, circuit breakers, switches and other protective devices. Coordination of all these components is essential, since we want to minimize the affected areas by having only the protective device nearest the fault catch it.
