Protective Device Coordination Analysis
Proper application and coordination of over-current relays and other protective devices is vital in a system for providing reliable electrical service. A&E Training Services expert engineers bring the critical experience needed for the proper application of ANSI and NEC requirements to equipment protection.
In addition to relays that respond to short circuits, low-voltage breakers, differential, directional, power, under-voltage, out-of-step, and other special protective relays often need to be set. A&E Training Services coordination study will include detailed tables listing the recommended settings and discussion of any limitations.
