Energy reducing maintenance switch system and method for implementing an energy reducing maintenance switch system
An ERMS system and a method for implementing an ERMS system are disclosed. The ERMS system includes: a self-powered relay comprising a control circuit that controls the self-powered relay to work under one of a first mode and a second mode; a portable power box; and an electrical interface connecting the portable power box to the self-powered relay. Under the second mode, the self-powered relay is configured to reduce energy level in an arc flash event. Upon receiving a signal from the portable power box via the electrical interface, the control circuit controls the self-powered relay to work under the second mode.
