Abstract
An Energy Reducing Maintenance Switch (ERMS) connected to an electrical circuit includes: a switch that activates the ERMS upon being closed or turned-on; a normally-open first contact that closes to activate an instantaneous trip setting of a relay upon activation of the ERMS; and a second contact. The instantaneous trip controls an arc flash in the electrical circuit, and the activated instantaneous trip setting of the relay reduces time of the arc flash in the electrical circuit. Upon activation of the ERMS, the second contact closes to initiate ERMS activation alert in two or more forms.
Claims19
An Energy Reducing Maintenance Switch (ERMS) connected to an electrical circuit comprising:
- a switch that activates the ERMS upon being closed or turned-on;
- a normally-open first contact that closes to activate an instantaneous trip setting of a relay upon activation of the ERMS;
- and
- a second contact,
- wherein instantaneous trip controls an arc flash in the electrical circuit,
- wherein the activated instantaneous trip setting of the relay reduces time to contain the arc flash in the electrical circuit, and
- wherein, upon activation of the ERMS, the second contact closes to initiate ERMS activation alert in two or more forms.
A method of operating an Energy Reducing Maintenance Switch (ERMS) connected to an electrical circuit, the method comprising:
- detecting a signal that a switch of the ERMS is on;
- closing a first contact of the ERMS, upon detection of the signal that the switch is on;
- activating an instantaneous trip setting of a relay upon closing of the first contact,
- closing a second contact of the ERMS, upon detection of the signal that the switch is on;
- initiating ERMS activation alert in two or more forms, upon closing of the second contact;
- wherein instantaneous trip is set by the relay to control an arc flash, and
- wherein the activated instantaneous trip setting reduces time to contain the arc flash in the electrical circuit.
A non-transitory computer readable medium (CRM) storing instructions for operation of an Energy Reducing Maintenance Switch (ERMS) connected to an electrical circuit, the operation comprising:
- detecting a signal that a switch of the ERMS is on;
- closing a first contact of the ERMS, upon detection of the signal that the switch is on;
- activating an instantaneous trip setting of a relay upon closing of the first contact;
- closing a second contact of the ERMS, upon detection of the signal that the switch is on;
- and
- initiating ERMS activation alert in two or more forms, upon closing of the second contact,
- wherein instantaneous trip is set by the relay to control an arc flash, and
- wherein the activated instantaneous trip setting reduces time to contain the arc flash in the electrical circuit.
