. Apparent
power calculated multiplying current times voltage. Arc faults result from worn damaged
insulation and are common cause fires.
Analog Output output from system that can continuously vary over a
range current voltage such milliamps 10
volts.The
unit for apparent power the volt-ampere, abbreviated “VA. Arc chutes are used reduce contact
damage quickly extinguishing the arc created when contacts
open.
