Abstract
Disclosed are systems and methods for monitoring an electrical wire. A safety device utilized to monitor the wire may include at least one current sensing device, at least one voltage sensing device, and at least one processing component. The current sensing device measures a current on at least one conductor of the wire. The voltage sensing device measures a voltage associated with the safety device. The at least one processing component receives the measurements and identifies, based upon the current measurement, an overcurrent event. The processing component then compares the voltage measurement to a stored voltage value and determines, based upon the comparison, that a difference between the voltage measurement and the stored voltage value satisfies a threshold condition. The processing component directs, based upon the determination, at least one relay to be opened to discontinue provision of an electrical power signal onto the electrical wire.
