A method of determining a prospective short circuit current for an electrical system including a source includes connecting a test load between either: (i) a first phase line and a second phase line of the electrical system or (ii) the first phase line and the neutral line of the electrical system, employing a sensor coupled to the electrical system to measure a voltage drop across the test load, determining a voltage value based on at least the measured voltage drop across the test load, determining a total effective impedance for the first phase line to the source, and determining the prospective short circuit current based on the voltage value and the total effective impedance.

An electrical connector testing system can include a first connector end and a controller coupled to first connector end. The system can also include an electrical load coupled to the first connector end, where the electrical load includes an electrical cable and a second connector end coupled to an end of the electrical cable. The controller can determine whether an adverse electrical condition exists with respect to the electrical load before allowing power to flow between the first connector end and the second connector end.

Systems and methods for testing electrical connectors

A system and method for testing of electrical connections, conductors, and loads prior to energizing those connections is disclosed. For example, an interlocking socket can comprise a receptacle designed to be coupled to a connector of a load. The interlocking socket can comprise a microprocessor coupled to the receptacle, the microcontroller operable for testing one or more faults in the connector, a conductor, or the load coupled to the connector. In another example, a microprocessor can be coupled to a switch comprising a conductor, where the microprocessor is operable for testing one or more faults in the conductor or a load coupled to the conductor.

Testing and monitoring of an electrical connection

An arc fault circuit interrupter detector circuit including a super regenerative high frequency receiver is described herein. In one exemplary, non-limiting embodiment, a current measure component determines that a current noise signal within a circuit breaker is occurring at a particular frequency of interest. The super regenerative high frequency receiver receives the current noise signal and, via an oscillator circuit, causes the signal to ramp to a quench voltage, dissipate, and repeat. A microcontroller in communication with the super regenerative high frequency receiver measures a time period of the oscillator circuit's oscillations, and determines an amplitude of the current noise signal based, at least in part, on the time period. If it is determined that the amplitude of the input current signal at the frequency of interest corresponds to an arc fault event, a trip signal is generated to trip the circuit, quenching the arc fault event.
