Systems, methods, and program products for testing electrical loops included in control circuits of electrical power systems

A method of testing a plurality of electrical loops included in a control circuit, the method comprising:

• configuring a first electrical loop of the plurality of electrical loops in a first electrical setting by adjusting an operational characteristic of at least one electrical switch of the first electrical loop,
• wherein each electrical loop of the plurality of electrical loops includes:
• a phase line,
• a return line operably connected to the phase line, the return line including a relay, and
• the at least one electrical switch operably coupled between the phase line and the return line;
• supplying a voltage across the first electrical loop in the first electrical setting via the phase line;
• determining an actual electrical status of the first electrical loop in the first electrical setting based on whether the relay of the return line detects the supplied voltage;
• and
• detecting a fault in the first electrical loop in response to the determined actual electrical status of the first electrical loop in the first electrical setting differing from an expected electrical status of the first electrical loop in the first electrical setting.

A computer program product comprising program code, which when executed by at least one computing device, causes the at least one computing device to test a plurality of electrical loops of a control circuit, by performing processes including:

• configuring a first electrical loop of the plurality of electrical loops in a first electrical setting by adjusting an operational characteristic of at least one electrical switch of the first electrical loop,
• wherein each electrical loop of the plurality of electrical loops includes:
• a phase line,
• a return line operably connected to the phase line, the return line including a relay, and
• the at least one electrical switch operably coupled between the phase line and the return line;
• supplying a voltage across the first electrical loop in the first electrical setting via the phase line;
• determining an actual electrical status of the first electrical loop in the first electrical setting based on whether the relay of the return line detects the supplied voltage;
• and
• detecting a fault in the first electrical loop in response to the determined actual electrical status of the first electrical loop in the first electrical setting differing from an expected electrical status of the first electrical loop in the first electrical setting.
