Abstract
An adapter for testing electrical equipment can include a first receptacle end having at least one first coupling feature, where the at least one first coupling feature is configured to couple to a power source and a first electrical device, where the first receptacle end is configured to receive from the power source at least one first test signal and send the at least one first test signal to the first electrical device. The adapter can also include a sensing device configured to receive at least one first response signal from the first electrical device, where the at least one first response signal is in response to and based on the first electrical device receiving the at least one first test signal.

An adapter for testing electrical equipment, the adapter comprising:
- a first receptacle end comprising at least one first connector end, wherein the at least one first connector end is configured to couple to a power source connector end of a first high voltage electrical device, wherein the first receptacle end is configured to send at least one first test signal, generated by a power source, to the first high voltage electrical device, wherein the at least one first test signal is configured to test a first electrical integrity of the first high voltage electrical device;
- a second receptacle end comprising at least one second connector end, wherein the at least one second connector end is configured to couple to an electrical device connector end of the power source, wherein the power source connector end of the first high voltage electrical device and the electrical device connector end of the power source are pre-configured to directly couple to each other in an absence of the adapter, and wherein the power source provides primary power to the first high voltage electrical device during normal operating conditions;
- and
- a sensing device configured to receive at least one first response signal from the first high voltage electrical device, wherein the at least one first response signal is in response to and based on the first high voltage electrical device receiving the at least one first test signal, wherein the at least one first response signal comprises information about the electrical integrity of the first high voltage electrical device,
- wherein the at least one first response signal provides an indication of a phase-to-phase fault or a phase-to-ground fault.

A controller of an adapter for testing electrical equipment, the controller comprising:
- a metering module configured to receive a response signal from a high voltage electrical device;
- and
- a control engine coupled to the metering module, wherein the control engine follows a plurality of instructions to:
- initiate, using reserve power provided by an energy storage device of the adapter, a test signal to the high voltage electrical device through at least one first connector end of the adapter coupled to a power source connector end of the high voltage electrical device, wherein the test signal is configured to test for fault potential at the high voltage electrical device;
- receive the response signal from the metering module in response to and based on the test signal, wherein the response signal comprises information about the electrical integrity of the high voltage electrical device;
- evaluate the electrical integrity of the high voltage electrical device based on the response signal relative to historical response signals received in response to historical test signals initiated from a power source to the high voltage electrical device, wherein at least one second connector end of the adapter is coupled to an electrical device connector end of the power source, wherein the power source connector end of the high voltage electrical device and the electrical device connector end of the power source are pre-configured to be coupled to each other in an absence of the adapter;
- and
- communicate when a fault event of the high voltage electrical device is likely to occur,
- wherein the historical test signals are further configured to test for the fault potential at the high voltage electrical device,
- wherein the control engine is disposed between the power source and the high voltage electrical device, wherein the power source provides power to the high voltage electrical device through the controller during the normal operating conditions.
