Thermal non-contact voltage and non-contact current devices

A method of operating a non-contact measurement device, the method comprising:

• detecting, via a thermal imaging tool disposed in or on a housing of the non-contact measurement device, infrared radiation from a target scene that includes an electrical circuit;
• producing, via the thermal imaging tool, thermographic image data for the electrical circuit;
• receiving, by at least one processor, the thermographic image data from the thermal imaging tool;
• presenting, via a display subsystem, the thermographic image data that indicates a presence or absence of abnormal heat generation locations in the electrical circuit;
• at least one of:
• sensing, via a non-contact voltage measurement tool (NVMT), a voltage in an insulated conductor of the electrical circuit without galvanically contacting the insulated conductor;
• or
• sensing, via a non-contact current measurement tool (NCMT), a current in an insulated conductor of the electrical circuit without galvanically contacting the insulated conductor;
• receiving, by the at least one processor, measurement data from at least one of the NVMT or the NCMT, the measurement data comprising at least one of a voltage sensor signal from the NVMT or a current sensor signal from the NCMT, the voltage sensor signal indicative of the voltage in an insulated conductor of the electrical circuit under test, and the current sensor signal indicative of the current in an insulated conductor of the electrical circuit under test;
• and
• determining, by the at least one processor, at least one alternating current (AC) electrical parameter based on the received measurement data.

A non-contact measurement device, comprising:

• a thermal imaging tool that, in operation, detects infrared radiation from a target scene that includes an electrical circuit and produces thermographic image data for the electrical circuit;
• a non-contact voltage measurement tool (NVMT) that, in operation, senses a voltage in an insulated conductor of the electrical circuit without galvanically contacting the insulated conductor;
• a non-contact current measurement tool (NCMT) that, in operation, senses a current in an insulated conductor of the electrical circuit without galvanically contacting the insulated conductor;
• at least one nontransitory processor-readable storage medium that stores at least one of processor-executable instructions or data;
• and
• at least one processor communicatively coupled to the at least one nontransitory processor-readable storage medium, the thermal imaging tool, the NVMT, and the NCMT, and in operation the at least one processor:
• receives thermographic image data from the thermal imaging tool;
• provides an indication of a presence or absence of abnormal heat generation locations in the electrical circuit based at least in part on the received thermographic image data;
• receives measurement data from at least one of the NVMT or the NCMT, the measurement data comprising at least one of a voltage sensor signal from the NVMT or a current sensor signal from the NCMT, the voltage sensor signal indicative of the voltage in an insulated conductor of the electrical circuit under test, and the current sensor signal indicative of the current in an insulated conductor of the electrical circuit under test;
• and
• presents at least a portion of the measurement data via the display subsystem in connection with providing an indication based at least in part on the received thermographic image data.
