Electric heating and electrical one” is not a standard industry term or a single device name.
Based on the context of the power industry and electrical testing, it is most likely an abbreviation, miswriting, or specific combination of the following situations: “Electric heating” and “Electrical” combined tests: refers to the comprehensive testing project of electric heating equipment tests (e.g., heating elements, temperature rise tests) and electrical performance tests (e.g., insulation, resistance, withstand voltage). “Primary electrical” miswriting: In power systems, “primary equipment” (e.g., transformers, circuit breakers, busbars) often requires high-current temperature rise (electrothermal effect) tests. The user may intend to express “thermal/electrical testing of primary electrical equipment”. Specific device model or series: Some manufacturers may package “high-current generator” (used to generate thermal effects) and “DC resistance tester” together, calling it “integrated electric heating and electrical testing system” or similar names (e.g., “electric heating and electrical instrument”). Course or standard number: It could be a textbook (e.g., “Electric Heating and Electrical Technology Volume 1”) or an internal standard code of a company. Combined with your previous two questions (high-current generator, DC resistance tester), the most likely meaning is: a comprehensive testing scenario using a high-current generator for “electrothermal effect” (temperature rise) tests, combined with electrical parameter measurements. To provide you with the most accurate information, I will analyze in detail the core scenario of “integrated electric heating and electrical testing” (i.e., using high current for temperature rise tests and related electrical measurements), and cover possible related equipment. Core Scenario: Integrated Electric Heating and Electrical Testing (Temperature Rise Test) In the manufacturing and maintenance of power equipment, “electric heating” usually refers to the thermal effect generated by current passing through conductors (
