  1. Electrical safety testing - Wikipedia

    en.wikipedia.org/wiki/Electrical_safety_testing

    An insulation resistance test (IR test) measures the electrical resistance of insulation by applying a voltage between two locations, and measuring the resultant current flow. Proper safety precautions must be taken when doing this test, such as exclusion zones, making sure no wires are exposed, and personal protective equipment is worn.

  2. Megohmmeter - Wikipedia

    en.wikipedia.org/wiki/Megohmmeter

    Megohmmeter M1101M. A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators. [1] Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations.

  3. Electrical isolation test - Wikipedia

    en.wikipedia.org/wiki/Electrical_isolation_test

    Electrical isolation test. In electrical engineering, an electrical isolation test is a direct current (DC) or alternating current (AC) resistance test that is performed on sub-systems of an electronic system to verify that a specified level of isolation resistance is met. Isolation testing may also be conducted between one or more electrical ...

    Measures current without physical connection. Curve tracer. Applies swept signals to a device and allows display of the response. Cos Phi Meter. Measures the power factor. Distortionmeter. Measures the distortion added to a circuit. Electricity meter. Measures the amount of energy dissipated.

  5. Dielectric withstand test - Wikipedia

    en.wikipedia.org/wiki/Dielectric_withstand_test

    Dielectric withstand test. In electrical engineering, a dielectric withstand test (or pressure test, high potential or hipot test or insulation test) is an electrical safety test performed on a component or product to determine the effectiveness of its insulation. The test may be between mutually insulated sections of a part, or energized parts ...

  7. Ohmmeter - Wikipedia

    en.wikipedia.org/wiki/Ohmmeter

    An analog ohmmeter. An ohmmeter is an electrical instrument that measures electrical resistance (the opposition offered by a circuit or component to the flow of electric current). Multimeters also function as ohmmeters when in resistance-measuring mode. An ohmmeter applies current to the circuit or component whose resistance is to be measured.
