2. 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.

3. 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 ...

4. 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 ...

5. 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.

6. Portable appliance testing - Wikipedia

   en.wikipedia.org/wiki/Portable_appliance_testing

   PAT testing can be conducted manually, using a collection of standard test gear, including a high-voltage insulation tester and a low resistance ohm meter for earth continuity. But generally it is conducted with an automatic tester that applies a sequence of tests in turn.

7. Cable fault location - Wikipedia

   en.wikipedia.org/wiki/Cable_fault_location

   Insulation and resistance measurement provides information on the fault characteristics. An insulation test measures the insulation resistance between conductor and screen; from the periodic measurement of resistance you can derive the absorption properties of the insulating material.
