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. 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.

4. Dielectric withstand test - Wikipedia

   en.wikipedia.org/wiki/Dielectric_withstand_test

   A dielectric withstand test may be done as a factory test on new equipment, or may be done on apparatus already in service as a routine maintenance test. [2] An insulation test set; in this pattern, a hand-cranked generator provides the high voltage and the scale is directly calibrated in megohms. Voltage withstand testing is done with a high ...

6. 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 ...

7. Insulation monitoring device - Wikipedia

   en.wikipedia.org/wiki/Insulation_monitoring_device

   Insulation monitoring device. An insulation monitoring device monitors the ungrounded system between an active phase conductor and earth. It is intended to give an alert (light and sound) or disconnect the power supply when the resistance between the two conductors drops below a set value, usually 50 k Ω (sample of IEC standard for medical ...
