2. Electrical safety testing - Wikipedia

   en.wikipedia.org/wiki/Electrical_safety_testing

   Acceptable values of insulation resistance vary depending on circuit purpose, industry, and country. Typically, standards will dictate acceptable values. An insulation resistance test can be used for simple go/no-go testing, or for periodic condition assessment, where routine insulation resistance tests are performed, with the results tracked ...

3. 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 ...

4. Electrical isolation test - Wikipedia

   en.wikipedia.org/wiki/Electrical_isolation_test

   A minimum acceptable resistance value is usually specified (typically in the mega ohm (MΩ) range per circuit tested). Multiple circuits having a common return may be tested simultaneously, provided the minimum allowable resistance value is based on the number of circuits in parallel. Five basic isolation test configurations exist: [3]

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. Comparative Tracking Index - Wikipedia

   en.wikipedia.org/wiki/Comparative_Tracking_Index

   The Comparative Tracking Index (CTI) is used to measure the electrical breakdown (tracking) properties of an insulating material. Tracking is an electrical breakdown on the surface of an insulating material wherein an initial exposure to electrical arcing heat carbonizes the material. The carbonized areas are more conductive than the pristine ...

7. Partial discharge - Wikipedia

   en.wikipedia.org/wiki/Partial_discharge

   Partial discharge. In electrical engineering, partial discharge (PD) is a localized dielectric breakdown (DB) (which does not completely bridge the space between the two conductors) of a small portion of a solid or fluid electrical insulation (EI) system under high voltage (HV) stress. While a corona discharge (CD) is usually revealed by a ...
