Brief Introduction To Inspection Methods For Electrical Fittings (part 2)

10.Pre-insulated Sleeve aging test [ageingtests]

A test that applies a specified aging factor to the test piece so that the service life can be evaluated in a much shorter time than the actual service life;

11. Low-voltage and high-current tests [low-voltagehigh-currenttests]

A test conducted when the voltage is a small percentage of the rated value and the current is the rated value or greater than the rated value;

12. Thermal stability test [thermalstabilitytests]

A test to determine the thermal stability of the temperature and loss of the test piece under specified overload conditions;

13. Radio interference test [radiointerferencetests]

A test to determine the radio interference level of the test piece under the operating voltage;

14. Partial discharge starting voltage test [partialdischarg einceptionvoltagetests

A test to measure the minimum voltage when partial discharge occurs on the surface of a conductor;

15. Coronatests

A glow discharge test in a high electric field with uneven field strength near a conductor;

16. Test for uniformity of galvanized coating

A test to check the uniformity of the coating by replacing metal ions;

17. Impulse loadtests

A test to apply a momentary mechanical dynamic load to a component under specified conditions to simulate the load-bearing capacity of the component under accident conditions;

18. Corrosion resistancetests

A test to test the corrosion resistance of a component under certain temperature and salinity conditions.
