Plastic film capacitors typically have an insulation resistance of 6 to 12 G?.
2.
The insulation resistance test is not a substitute for the high voltage test.
3.
For the same reason, high insulation resistance and high breakdown voltage are required.
4.
Megger measures insulation Resistance at high voltage, and VOM measures volts and ohms.
5.
For electrolytic capacitors the insulation resistance of the dielectric is termed " leakage current ".
6.
Insulation resistance respectively the self-discharge constant can be reduced if humidity penetrates into the winding.
7.
Another cause of nuisance tripping is due to accumulated or burden currents caused by items with lowered insulation resistance.
8.
Typical applications of multiplex switching include capacitor leakage, insulation resistance, and contact resistance test systems for multiple devices.
9.
The minimum acceptable value of resistance for a product to pass an insulation resistance test is 1 mega Ohm ( 1000 kohms ).
10.
The permissible changes of capacitance, dissipation factor and insulation resistance vary with the film material, and are specified in the relevant data sheet.
