How is a capacitor measured?

A capacitor is measured by the size of its capacitance. A capacitance is the electric capacity of a capacitor, i.e. the amount of electrically charged carriers it can store. ɛ r . The relative dielectric constant can have values between ɛ r = 1 (air) and ɛ r ~ 10,000 (special ceramic materials).

What are the stipulations for individual capacitor series?

The stipulations for individual capacitor series are in accordance with the CECC type specifications. The rated or operational pulse rise time is specified as 1/10 of the test pulse rise time. The pulse rise time F given in V/µsec is also indirectly the maximum current capacity.

What is a series capacitor?

The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard:

What is the resistance of a paper & plastic film capacitor?

Paper and plastic film capacitors usually have insulation resistance values ranging from 6000 to 12000 MΩ. This is not quite explicit because the x C is also used to measure the quality of the insulation. gives the time in seconds during which the voltage between the terminating wires of a charged capacitor decreases to 37% due to self-discharging.

What are the correction factors for metallized plastic film capacitors?

Correction factors which are specific to the different applications, result from temperature and/or voltage stress capacity according to the following tables. Today metallized plastic film capacitors with Polyester film achieve the best values. Here the expected value is about 2 fit. This results in a failure rate of 10 fit.

What are the requirements for testing AC capacitive current switching devices?

Common requirements for testing of AC capacitive current switching devices with nominal system voltage above 1000 V are provided in this standard. This standard provides common requirements for testing of ac capacitive current switching devices over 1000 V. This standard will not contain a Purpose clause.
