NEMA intends to develop two American National Standards for capacitors design and testing for DC capacitors and low voltage capacitors. See the draft scopes and outlines below.
How Capacitor Leakage Testers Work. To understand how capacitor leakage testers work, let''s first review what happens inside a capacitor. A capacitor consists of two conductive plates separated by an insulating dielectric material. When a voltage is applied, electric charge builds up on the plates. Positive charge collects on one plate and negative

IEEE Standard for Series Capacitor Banks in Power Systems. This standard represents a significant update to IEEE 824-1994. Series capacitor bank component and bank duty cycle ratings, equipment insulation levels, protective functions, component testing, instruction books, nameplates, and safety are covered in this standard.
Selection and calibration of capacitors for use as Standards is a challenging task, especially since the accuracies required, depening on the application, can be very demanding for the test gear as well as for the secondary- and working-standards used.
2. Capacitance Calibration The precision measurement of capacitors for the purpose of calibration is generally based on a national primary standard of high accuracy, secondary/working Standards derived from it, and a capacitance- (or LCR-) meter used for the measurement (i.e. calibration) of the devices under test (DUT).
The Capacitance Standards we build, in order to achieve high accuracy, are generally of coaxial (also called 'three terminal') type. That means that each of the two terminals of our Capacitance Standards is brought out through a BNC connector, with the shield of the two connectors forming the third terminal.
The recommendations for the capacitor part are given in IEC 60143-1:2004. Specific information about protective equipment can be found in Clause 3 and 10.6. This second edition cancels and replaces the first edition published in 1994 and constitutes a technical revision.
Welcome to the Capacitor Fundamentals Series, where we teach you about the ins and outs of chips capacitors – their properties, product classifications, test standards, and use cases – in order to help you make informed decisions about the right capacitors for your specific applications.
Few capacitance meters are suitable if a higher accuracy needs to be achieved, and also few secondary- and working-Standards support such high accuracy. The meteres suitable comprises traditional manually operated capacitance bridges as well as a few selected capacitance meters.
