Capacitors adopt national standards

This Standards Publication applies to capacitors designed for shunt connections to alternating-current power transmission and distribution systems operating at frequencies of 50 or 60 hertz …

How difficult is it to calibrate capacitors for use as standards?

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.

What are the recommendations for the capacitor part?

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.

Would the world turn without capacitors and resistors?

The world would not turn without capacitors and resistors! Electronic and electrical circuits cannot be built without capacitors or resistors. In a modern electronic circuit each integrated circuit (IC) needs on average ten capacitors and/or resistors to function.

How many capacitors & resistors does an IC need?

In a modern electronic circuit each integrated circuit (IC) needs on average ten capacitors and/or resistors to function. This has created an annual market of over 4000 billion capacitors and resistors (including varistors and thermistors) with business value of approximately 25 billion USD. The website will be updated regularly, for more info:

What is a series capacitor?

A series capacitor is a type of capacitor intended for high-voltage power systems and covered by this standard. The primary focus of the standard is on transmission applications and series capacitor units and banks.

Where do capacitors come from?

Production has moved to low-cost countries and the primary users of passive components – the consumer goods industry – have for a large part left Europe, Japan and North America for the Asia-Pacific region. In 2000, Europe, Japan and North America produced about 55% of all capacitors; in 2015, their share of production was 20%.
