What standards are applicable to the production and inspection of capacitors?

To the production and inspection of the capacitors, the standards (VDE [German Association for the Electrical, Electronic, andInformation Technologies] and IEC provisions and requirements) that, unless otherwise explicitly agreed upon by the parties, are effective at the time of the order confirmation will apply.

Where should a capacitor unit be inspected?

Capacitor Unit(s) shall first be visually inspected at a distance no less than 0.8m from exposed Capacitor Unit terminals, Charged Capacitor Rack(s), fuse(s) or associated busbars and connections to identify any abnormal Capacitor Unit(s).

Do I need a discharge stick on all capacitor units?

Hence the requirement to use a Discharge Stick on all Capacitor Unit(s). A Capacitor Unit is made safe by connecting together both terminals to its metal container. In some configurations one of the terminals is inherently at the container and rack potential.

Does IEC 60831 apply to power filter capacitors?

This part of IEC 60831 also applies to capacitors intended for use in power filter circuits. Additional definitions, requirements, and tests for power filter capacitors are given in Annex A.

How many capacitor banks are there in a high voltage circuit?

There may be more than one Capacitor Bank in a High Voltage circuit (i.e. Bank A, B, C) type registered device for the purpose of discharging a Capacitor Unit which may be Charged. Type Registered lead used for short-circuiting an individual Capacitor Unit.

What is an abnormal capacitor unit?

Abnormal Capacitor Unit(s) are those that show signs of excessive bulging, major leaks or broken bushings. If any abnormal Capacitor Unit(s) are found, especially following a fault, then advice from a Technical Specialist may be sought.
