The metalizing film, capacitors, and Power Factor Correction Capacitors are our main focus.
What is the international standard for motor capacitors?
This International Standard applies to motor capacitors intended for connection to windings ofasynchronous motors supplied from a single-phase system having a frequency up to andincluding 100 Hz, and to capacitors to be connected to three-phase asynchronous motors sothat these motors may be supplied from a single-phase system.
What is the international standard for capacitor banks?
This International Standard is applicable to low-voltage a.c. capacitor banks intended to beused for power factor correction purposes, equipped with a built-in switchgear and controlgearapparatus capable of connecting to or disconnecting from the mains part (s) of the bank withthe aim to correct its power factor.
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.
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.
What is the rated voltage of a capacitor?
The rated voltage of a capacitor is limited to 10 000 V. (The operating frequency of the systems in which these capacitors are used is usually up to 15 kHz, while the pulse frequencies may be up to 5 to 10 times the operating frequency.)
