Scope: The scope is a standard for series capacitor banks that are connected in series with the utility transmission system. The banks include capacitors and all the accessory equipment necessary to form a complete equipment.
Capacitor banks store electrical energy in their components and use it to correct power factor lags (or) phase shifts in an alternating current (AC) power supply. This assists in maintaining optimum efficiency & prevents unwanted dips (or) surges in voltage that can harm electrical equipment.
This International Standard is applicable to low-voltage AC shunt capacitor banks intended to be used for power factor correction purposes, possibly equipped with a built-in switchgear and controlgear apparatus capable of connecting to or disconnecting from the mains part (s) of the... A description is not available for this item.
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:
ANSI, IEEE, NEMA or IEC standard is used for testing a power capacitor bank.There are three types of test performed on capacitor banks. They are Design Tests or Type Tests. Production Test or Routine Tests. Field Tests or Pre commissioning Tests.
Installed capacitor banks lose their ability to operate at optimal efficiency if they are not tested or maintained within a certain period of time. Capacitor functioning can deteriorate over time, lowering your power system’s power factor and leading to power factor loss.
