6 FAQs about [Capacitor with low voltage protection]
What is a capacitor bank's protective control?
The purpose of a capacitor bank’s protective control is to remove the bank from service before any units or any of the elements that make up a capacitor unit are exposed to more than 110% of their voltage rating.
Is tapping across a low-voltage capacitor suitable for fuseless capacitor banks?
Tapping across the low-voltage capacitors is suitable for fuseless capacitor banks. The are certain faults within the bank that the unbalance protection will not detect or other means are required for its clearance.
What is the protection of shunt capacitor bank?
The protection of shunt capacitor bank includes: a) protection against internal bank faults and faults that occur inside the capacitor unit; and, b) protection of the bank against system disturbances. Section 2 of the paper describes the capacitor unit and how they are connected for different bank configurations.
What are the features of low voltage capacitor banks APCQ?
Low-voltage capacitor banks APCQ features include: Dry type resin embedded according to IEC289, IEC 76. Maximum harmonic pollution: 8% THDV with specific spectrum Discover Hitachi Energy's reliable solutions for power quality management with our contactor-switched capacitor banks.
How does a capacitor unbalance protection work?
The unbalance protection should coordinate with the individual capacitor unit fuses so that the fuses operate to isolate the faulty capacitor unit before the protection trips the whole bank. The alarm level is selected according to the first blown fuse giving an early warning of a potential bank failure.
Do capacitor banks need to be protected against short circuits and earth faults?
In addition to the relay functions described above the capacitor banks needs to be protected against short circuits and earth faults. This is done with an ordinary two- or three-phase short circuit protection combined with an earth overcurrent relay. Reference // Protection Application Handbook by ABB
