6 FAQs about [35kV capacitor protection function]
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
What is a capacitor bank?
As you already know, capacitor banks are normally used in medium voltage networks to generate reactive power to industries etc. Capacitor banks are, almost always, equipped with a series reactors to limit the inrush current.
What is the protection of shunt capacitor banks?
Protection of shunt capacitor banks is described in references [8.10.1] to [8.10.5]. Shunt capacitor banks (SCBs) are widely used in transmission and distribution networks to produce reac-tive power support.
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.
How shunt capacitor banks affect power system performance?
Located in relevant places such as in the vicinity of load centers the use of SCBs has beneficial effect on power system performance: increased power factor, reduced losses, improved system capacity and better voltage level at load points. Shunt capacitor banks are protected against faults that are due to imposed external or internal conditions.
What causes a flashover in a capacitor bank?
If the phases of the bank are constructed in distinct separate structures, a flashover within the capacitor bank will begin as a short circuit fault over of a single-series group. Such a fault produces very little phase overcurrent. For this type of fault, fast protection is provided by the unbalance protection.
