6 FAQs about [Capacitor over discharge protection]
How does a capacitor discharge a bank?
To discharge the bank, each individual capacitor unit has a resistor to discharge the trapped charge within 5 minutes. Undervoltage or undercurrent protection function with a time delay is used to detect the bank going out of service and prevent closing the breaker until the set time has elapsed.
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.
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 over-discharge protection affect battery life?
Over-discharge protection threshold The over-discharge protection threshold also has an impact on capacity/charge and cell life. A battery will have more capacity per charge if it is discharged all the way. However, this is stressful on the battery and will reduce the lifetime of the battery.
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.
Why are capacitor units imposed to overvoltage?
Capacitor units are imposed to overvoltage across ele-ments within a unit as elements become shorted in case of failure. The overvoltage on the remaining ele-ments shall be considered. Excessive voltage on the remaining elements may lead to cascading failure dur-ing system transient overvoltages [8.10.1].
