6 FAQs about [Capacitor relay protection picture]
What is a capacitor bank protection relay?
This relay protects grounded and ungrounded, single- and double-wye capacitor configurations and allows you to obtain full control of your capacitor banks. Combining these components with capacitor bank protection devices expands their functionality.
What is capacitor bank protection?
ABB's capacitor bank protection is used to protect against faults that are due to imposed external or internal conditions in the shunt capacitor banks. Internal faults are caused by failures of capacitor elements composing the capacitor units, and units composing the capacitor bank.
How a voltage sensitive relay is connected to a capacitor bank?
Here the capacitor bank is connected in star and the neutral point is connected to the ground through a potential transformer. A voltage sensitive relay is connected across the secondary of the potential transformer.
What are the different types of protection arrangements for capacitor bank?
There are mainly three types of protection arrangements for capacitor bank. Element Fuse. Bank Protection. Manufacturers usually include built-in fuses in each capacitor element. If a fault occurs in an element, it is automatically disconnected from the rest of the unit. The unit can still function, but with reduced output.
What happens when a capacitor bank is protected by a fuse?
Whenever the individual unit of capacitor bank is protected by fuse, it is necessary to provide discharge resistance in each of the units. While each capacitor unit generally has fuse protection, if a unit fails and its fuse blows, the voltage stress on other units in the same series row increases.
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
