6 Frequently Asked Questions about “Parallel capacitor fuse voltage”
What is a high voltage capacitor fuse?
For high voltage capacitor fuses, this is generally defined as 8.3, 15.5 or 23 kV, the distribution system maximum voltages. Other voltage ratings may be available for special applications. When a capacitor fails, the energy stored in its series group of capacitors is available to dump into the combination of the failed capacitor and fuse.
Why is parallel energy a non-issue for internally fused capacitor banks?
Parallel energy has typically been viewed as a non-issue for internally fused capacitor banks because the current limiting fuses are commonly used. However, fuse sizing/rating must still be considered when designing the unit to ensure fusing selection is appropriate to handle discharge energy into the shorted element through its fuse.
What is a capacitor fuse used for?
The fuse, by its design, avoids absorbing all of the available energy on the series group. This fuse is used for capacitor banks with a large number of parallel capacitors. It can be used on applications with essentially infinite parallel stored energy, as long as sufficient back voltage can be developed to force the current to extinguish.
What voltage should a capacitor be protected?
Voltage: The voltage of the capacitor being protected should be less than or equal to the voltage of the fuse selected. The nearest available fuse should be used to ensure that the voltage developed by the fuse during interruption does not damage the system.
What are unfused and internally fused capacitors?
Both unfused and internally fused capacitor units are constructed from smaller capacitors, commonly referred to as elements or packs. These elements each have an individual voltage and kilovolt amps reactive (kvar) rating. These elements are connected in series and parallel combinations to achieve the required voltage and kvar rating of the unit.
Can a clxp fuse be used with multiple capacitors?
The fuse is usually applied to series, large shunt and DC capacitor banks. Because of the high back voltage that is developed, this fuse must be used with several capacitors in parallel to limit the voltage build up, or a flashover may occur elsewhere in the capacitor bank. The CLXP cannot be used in inductively limited fault applications.
