6 Frequently Asked Questions about “Capacitors frequently burn out fuses”
How do capacitor current limiting fuses work?
Capacitor current-limiting fuses can be designed to operate in two different ways. The COL fuse uses ribbons with a non-uniform cross section. This configuration allows the fuse to be used to interrupt inductively limited faults. The pressure is generated by the arc contained in the sealed housing.
How do capacitor fuses work?
Over the years, a set of terms has been developed to apply capacitor fuses. The concept of applying fuses should be a simple engineering task; however, fuse operation is a non-linear function. The resistance of fuse elements changes non-linearly as they melt and clear.
What causes a capacitor to stop working?
In some cases, it can even cause the device to stop working entirely. One of the most common causes of capacitor failure is dielectric breakdown. This happens when the insulation between the plates of the capacitor breaks down, allowing current to flow where it should not.
What is a capacitor fusing factor?
The capacitor must be able to absorb this energy with a low probability of case rupture. Fuses are usually applied with some continuous current margin. The margin is typically in the range of 1.3 to 1.65 per unit. This margin is called the fusing factor.
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.
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.
