6 FAQs about [Replacement of fuse inside capacitor]

Are capacitor fuses capacitive limited?

Most capacitor fuses have a maximum power frequency fault current that they can interrupt. These currents may be different for inductive and capacitively limited faults. For ungrounded or multi-series group banks, the faults are capacitive limited.

Do capacitor strings need a fuse?

There is no individual fuse protection for the capacitor strings. If a single string unit fails, the current flow is unaffected due to the presence of other capacitors in series. This allows for extended operation before replacing the faulty unit. Fuse units are not required for immediate replacement of the faulty unit in this type of bank.

How do I choose a shunt capacitor fuses?

For shunt capacitor applications, the energy is equal to 3.19 joules per kVar. The available energy is then compared to the rating of the fuse and capacitor unit. This is one criteria for selecting either expulsion or current-limiting fuses for a given application. If the parallel energy is above 20 kJ or 6000 kVar, we apply current-limiting fuses.

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 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.

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.
