Capacitor banks provide an economical and reliable method to reduce losses, improve system voltage and overall power quality. This paper discusses design considerations and system implications for Eaton''s Cooper PowerTM series externally fused, internally fused or fuseless capacitor banks.
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.
related to the starting of the motor defined in IEC 60644. The capacitor bank protection fuse-links are described in IEC 60549 (High-voltage fuses for the external protection of shunt capacitors) . Also in this case the fuse should meet the requirements described in the general standard IEC 6028
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.
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.
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.
In this design, a fuse is simply a piece of wire specifically selected based on the internal design of the unit to melt under fault conditions. Because each element is protected with a fuse inside the capacitor unit, the I2R loss is much higher (e.g. 50% higher) compared to unfused unit construction.

The main purpose of the fuse on a capacitor bank is to clear a fault if a capacitor unit or any of the accessories fail. The fuse must clear the fault quickly to prevent any of the equipment from failing violently. Ruptures of capacitors have historically been problematic, so fusing is normally tight.

The fuse cartridge striker, besides performing the function of signalling tripping, can be associated with the device for turning off the operating- disconnecting switch and/or with the external indicator device. Besides H.R.C. fuses, accessories can be supplied such as the specific fuse holder bases and the trip signalling devices.
Fuse operation is caused by raising the temperature of the fuse element above its melting point. Fuse melting is an ener-gy function.
