Types of Capacitor Banks
There are three main types of capacitor banks: internally fused, externally fused, and fuseless. Internally Fused Capacitor Banks: In this type, the capacitors and fuse units are housed within the same casing. Each capacitor element is individually protected by a fuse unit. Even if one or more capacitor elements fail, the bank can continue to […]
