These are most commonly used motors. The capacitor start capacitor run motors are used in ceiling fans, blowers and air-circulators. These motors are available upto 6 kW. Example
Capacitor banks are mainly installed to provide capacitive reactive compensation/ power factor correction. Normally in factories or other high power consuming places, most probably there will be a consumption of the inductive load. Inductive voltage means that there must be a lagging power factor.
The purpose of a capacitor bank's protective control is to remove the bank from service before any units or any of the elements that make up a capacitor unit are exposed to more than 110% of their voltage rating.
For Delta banks, a similar principle can be adopted using an “H” configuration of capacitors on each phase. For single Wye-grounded neutral capacitor banks, the most straight-forward protective control is neutral-current-type relaying.
The internal fuses for internally fused units used in capacitor banks follow the same basic criteria, but in those cases, the fuse characteristics are applied by the manufacturer: Voltage rating – Must be larger than the capacitor unit voltage rating.
When capacitor units in a capacitor bank fail, the amount of increase in voltage across the remaining units depends on the connection of the bank, the number of series groups of capacitors per phase, the number of units in each series group, and the number of units removed from one series group.
Protective monitoring controls are available for capacitor banks connected Wye-Wye, grounded-neutral capacitor banks, and ungrounded-neutral capacitor banks, as shown in figures 1 and 2. This topic is discussed further below in Protection of capacitor Banks. The above scheme applicable to double Wye-configured banks is shown in figure 1.
