1. What is a capacitor bank?

A capacitor bank is a group of electrical capacitors connected together to provide reactive power and improve the power factor of an electrical system.

Why is a capacitor bank used?

It is mainly used to improve power factor, reduce reactive power consumption, reduce electrical losses, and improve the efficiency of electrical systems.

What are the main components of a capacitor bank?

The main components include power capacitors, capacitor contactors, APFC/PFR relay, NH/HRC fuses, fuse bases, CT, detuned reactors, cooling fans, busbars, and panel enclosure.

Do capacitor banks require fuses?

Yes. Properly rated NH/HRC fuse links or other suitable protective devices are normally used to protect individual capacitor steps and the capacitor bank against faults and excessive current.

What is a detuned reactor?

A detuned reactor is connected with capacitors to reduce the risk of harmonic resonance and help protect the capacitor bank in systems with significant harmonic distortion.

Can you supply individual capacitor bank components?

Yes. Individual components such as capacitors, contactors, APFC relays, fuse links, fuse bases, reactors, CTs, and cooling fans can be supplied depending on availability and specification.

CAPACITOR BANK COMPONENTS

Power Capacitors (MPFC capacitors) – Main component that provides reactive power (kVAR). Capacitor Contactors – Switch each capacitor step ON/OFF. HRC/NH Fuse Links + Fuse Bases – Protect each capacitor step against short circuits/overcurrent. APFC/PFR Relay – Measures power factor and automatically controls the capacitor steps. Current Transformer (CT) – Provides load-current information to the APFC relay. Detuned Reactor (if required) – Protects capacitors from harmonics and resonance. Cooling Fans – Remove heat from the capacitor-bank enclosure. Temperature Controller/Thermostat – Controls the cooling fan based on panel temperature. MCB/MCCB/Main Isolator – Main protection and isolation. Busbars & Wiring – Distribute power between the incoming supply and capacitor steps. Panel Enclosure – Houses and protects all components. Indication Lamps / Metering – Shows power, voltage, current, power factor, etc.
