General Introduction
The energy metering devices record active and reactive energy consumption. The electricity suppliers generally show the term tan or cos on their bill. Unlike the cos , it is easy to see that the value of tan should be as small as possible in order to have the least reactive energy consumption.
Reactive power compensation gives you the following benefits:
• Savings on electrical equipment, a decrease of the power demand.
• An increase in available power of the supply transformer.
• Lower voltage drops and Watt losses in cables.
• Savings on electricity bills by eliminating reactive energy consumption.
• The reduction of subscribed power KVA (if available)
To compensate for reactive power, it is necessary to provide reactive power by installing compensation equipments instead of taking it from the main distribution. If the value of reactive power to compensate it is small compared to the total apparent power of all the loads (Qc/St<15%), we can choose fixed type compensation equipment. If this value is higher (Qc/St>15%), it is advisable to choose an automatic compensation equipment.
Application & Features
These capacitors are suitable for Three phase power Factor correction where there is Dynamic fluctuation of the load and system Voltage variation is around 20%.
Features of the capacitor:
- Manufactured by using imported hazy BOPP film as main dielectric
- High purity (>99%) Aluminium Foil used as Electrode for high current inrush
- Internal fuse to each element is possible for better safety
- Robust & Highly reliable capacitor performance
- Guaranteed output for a longer period i.e. 10-15 years
