A harmonic is defined as one of the components obtained from the breakdown of a periodic wave in the Fourier series. The order of a harmonic is further defined as the ratio between the frequency of the harmonic and the fundamental frequency of the periodic wave considered.
Negative Effects of Harmonics :
v The capacitors are subjected to a voltage overload and their lifetime is drastically reduced.
v Connection of the capacitor causes a large increase in the voltage distortion factor THD(V) & THD (I).
v Reduced motor life, inability to fully load motor.
v The user transformers, wires and loads are affected by this increase in current.
v This reduces the capacity of transformer resulting into economic loss as well.
v High voltage distortion shall also be encountered when shifting from mains to emergency generator.
v Large current in neutral wires of power distribution system.
How to Control the HARMONICS :
v Floor mounting series for medium to large industries.
v Available from 125 to 1000 KVAr rating.
v Advanced 3 Ph. controller with inbuilt Load Analyzer.
v 3 Phase Energy Analyzer with Data Logger (Optional)
v 3 CT as single CT input for controller.
v Auto Manual selection through Selector Switch
v Axial Flow/Centrifugal Fan controlled through thermostat.
v Upto 3 years Warranty with Long Life LL-10 Capacitors
