What Do P.F. Correction Capacitors Have To Do With Harmonics?

In an industrial plant containing power factor correction capacitors, harmonics distortions can be magnified due to the interaction between the capacitors and the service transformer. This is referred to as harmonic resonance or parallel resonance. Often, harmonic-related problems do not show up until capacitors are applied for power factor correction.

Data Logger Module with Energy Analyzer (Optional)
Energy analyzer with data logger is having facility to record and display all the 3 phase parameters of mains where P.F.C. systems in connected

Capacitors Banks
We deal in the Neptune–Ducati company’s range of capacitor banks, which use capacitor modules from M/s Ducati energia s.p.a, Italy. Due to the technological innovation of self–heating metallized polypropylene, the rated power of 50 KVAR is achieved in just one 3 phase element with very compact dimensions and a much higher life expectancy in comparison with other models. These new long-life capacitors Mono16 and Modulo50 reach an expected life of more than 160,000 hours and a size reduction upto 40% against the technologies so far applied with low loss of 0.2W/KVAR, with 4 in capabilities and oil impregnation, the performance of these capacitors are much better in comparison to other technologies available in market like gas filled and dry type.

Harmonic Reactors
Neptune Filter Circuits are designed as three-phase reactors with an iron core and air gap. Harmonic Filter Reactors are made out of high quality material and very stringent quality control. It has properties like low temperature rise and lower flux density so that it can operate in worst conditions of ambient and harmonic overloads. These offer very good degree of linearity and low losses. Cheaper and non-linear reactors may trigger undesirable chain phenomena during period of operation with high harmonic values, such as reduction in the inductance with consequent increase in the resonance frequency of the LC group, which would drain off more harmonic current, further reducing its inductance and overload the reactor more and more. Reactors are available with filtering factor of 5.6%, 7% and 14% as per standard ratings. Any other filtering factor and rating can be developed on request.
