Background:
Harmonics in Electrical Networks.

The harmonic is defined as one of the components obtained from the breakdown of a periodic wave in the flourier 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.

In the case of the perfectly sinusoidal waveform (as should characterize the voltage supplied by the utility) only the fundamental harmonic of the first order will be present, which in India has a frequency of 50 Hz.

If a sinusoidal voltage is applied to a load, the circulating current will also have a sinusoidal waveform only in the presence of loads with "linear characteristics".

In the presence of a "non-linear" load the current waveform will deviate from the ideal pattern and breaking down the wave according to the flourier theorem will show evidence of harmonics whose number and amplitude will increase with the degree of distortion in the current waveform.

The increasingly frequent use of non-linear loads in industrial facilities (inverters, fluorescent lamps, welders, DC drives etc.) Creates elevated distortions in the waveform of circulating current.

This is true in the case of ac/dc converters, for which the input current theoretically displays only harmonics of the order.

h = mp +- 1.

The parameter used ot determine the level of harmonic distortion presents in an electrical network is THD% of voltage and current.

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. It is important to note that capacitors themselves are not main cause of harmonics, but only aggravate potential harmonic problems. Often, harmonic-related problems do not show up until capacitors are applied for power factor correction.

Capacitors Banks:
Neptune-Ducati ranges of Capacitor Banks are using Capacitor Modules from M/s Ducati energia s.p.a, Italy. Ducati energia is a leading company in production of power factor correction capacitors. Following this tradition, continuous investments in research and development of new products have represented the policy of the company.

The result of this philosophy is the new range of Long Life Capacitors MON016 and MODUL050. Thanks to the technological innovation of self-healing metallized polypropylene; the rated power of 50 KVAR is achieved in just one 3-phase element with very compact dimensions & a much higher life expectancy in comparison with other models. These new Long-Life Capacitors Mono16 & Modul050 reach an expected life of more than 150,000 hours and a size reduction up to 40% against the technologies so far applied with low loss of O.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 & 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 been designed with properties like low temperature rise and lower flux density so that it can operate in worst conditions of ambient and harmonic overloads. They offer very good degree of linearity and low losses. Cheaper and non-ÃƒÆ’Ã¢â‚¬Å¡Ãƒâ€šÃ‚Âlinear reactors may trigger undesirable chain phenomena during periods 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.

Other parts of Detuned systems:
a) Heavy DutyTP Contactors for switching
b) HRC Fuses
c) ACB and MCCB as Incomer
