We are offering harmonic filter. Today there is trend of increase in power pollution day by day due to more and more use of non-linear equipments such as variable frequency drives, rectifiers, dc drives, induction furnaces and so on. these non-linear loads draw non-sinusoidal current from a sinusoidal voltage source. thus they create current distortion. current distortion can result in voltage distortion and spread the pollution wherever such voltage is supplied. effects of power pollution over voltage / current in the distribution network. over heated power cables due to skin effect and copper and iron loss in transformers, motors and generators. overheating in all types of electronics systems causing components failures. nuisance tripping in circuit breakers and protection relays. malfunction of automatic control systems. damage to capacitors due to resonance. inaccuracy of instrument measurement. interference in telecommunications systems. voltage distortion and lagging in power factor. mitigation of harmonics: there are various equipments to eliminate or control the harmonics. the most advanced technique of elimination of harmonics is by making use of active harmonic filter. active harmonic filter consists of an igbt based switching unit controlled by dsp (digital signal processor) and current sensors to sense load current. functioning of active harmonic filter: it senses the total current in the non-linear load and compensates the harmonic current so that the current drawn from voltage source is sinusoidal. features shunt connection, easy for maintenance easy selection of know parameters; harmonic current. flexible up-grading / redundance. programmable by dsp. selective harmonic elimination. benefits improves power quality, by filtering harmonics. user friendly operation. compensates reactive power. instantaneous dynamic response. adaptative to increase in harmonic current due to additional loads being added. amtechs axpert i-sine active harmonic filter is available from 25a to 1200a harmonic current compensating capacity, in single module. the modules can be paralleled to enhance the capacity.

Voltage drives, The AC Drive which can provide direct high voltage to the motor without any output transformer or filter. Types of Medium Voltage Drive 1. Current Source Inverter 2.
