We manufacture and provide harmonic filters which as the name imply filters harmonic waves. Harmonics are sinusoidal wave forms with frequency multiples of fundamental frequency. Such frequency is formed by equipment using frequency conversion technology and also due to power drawing pattern of non- linker loads. Some sources of harmonic filters include the following:

• Invertors
• Rectifiers
• D.C machines
• ARC furnaces
• Automatic welding machines
• Uninterrupted power supplies
• Switch mode power supply
• Power Transformers
• Variable speed drives
• Medium frequency induction furnaces

It is imperative to record power parameters and conduct harmonic study in order to provide correct solution for the P.F. improvement and harmonic filtration. We design our harmonic filters as per the level of harmonics. Our harmonic protection filters are used for improvement of power factor and part elimination of harmonics. Harmonic filters are manufactured using reactors and capacitors, ideally detuned. Our range is ideal when distortion is 15 to 40 %.
 
Advantages:

• Improve power factor
• Avoid harmonic amplification in the system
• Protect capacitors from Harmonic overloading
• Eliminate 20 to 50 % predominate Harmonics

Our system can be configured to operate in fully automatic mode. The common objective is to eliminate high level of harmonic currents to acceptable level to comply with utility regulations. They provide traps for individual harmonic frequencies and provide reactive power compensation at fundamental frequency. Some benefits of our harmony filter comprises of the following:

• Reduction in Harmonic Distortion
• Reduction in line losses
• Elimination of power factor penalty
• Release of Additional VA capacity in the system
• Improvement in voltage profile
• Improvement in system reliability
• Improvement in overall power quality
• Improvement in Reduction in Energy bill
• Improvement in life of Electrical Equipment

We offer harmonic filters which are widely used for personal computers. As PCs use non-linear current which is not in linear relation with voltage applied. When a sinusoidal voltage is applied, an ideal linear load should draw sinusoidal current. PC draws current for a very short period during every half cycle.
 
Due to harmonics utility of the power source is reduced, lot of power is wasted and problems like neutral over heating, high neutral to ground voltage, nuisance operation of trip circuits and harmonic interference arises. A good harmonic filter reduces the harmonics to less than 5% and overcomes all the problems related to it. Some of the advantages of our active harmonic filters include the following:

• Better system stability
• Improved usage of Power Source
• Reduced Power Wastage
• Elimination of problems due to harmonics
• Reduced nuisance operation of circuit protecting elements such as fuses, CBs etc

Our battery chargers find their applications in varied areas owing to their technical excellence. Our chargers are used to put energy into a cell or battery by forcing electric current into the device. Based on the latest technology our range ensures longer life and flawless operation.
 

We manufacture and supply optimum quality of energy saving equipment which is used widely for power conservation. Our range is ideal for pure lighting and mixed load and comprises of fluorescent tubes, CFL, high vapour sodium & mercury lamps and other discharge lamps and window or split air-conditioners, raw plug connected office equipment such as computers, fans, exhaust fans and many more. Some of the advantages of our equipment encompass the following:

• Extended life of luminaries
• Reduction in temperature in control gears
• Savings of 15-25% in lighting load and 12-18% in mixed load
• Centrally installed and maintenance life of more than 15 years
• No effect on any other parameters of the load
• Payback below 24 months

Our power transformers are designed to withstand adverse site conditions and offer trouble free service. Our technologically advanced power transformers are capable of accepting energy at one voltage and then delivering it to the other voltage. This ensures electrical energy generated at relatively low voltage and transmitted at high voltage and low current. This also helps in minimizing losses and enabling the equipment to operate at safe voltage. Some of the salient features of our power transformers include the following:

• Low maintenance
• High performance
• Technically superior

 Applications:

• Aerospace application
• Oil and dry type units
• Utility applications
• Commercial and industrial power distribution system

We manufacture and provide optimum quality constant voltage transformers (CVT) in which the AC mains powers the input winding, which in turn is widely separated physically from the isolated output winding. Very moderate flux linkage levels are maintained in input winding running. The output winding has an intrinsic energy storage characteristic. This characteristic operates in conjunction with mains capacitor to produce self-generated AC flux field with is indirectly excited from the input winding. Some of the salient features of our CVT include the following:

• Limiting of Intense current and protection short circuit
• Energy storage for line lose up to main 3ms at typical load
• Short term over load capacity
• No use of feed back control
• No use of any semiconductor or moving part offering very high reliability
• Higher input voltage control range for load less than rated low

Our AC reactors are used for AC drive. Manufactured using latest technology our reactors are installed in the output end of the converter for restraining the capacitive charge current of the cable that connects the converter and the electric machine and for passivating the voltage climbing of the PWM wave.
