From the Desk of Managing DirectorOur ValuesA popular speaker started off a seminar by holding up a Rs 500 note. A crowd of 200 had gathered to hear him speak. He asked, “Who would like this Rs 500 note?” 200 hands went up.He said, “I am going to give this Rs 500 note to one of you but first, let me do this.” He crumpled the currency note up. He then asked, “Who still wants it?” All 200 hands were still raised.“Well,” he replied, “What if I do this?” Then he dropped the currency note on the ground and stomped on it with his shoes.
He picked it up, and showed it to the crowd. The currency note was all crumpled and dirty.“Now who still wants it?” All the hands still went up.“My friends, I have just showed you a very important lesson. No matter what I did to the money, you still wanted it because it did not decrease in value. It was still worth Rs 500. Many times in our lives, life crumples us and grinds us into the dirt. We make bad decisions or deal with poor circumstances. We feel worthless. But no matter what has happened or what will happen, We will never lose our value. We are special – Don’t ever forget it!”

TECHNO-TALK
In simple terms, harmonics are extra frequencies that when present in an electrical circuit, distort the AC sine wave. A harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency.For example, if the fundamental frequency is f, the harmonics have frequencies 2f, 3f, 4f, . . . etc. Harmonic frequencies are equally spaced by the width of the fundamental frequency and can be found by repeatedly adding that frequency. In India, the fundamental frequency of electric supply is 50 Hz. The frequencies of the harmonics are 100 Hz, 150 Hz, 200 Hz, 250 Hz, 300 Hz, 350 Hz and so on. 150 Hz is called the 'third' harmonic (3 x 50 Hz), 250 Hz is called the 'fifth' harmonic (5 x 50 Hz), etc. The presence of harmonics in an electrical system distorts the clean shape of a sine wave.How do you know if you have harmonics in your electrical system?If you occasionally experience some unexplained occurrences such as flickering lights, alarms going off, or MCB's, MCCB's, RCD's and Earth Leakage devices tripping for no apparent reason, you are most likely experiencing harmonics in your electrical environment. Other signs are cables running hot, hot switchboards or overheating motors. If you are replacing your motor's bearings & insulation often, that's a strong indication of the presence of harmonics.What are the effects of harmonics in your electrical system?Harmonics are very harmful within an electrical system and can have serious consequences. For example, the presence of harmonics reduces the life of equipment. It is possible that the investment that you made in your motors & drives will not be realized if they are damaged and need replacing before their expected life span. This can be very expensive.Harmonics cause things to run hot, which cause stress on the cables and equipment. In the long term, this degrades an electrical system. The presence of harmonics will also mean that although you will get billed for the power that you are supplied, a large percentage of that power may be unusable. Harmonic mitigation is taking action to minimize the presence of harmonics in your electrical system and can achieve great cost savings.
WHAT IS HARMONIC MITIGATION?
Different types of Harmonic Mitigation devices at input (line) side of VSD (VFD)Line ReactorsAlso known as Inductors, Chokes & Line Filters.For use on the input of a VSD / Inverter or other non-linear devices.Virtually eliminate nuisance tripping.Extend life of semiconductors.Reduce harmonic distortion.Reduce surge currents.Improve true power factor.Passive Harmonic FiltersAlso known as 'Low Pass Filters'.For reducing harmonics at the VSD / Inverter or other non-
linear devices.Reduction of harmonics to 5-6%Reduce cable heating and line losses.Improve power factor and reduce system loss.Minimize interference with other equipment.Improved system voltage/current waveform.Prevent nuisance tripping of fuse and circuit breakers.Meets the IEEE519 Standard.Active Harmonic FiltersMainly used for group harmonic compensation at the main switchboard.Reduction of harmonics to 5% or less.Reactive current control.Load side transient suppression.Load side surge suppression. Reduction of supply sags and surges.Improves electrical system efficiency.Reduces operations and maintenance costs.Meets the IEEE519 Standard.
Output (load) side of VSD (VFD) Load ReactorsAlso known as Motor Chokes, Load Filters & Inductors.For use on the output of a VSD / Inverter or other non-linear devices.Protect motors from long lead effects.Reduce reflective currents.Reduce harmonic distortion.Reduce surge currents.Reduce motor temperature.Reduce motor audible noise.dV/dt FiltersdV/dt filters are designed to protect AC motors from the destructive effects of long lead peak voltages.Increase bearing life and up-time.Reduce common mode noise and currents.Prevent voltage spikes from exceeding 1 kV.Reduction in motor peak voltages.Protection of motor insulation.Reduction of motor temperature.Sine Wave FiltersIn addition to protecting the motor, the sine-wave filter also provides protection for the VSD / Inverter.Unshielded motor cables can be used, lower project costs.Motor operating life is increased.Longer motor cables possible.Significantly lower eddy current and stray flux losses.Significant reduction of bearing currents.Eliminate torque ripple.Eliminate voltage wave reflection.Reduces motor noise, vibration and heat.
