At Encon Engineers, our specialization that evolved in 1995 on
Sustainable Power Quality Solution and Harmonic Distortion Correction
with emphasis on Total Power Management for enhanced Productivity and
Product Quality; today serves several hundred corporates across the
length and breadth of India and worldwide. Our integrity and pride come
from the fact that over 80% of our past clients come back to us with
repeat orders. A distinct convention has been evolved, through decades
of our performance from over 500 projects with over 350 clients, and an
ever-increasing number of corporates are benchmarking their plant's 3P,
Power, Productivity, and Profitability on the lines of Encon's Total
Power Quality and Harmonic Solutions.
We integrate all your energy components as like seeing the complete
elephant that Troubleshoot equipment tripping, failures, debottleneck
capacity limitation, enhance product quality and slash energy
consumptions by comprehensively mitigating all of your power quality
harmonics problems which arise out of the harmonic distortions of the
fundamental waveform. We help you to reduce both with your Capex
(project investment cost) and Opex (running electricity bill and
maintenance cost by minimizing equipment failures), an Encon line of
concept of 3P, Power, Productivity, and Profitability that would
catapult your plant at the top of the competition chain.
How Passive Harmonic Filter prevents equipment failure from harmonic flow?
1. Harmonic being a Current Source, flows in the opposite direction of normal power flow.
Harmonics flow from the downstream non-linear-loads into all branches
of the upstream power system wherein it distributes in inverse
proportion to the respective electrical branch impedance.
2. By Ohm’s Law, the harmonic current flows across all feeder paths
of an electrical power system based on each path’s relative impedance. Along the harmonic flow path, two events happen.
3. First, the downstream equipment and cables, designed for a
fundamental frequency of 50/ 60Hz, absorb these high-frequency harmonic
currents, which cause excessive stress to themselves. It
results in equipment failure, high drive temp, unwanted tripping and
malfunction of sensitive equipment. When harmonics are excessive, only a
super tuned passive harmonic filter can effectively solve these
harmonic problems. The super tuning creates a strong short-circuit path
and diverts the excessive harmonic current away from the downstream
loads into itself. It then nullifies and thus eliminates the harmonic
current within the three-phase passive harmonic filter.
4. Second, the grid being relatively a lower impedance path, absorbs the remaining leftover harmonics after
the absorption by the downstream equipment and machinery. A harmonic
filter, either an active filter or a passive harmonic filter, prevents
these harmonics from going over to the upstream grid.
