Harmonics are the distorted waveforms of Current/Voltage Created by
Non –Linear Loads like Variable Speed Drives/Electronic Ballasts/ Computer
power Supplies And any Electyronic Loads with Switch Mode Power Supply and Current Chopping Circuitry.
Impacts of Harmonics
Harmonics waveforms have very high frequencies when compared to the
fundamental waveforms. It , when coincides with the fundamental
Current/Voltage Waveforms, distrots the resutant waveforms.And there by the
True Power Factor (KW/KVA) also distorts.
Harmonic waves forms also
Reduces the Equipment (Motors/Cabes/Transformers etc..)
Life
Increases the Demand
Increases the Equipment Sizes& Cost (Due to Over Heating)
Increase the circuit breakers/relays/Contactors malfunctions
PLC/Microprocessor tripping etc....
What we do?
We exactly study ...
The presence of Harmonics(V&I) THD
Analyse the Individual harmonic level(Upto 50th order)
Analyse the Crest Factor/K-factor
Study the True Power Fcator Level
Impacts Of Harmonics On Transformers
Voltage Unbalance in Network
Voltage Dips/Swells in the Network
Switching Transients & Their Effects
Effects Of Capacitors in Line & Resonance
The Impacts on Maximum Demand
Thermal Impacts of Harmonics on Equipments
Recommendations of Proper Harmonics Mitigation measures
Design and Manufacturing of harmonic filters etc...
