Harmonics Study

Harmonics are the distorted waveforms of Current/Voltage Created by Non –Linear Loads like Variable Speed Drives/Electronic Ballasts/ Computer power Supplies and any Electronic Load with Switch Mode Power Supply & Current Chopping Circuitry.

Harmonics Study

Harmonics waveforms have very high frequencies when compared to the fundamental waveforms. It , when super imposess on the fundamental Current/Voltage Waveforms, distorts the resultant waveforms.And there by the True Power Factor (KW/KVA) also distorts.

This results in REDUCTION in(useful)Active Power, which does the actual work , and INCREASE in Wattless (Waste)Power. Which results in INCREASED
( I²R) Lossess & Cable and Equipment Heat.

Harmonic Waveforms also …

  • Reduces the Equipment (Motors/Cables/Transformers etc..) Life

  • Increases the Demand

  • Increases the Equipment Size & Cost of Installation

  • Increases the circuit breakers/relays/Contactors malfunctioning

  • PLC/Microprocessor tripping etc....

  • Increased Down Time & Reduced Productivity

  • What We do..?

    We exactly study ...
