SYNOPSIS

This presentation will focus on: Mitigating Harmonics in HVAC and Electrical Systems – One of the most misunderstood design elements in an HVAC building is the role Harmonics play in the electrical system. Harmonics are harmful, energy-wasting currents which flow in the electrical system.
Harmonic Distortion - A by product of modern electronics, occurs when large numbers of personal computers, uninterruptible power supplies (UPS), variable-frequency drives (VFDs), and other devices using solid-state power-switching supplies to convert (AC) power to (DC) power are present.
In HVAC systems - Harmonic in the power supply can raise the temperature of electrical equipment and therefore inhibit performance, as a result of the increased application of high-speed switching equipment, this has become an increasing problem. Let us make our electrical system clean power and further improve building efficiency.

The presentation will further touch on:
    Fundamentals of “Harmonics”
    The Ideal vs. Distorted Waveform
    Definition of Harmonics
    Calculation of THiD
    Harmonic Producing Loads
    Standards and Recommendations
    Harmonic Mitigation Techniques & Software Tools
