How to be ensure whether to go for Harmonics analysis for your plant or not ?

Which Equipment is responsible for harmonics generation?

Harmonics are the by-products of Modern facilities and Electronic equipment. These are often called non-linear loads.

• ? Adjustable Speed AC and DC Variable speed motor drives
• ? Controlled Rectifiers, Battery Chargers, Uninterrupted Power Supply (UPS) systems
• ? Phase controlled AC voltage regulators
• ? Arc Furnaces or Induction Furnaces, Welding Machines
• ? PLC, DCS and SCADA systems (SMPS)
• ? Solid State Heater Controls
• ? HVDC sending and receiving end equipment

Effect of Harmonics:

• ? Overheating of Generator, motor, transformer.
• ? Overvoltage conditions on supply system.
• ? Increased transformer losses (need to over-size)
• ? Nuisance tripping of circuit breakers
• ? Improper operation of microprocessor-based equipment
• ? Overheating and possible resonance with capacitors
• ? Re-injection of harmonic currents into the utility network.
• ? Neutral burnout.
• ? Insulation breakdown.
• ? Decreasing Distribution Capacity due to hot cables.

But every study comes at a cost, so how to ensure whether your plant should go for Harmonic analysis of or not.
