Harmonics are the by-products of modern day power-electronics.
They are created by non-linear loads that draw current in abrupt pulses and generate bad current.
Equipments that generate Harmonics
Variable Frequency Drive (VFD) - Motors
Welding Machines
Equipment with Adjustable Speed Drives
Conveyor Systems
Equipment using SMPS
Battery chargers
UPS Personal Computer
Laptops
Medical Equipments
Symptoms of Harmonics
Overheating in Neutral conductors / Transformers
Nuisance tripping of circuit breakers
Computer malfunctions
Current surges damaging capacitors and fuses
Frequent Motor burning
PLC / PCB components failure
Damage due to Harmonics
Equipment / Production downtime.
Replacement of Motors / Drives.
Production scrap due to communication errors.
Fire Accidents.
Harmonic Analysis Study
Preliminary Harmonic Audit: Identification of improving for Power Quality at area identified at the time of site survey.
Testing & review of harmonics distortion: Providing report to minimize risk of shock hazard, failure of electronic components in the facility.
Data collection consists of close inspection and detailed documentation, using methods including Digital Power analyzers and actual field measurements.
SPIPL will conduct onsite Harmonic Analysis.
SPIPL will then analyze the data collected and prepare the audit report with the solution and submit within a period of 3 weeks.
SPIPL will submit separate proposal (post Audit) for mitigation of Harmonics by installing harmonic suppression equipments with AMC, if required.
