Harmonic Analysis / Power Audits


  • 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.
