We are a credible Energy Audit Services Provider based in Chennai, Tamil Nadu. Our team of experienced engineers and trained professionals is engaged in rendering these services strictly as per the set industry norms. They measure power, energy and power quality parameters for energy management and power quality improvement to save energy costs, reduce failures and improve productivity. The experts closely work with the clients to under stand their needs in order to offer them the best suited audit packages, that too at market leading rates. Our audit plan is specifically planned with flexible options to suit diversified requirements. We are also engaged in evaluating new energy saving devices and measures. Also, we work to identify potential problems in areas of frequent breakdowns. We keep ourselves updated with the latest advancements in this sector for maximum client satisfaction.

Studies involved :

  • Study at machinery for energy saving potential
  • Study at capacitor banks and various feeder points for PF improvement potential
  • Study at feeders & loads for harmonics and power quality problems
  • Study at incomer to cross check EB meter and analyzer demand and energy billing patterns
  • Study at harmonic filters
  • Identify potential problems in areas of frequent breakdowns

Scope of Energy Study :      

  • We request you to define at the start of the study, locations where the measurements have to take place, parameters to be monitored, interval of logging desired and alarm conditions that need to be monitored
  • We will record all the above mentioned parameters as per your requirement
  • We will submit the data collected as a report in Excel format
  • We also request you to provide us manpower to support our engineers in connections & study

 Basic measurements offered :

  • True RMS Values for Voltage, current and frequency
  • Variation of kW, kVA during the production cycle
  • Energy consumption at feeders and loads w.r.t production
  • Load on/ off / idling time w.r.t energy consumption
  • Demand cross-check at Input
  • PF, kVAR study at Inrush current measurement at Incomers starting from 10 ms
  • Evaluation of energy saving devices
  • Evaluation of modifications on machinery w.r.t energy consumption
  • Distortion PF (PF) and Displacement PF (Cos phi) study
  • Actual KVAR requirement that needed to maintain Unity PF at very efficient level even at distributed levels


Problems  :

  • Harmonics (Voltage & Current) from 1st to 50th & Total Harmonic distortion (THD) on sensitive machinery and non-linear loads that are generating harmonics
  • Evaluation of harmonic filters (if available)  
  • Voltage and current unbalances  
  • K factor (If at Transformers)  
  • Crest factor at sensitive electronic equipment  
  • Neutral current on neutral cables  
  • Voltage Sags & Swells  
  • Waveform pictures & Phasor diagram pictures  
  • harmonics are generated or received at a particular load (using ALM 10/32)
