Detailed Energy Auditing

Detailed Energy Audit is a comprehensive audit and results in a detailed energy project implementation plan for a facility, since it accounts for the energy use of all major equipments. It considers the interactive effects of various benchmark projects and offers the most accurate estimate of energy savings and cost.It includes detailed energy cost saving calculations and project implementation costs.

What is Energy Auditing? 

Energy Auditing means the verification, monitoring and analysis of use of energy, including submission of technical reports containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce the energy consumption of an organization.

Need for Energy Audit in an Organization

  • In any organization the three top operating expenses are energy (both electrical and thermal), Labour and materials.
  • Energy would emerge as a top ranker for cost reduction.
  • The Primary objective of Energy Audit is to determine ways to reduce energy consumption per unit of product output or to lower operating costs.
  • Energy Audit provides a “bench-mark” for managing energy in the organization.

Harmonics Analyzing & Solutions

What is Harmonics?

Harmonics are multiples of the fundamental frequency of an electrical power system.

  • For example, the fundamental frequency is 50 Hz, and then the 5th harmonic is five times that frequency, or 250 .Hz.
  • The substantial increase of electronic devices in an electrical distribution system causes Harmonics in Electrical System.

Harmonics are a growing concern in the management of electrical systems today. Power electronic devices have become abundant nowadays due to their capabilities for precise process control and energy savings benefits. However, they also bring drawbacks to electrical distribution systems. The presence of harmonics in electrical systems means that current and voltage are distorted and deviate from sinusoidal waveforms.

Scope Of Harmonics Analysis

  • Analyze level of harmonics at MAIN PANEL all feeders during regular & peak load condition.
  • Analysis includes determination of THD (Total Harmonic Distortion).
  • A report will be created based on the above analysis for each feeder identified for analyzing the harmonic values.
  • Harmonics Analyzing kit with a meter will measures Total Harmonic Distortion at any given point – Both Voltage and Current [THD].
  • Simultaneously the kit will measure the breakup of THD in 3rd, 5th, 7th, 9th, 11th, 13th, 15th, up to 63rd.
  • In most of the cases, the harmonics level shall be falling within the above range. In case, the levels of harmonics are higher, additional meters shall be added to determine which other level of harmonics is predominant.
  • Shall also measure the various instantaneous parameters at that point of time including the below which we could use for analyzing purposes and determine the quality of power.

After Analyzing Of Harmonics In The Electrical Systems

A complete report will be generated based on the above parameters with time stamp.

We propose to take samples of the above instantaneous values for required intervals at each feeder during the peak load periods.

Once we understand the pattern of harmonics in the specified feeder, we will analyze the output to determine if filters are required to reduce the level of harmonics.

Harmonics are a growing concern in the management of electrical systems today. Designers are requested to pay more and more attention to energy savings and improved availability of electricity. But there is still a need for more explanation, in order to dissipate confusion and misinterpretation. Power electronic devices have become abundant nowadays due to their capabilities for precise process control and energy savings benefits. However, they also bring drawbacks to electrical distribution systems. The presence of harmonics in electrical systems means that current and voltage are distorted and deviate fromd sinusoidal waveforms.

Power Quality Analysis

Power quality determines the fitness of electrical power to consumer devices. Synchronization of the voltage frequency and phase allows electrical systems to function in their intended manner without significant loss of performance or life.

In its broadest sense, power quality is a set of boundaries that allows electrical systems to function in their intended manner without significant loss of performance or life. The term is used to describe electric power that drives an electrical device and the device’s ability to function properly with that electric power. Without the proper power, an electrical device may malfunction, fail prematurely or not operate at all. There are many ways in which electric power can be of poor quality and many more causes of such poor-quality power.

Our highly experienced electrical team will undertake survey and analyze the electrical installations, for the purpose of establishing the quality of the supplies. Using the suitable equipment, we will able to identify potential issues with the power quality and reduce your energy losses.
