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.

The Scope Of Electrical System Energy Audit Includes

• Collection of Data – Data collection from Generation, Distribution & Consumption areas.
• Data Analysis & Identify Opportunities – Analyze collected data and derive energy saving opportunities.
• Implementation of identified opportunities – Identified opportunities to be classified in to following categories and technical support to be provided for implementation.
• Specific energy saving calculations.
• Energy monitoring mechanism to track energy conservation.
• Revalidation of cost saving opportunities post implementation.

Benefits Of Detailed Energy Audit In An Organization

• Determination of energy efficiency and performance of electrical and thermal equipment’s and identification all possible energy saving measures to minimize energy consumption.
• About 10-15% of energy cost conservation potential obtained in similar industries based on our experiences.
• Savings from straight implementation without any investment.
• Savings from medium investment with payback.
• Savings from long-term investment with Payback.

Methodology

The methodology that would be adopted by NAVITAS is given below

• Discussion with plant head /field personnel.
• Review and analysis of past performance data.
• Measurements of required parameters using Energy audit instruments.
• Conduct of efficiency and performance improvement trials/tests .
• Discussion of the findings and recommendations with plant personnel.
• Detailed techno economic analysis and Presentation to Management.
• Report submission

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.

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.

Detailed Electrical Safety Audits

• The purpose of Electrical Safety Audit (ESA) is to identify potential electrical hazards and to suggest measures to eliminate the hazards for ensuring safety of personnel and property.
• Electrical hazards continue to threaten safety of people and property in the form of shocks, burns, injury, fire and explosion. With electricity having become an indispensable part of our life, electrical risks are to be managed effectively.
• In an organization, fires due to electrical reasons are very probable, especially in building sectors with more fire loads. In service industries such as information technology, telecommunications, business interruption losses due to electrical hazards (fire in server room, damage of expensive communication equipment, loss of data, fire in cable gallery, etc.) could be substantial.
• Electrical Safety Audit will be carried out considering IS (Indian standard) guidelines, IE (Indian electricity) rules etc. The safety audit carried out by NAVITAS will cover the requirements of Electrical safety & energy conservation.

In order to accomplish the said purpose, the following verifications were made

• Discrepancies with reference to the standard design, construction and O & M practices.
• Adequacy of earthling system and its maintenance, rating of cables, ratings of CB and fuses, Relay and Protection system for the electrical equipment’s.
• Adequacy of the lightning and surge protection system.
• Periodical testing of various electrical components/parameters for proper upkeep of the plant.
• Plant earthing and schematic layout of electrical installations.
• Documents relating to the Statutory Electrical Inspection report, statutory clearance for installation of equipment’s.
• Safety-related work practices adopted by the electrical personnel, use of Personal Protective equipment (PPE), Work Instructions and training given to them.
• Verification of Log book and records for entering the periodical and preventive maintenance tests, break down maintenance and test results.

The location-wise observations/discrepancies noticed during the audit along with recommendations for rectification are furnished in this document with reference to the regulations. Photos, sketches and diagrams are also furnished for reference.

The filled in questionnaire forms and the details of the plant and equipment’s are also furnished in this report.

Objectives Of The Electrical Safety Audit

• Design, Install, implement and maintain facilities which control safety risks.
• Comply with statutory regulations and standards for controlling the risks.
• Train the personnel working at work place for safety aspects, safe behavior and effective use of equipment's to avoid any incident/accident.
• Undertake reviews, analyze, evaluate and install optimum value available safety/ operational equipment's for achieving the accident free operations economically.
• Comply with statutory regulations & regulations.
