About
Electrical System Audit
Electrical system audit is a customized Energy Audit that covers the electrical systems. An electrical system audit is the first step to reduce energy cost. An audit explores how efficient your system’s energy performance is ?
It helps you identify areas for improvement. Through an audit, you may find that retrofitting some technologies and improvement in controls of the systems and processes can reduce energy loss and provides a quick payback. Another advantage of an electrical system audit is an understanding of your existing system that your needs in future expansions.
Why Electrical Audit?
Energy audit of an electrical system has a significant importance, as most of the times electric energy holds more than 90 % share of total energy mix. An electrical audit is essentially a first step to reduce your electric energy consumption. A comprehensive electrical system audit indicates how efficient your current processes are ? and identify the areas of improvement ?
Through an electrical energy audit, we find out that with the upgradation of certain machines, equipment, operation controls and training of staff may result into a significant energy savings. In addition to that it evaluates the integrity of electric safety measures and procedures.
Scope of Work of Electrical Audit
Energy Balance of any facility indicates the different types and quantum of energies being used in a facility in different sections, processes etc. E-sankey software is used to visualize the energy flows.
Power quality analysis at power receiving point (Utility company / In house Power Generation), LT Panels, and department wise Distribution Panels. i.e. (Harmonics, Surges, Swells, Current and Voltage Imbalance, Current Leakages, Power Factor, Active, Reactive Power and many more parameters with FLUKE 435 Power quality analyzer.
Thanks to patented Algorithm of Fluke 438, fiscal cost of energy waste due to poor power quality, such as Harmonics, low power factor, resistance of wires, unbalance current, is measured with great accuracy.
Mechanical efficiency of electrical motor can be measured with Fluke 438-II Power Quality and Motor Analyzer. Fluke 435 Series II Power Quality Analyzers. Quickly and easily measure and analyze key electrical and mechanical performance parameters such as power, harmonics, unbalance, motor speed, torque and mechanical power without the need of mechanical sensors.
With the help of thermal imaging camera, we can see what we cant see with naked eyes. Thermal imaging of electrical and mechanical system unveils many hot spots that can be catastrophic in the near future and causing energy loss.
Pumping system analysis includes measurement of water flow rate, pumps electrical power and specific power consumption (kW/m3). Moreover mass flow rate, heat exchanger performance, flow control techniques are evaluated.
Lighting system audit includes lux level survey, lighting control strategy, day light harvesting techniques a of the facility.
Different energy efficiency strategies are evaluated such as use of efficient lights, harvesting daylight, improving the control techniques, integration of smart controls , improvement of lux level for minimum requirement level as per labor laws.
Lighting system design by using simulation software such as Dialux can be done on customer requirement.
In this process, the control systems of all major energy using equipment and processes are evaluated for optimum operational controls. As a result, different energy efficiency measures, such as retrofitting the existing controls, installation of variable frequency drives, automation, process parameters optimization may be the part of action plan.
Chillers and other refrigeration system are evaluated for the energy performance. Energy and mass balance is calculated. Pumps and its controls are evaluated for best performance. The outcomes may be the automation, process control optimization and revision of its design.
Fans and blowers analysis includes air flow measurement (CFM), power consumption, and performance evaluation of the system. Air flow control strategies, ducting design, optimization of air usage and energy conservation opportunities are evaluated. Effectiveness of ventilation system of work space is also evaluated for best performance.
It typically includes the measurement of Range, Approach, Effectiveness, cooling capacity of cooling towers. Water showering, Fills condition, water quality, energy and mass balance is determined. Different energy saving opportunities are identified such as in its control systems, pumping system, and maintenance practices.
It involves ultrasonic testing of motors and pumps bearing for its condition evaluation. Worn out or dry running bearing are the major causes of energy loss and burning of motors
Effective measurement and monitoring is crucial part of energy management system. Existing energy monitoring scheme is evaluated and redesigned if needed.
For the successful implementation of energy efficiency measures and energy management system, training of energy team and relevant staff plays a vital role. In this program, need based, customized training program is executed which comprises of onsite and classroom training session.
