Energy Audits

An Energy audit presents every detail about the building and its components to the owner. Our suggestions detail the effective steps towards implementing a package of improvements to achieve the owner’s goals. These goals could include reducing energy consumption, improving comfort throughout a structure, improving indoor air-quality, eliminating health and safety hazards, or even carbon footprint reduction. 

Primary Objectives of an Energy Audit:

  • The primary goal will be to target utility bill savings and improvement opportunities within the building structure or mechanical systems that have a high-rate of payback and any items which will net a return after a capital expense. The Energy audit shall target basic cost-effective measures for reducing the electrical/gas/water consumption of the building in common and private areas.
  • Suggested upgrades will have an estimated payback calculated by calculations of similar systems and industry standards, or by directly calculating the kWh reduction of the overall assumed schedule of improvements or specifically for a particular given measure or recommendation.
  • Include a review of renewable energy systems potential such as Solar, and Cogeneration.
  • Condition monitoring of equipment
  • Site survey of Energy Consumption
  • Identification of Major energy utilization equipment
  • Identifies minor snags in the System
  • Assessment of energy saving measures
  • Evaluation of operational controls
  • Generate a scope of work and rough pricing estimate for some or all of the suggested improvements.

Benefits of an Energy Audit:

  • Efficiency Analysis & Benchmarking Activity in the site/facility
  • Conducting performance analysis of all Energy Consuming Equipment
  • Definite figures of Consumption of Energy Demands and can forecast future demand based on the present trend
  • Understand the Cost of Energy
  • Management Objectives and Targets can be achieved
  • Reduce costs, Green House Gas emissions and Sustainable Savings into future
  • Helps in Saving Energy Resources for the Future
  • Energy Audit helps in reducing Carbon dioxide Emission from Industries/Facilities
  • Improve business performance, Marketing Opportunities , Enhanced Competitiveness & Improve Public Image
  • Provide savings of Energy Consumption
  • Safe Guard against future legislation

 

Power Quality Audits

Our Power Quality Audits are conducted utilising sophisticated measurement equipment to monitor plant and distribution networks in order to analyse and correctly identify root causes of problematic electrical disturbances.  Only once this is identified, appropriate measures can be recommended to effectively counter the unwanted disturbances.

Typical encounters include transients (impulsive– and oscillatory), short duration variations (interruptions, sags, swells) long-duration variations (undervoltages, overvoltages), voltage imbalances, waveform distortions (DC offset, harmonics, notching, noise), voltage variations (intermittent) and power frequency variations. Class A certified PQ metering equipment are used for all data recordings and measurements.

In the analysis stages, simulation studies are run (including harmonic simulations) in order to optimize a mitigation solution. 

Typical solutions may include filtering techniques (active or passive harmonic filtering), stabilisers or fast compensation/transient free power factor correction or UPS systems.

 

Earth Ground Testing

EML provides earth ground resistance testing for commercial and industrial facilities. Earth testing covers the testing of earth electrodes and the measurement of soil resistivity. The instrument requirements depend on the range of applications.The ability to properly measure ground resistance is essential in preventing costly downtime due to service interruptions caused by poor grounds.

 

Thermography

Thermography is a nondestructive test method that may be used to detect poor connections, unbalanced loads, deteriorated insulation, or other potential problems in energized electrical components. 

These problems may lead to excess power use, increased maintenance costs, or catastrophic equipment failure resulting in unscheduled service interruptions, equipment damage, or other problems. 
 

How Does Thermography Work?

Thermography, also called infrared inspection, is based upon the sensing of heat emitted from the surface of an object in the form of infrared radiation. Test instruments are used to detect and convert the infrared radiation into either a temperature value or a thermal image, which can be used to assess the thermal condition of the object at the time of measurement. An infrared camera is one common type of an infrared thermal imaging device. 
 

How Can Thermography Be Used to Inspect Electrical Equipment?

Energized electrical systems generate heat because of electrical resistance. The amount of heat generated is related to the amount of current flowing through the system and the resistance of the individual system components and connections within the system. As components deteriorate, their resistance increases, causing a localized increase in heat. Similarly, a poorly made connection will have higher resistance than a well-made connection generates excess amount of heat which will lead to the failure of the equipment. Thermography may be used to detect these hot spots and repair them efficiently.
