Energy Audit Service

Doksun Power Pvt ltd is a Certified ISO 9001:2015 (Quality Management System) ISO 14001:2015 (Environment Management System) ISO 45001:2018 (Occupational Health & Safety Management System) Energy Audit service provider. An Energy Audit is a plant site survey, involving measurements and analyses of energy and material flows in an industrial plant or building, with the objective of understanding the energy dynamics of the system. Typically an energy audit is conducted to identify opportunities to reduce the energy demand of the system without affecting production volumes, quality or safety. The Energy Audit provides the vital information base for overall energy conservation program covering essentially energy utilization analysis and evaluation of energy conservation measures.

Touch Potential Calculations

Electrical potential differences are variances between spaces where electricity will discharge in a non-uniform manner. The difference in the electrical potentials in a given area can present safety threats and as a result form fundamental performance criteria in electrical earthing systems. “Touch potential” is a way of measuring the threat to life if someone is in contact with a structure during an electrical fault. Codes of practice and standards prescribe tolerable exposure levels for “touch potential” and Doksun Power engineers can assess whether a given area meets performance guidelines. As with each of these services, please feel free to refer to the service specific page for more information, or contact a member of our team.

Step Potential Calculations

Step potentials share their concept with touch potentials, only in this instance instead of measuring the prospective electrical potential difference when physically touching a structure during a fault, it instead defines the difference in electrical potentials between someone’s feet. As electricity disperses into the earth the volume and intensity degrades and as such so does its apparent threat to life. The rate of notional decay relates to the ground’s resistance to electrical current. Even over very short distances, such as that between the feet of a person, electricity could degrade considerably, and the quantity of degradation will determine the apparent threat to life.

Soil Resistivity Surveys

This service helps determine how the ground will be able to dissipate electrical current, which will ultimately dictate the attributes of the system required to safely manage fault current. The process of undertaking a soil resistivity survey involves Doksun Power engineers travelling to site where they will use testing instrumentation, such as the Megger DET 2/2, in combination with proprietary testing leads to take measurements of electrical resistivity performance. The measurements are taken at a range of distances, and sometimes in a range of areas. The data set is then processed through CDEGS software

Soil Modelling and Analysis

A soil model, or sometimes referred to as a ground profile, is obtained by processing soil resistivity testing data (see above or on the dedicated service page for soil resistivity surveys) through industry leading CDEGS software, which enables Doksun Power engineers to assess the ways in which the mass of earth in the survey area will disperse electrical current.

Rise of Earth Potential Studies – ROEP, EPR, or GPR

We all work and live in places which depend upon the National Grid for the supply of electricity. The way that the National Grid transmits this electrical energy is through a network of transmission towers, power lines, substations and switch yards. In the event that there is a fault electrical surge in that network it is quite possible that the fault electrical current is going to cause problems until it discharges into the ground. When fault current hits an electrical earthing system the earth system’s inherent electrical resistance will result in a calculable voltage difference which then radiates into the system and surrounding mass of earth. If the system’s performance results in a high Earth Potential Rise (EPR) / Rise of Earth Potential (ROEP) /Ground Potential Rise (GPR) then the consequences could be disastrous and that’s why numerous customers find their way to Doksun power’s respected technical team.

Electrical Earthing – Grounding Systems

In the event of fault electrical current being transmitted to a site, facility, or piece of infrastructure, these systems are expected to manage fault electrical current. The usefulness of them is dependent upon their capacity to safely discharge electrical current. The best way to ensure that an effective, safe, and robust electrical earthing system is specified is to contact the Doksun Power Technical Department and find out how the team can help.

Electrical Earthing – System Design

Electrical earthing / grounding systems should be designed by trained engineers who have the ability to specify what variety and configuration of components will be required to achieve the performance criteria governed by client requirements, codes of practice, and standards. The CDEGS software packages used to develop electrical earthing designs enable our engineers to simulate a range of fault electrical current conditions and as such theoretically test the safety system before it is installed. Doksun Power engineers are focused on developing the most practical, time saving, and financially economical electrical earthing system to ensure that their clients achieve the best value system possible.

Electrical Earthing System Testing

This service should be undertaken upon installation completion, at times of system modification, or periodically to assess ongoing performance of electrical earthing systems. Doksun Power has the capacity to test substantial power stations, solar farm installations, substations, and many other varieties of electrical earthing systems and the company’s engineers are often found certifying systems.

Fault Distribution Analysis & Modelling

The capacity to predict how fault electrical current will behave is essential when working on any construction project as this means that one of the most dangerous anomalies that faces it can be safely managed.

Audits, Testing and Commissioning

Electrical earthing systems are often regarded as grim necessity that is usually not well understood and frequently undervalued. The capacity to walk onto a site and determine how effective the electrical earthing provision is, or indeed, to identify problems that others cannot determine is an attribute for which Doksun Power engineers are regularly praised. Doksun Power engineers regularly audit construction works to ensure that every opportunity has been actualized to improve electrical earthing performance and this can include testing a system at appropriate intervals.
