Electrical Energy Audit
How your plant takes and uses its electricity: transformer loading, distribution, power factor and the load on each phase, logged over 24 to 48 hours.
About this audit
Where the Power Goes, and Where It Is Lost
An electrical energy audit follows the power from the incoming supply, through the transformers and distribution boards, to the machines that use it. The aim is to find the electrical bottlenecks, and the causes of penalties on the electricity bill, so that you can decide what to put right.
The audit is carried out by Vinoth Electricals, engineers, consultants and contractors for 40 years (EA licence No. 2577). You send the enquiry to Ram Engineering, and we arrange it.
Carried out by
What the Audit Checks
- Transformer loading: how heavily each transformer is loaded, and at what times of day
- Distribution efficiency: the boards, feeders and cables between the transformers and the machines
- Power factor: whether the plant draws enough reactive current to bring a penalty on the bill
- Load profiling: the load on each phase, logged over 24 to 48 hours
Why it matters
What the Measurements Show
A transformer that runs close to its rating for long hours runs hot and leaves little room for new machines. One that runs lightly loaded all day still has its own fixed losses. A log of the load shows which you have, and when.
Power factor tells you how much of the current drawn does useful work. Induction motors, especially lightly loaded ones, also draw reactive current, which loads the cables and transformers without turning a shaft. Many electricity tariffs penalise a low power factor; your bill shows whether yours does.
The three phases seldom carry equal loads. A large imbalance adds to the losses and can heat three-phase motors, and it shows only when each phase is logged.
Loads change from shift to shift and from day to day, so one reading can mislead. Logging over 24 to 48 hours catches the peaks and the quiet hours.
What You Get
A picture of how your plant draws its power, from the incoming supply to the main loads, with the findings that point to electrical bottlenecks and to power factor penalties.
The audit does not promise a saving. It shows where the power goes and what each finding points to; what is worth correcting is your decision.
Questions About the Electrical Energy Audit
Who carries out the audit?
Vinoth Electricals, engineers, consultants and contractors for 40 years (EA licence No. 2577). Send your enquiry to Ram Engineering and we arrange the audit with them.
Why log the load for 24 to 48 hours?
Because a plant’s load changes across shifts and between days. A log over one or two days records the peaks and the quiet hours that a single reading would miss.
Will the audit tell us how much we will save?
We do not quote a saving in advance. The audit shows how the power is used and where it is lost; any saving depends on what is corrected, and is measured afterwards at your own plant.
Can we book it with the other plant audits?
Yes. Book it on its own, or together with the power quality and harmonic analysis or any of the other plant audits.
