Abstract

Apart from causes brought about by the equipment and proper operation of the distribution system , electrical energy may also be lost due to non-technical reasons such as energy theft or pilferage, kilowatt-hour meter tampering, problems on right of way or clearings errors in billing, and inaccurate estimates in loss calculations. They pose problems on distribution systems as their respective contributions to electrical energy loss cannot be quantified easily. A step by step procedure per distribution transformer was developed in this manuscript to address this perplexity. The procedure involved making a current measurement from the secondary side of a distribution transformer and using a load curve to calculate the energy input. The energy output is subtracted from the energy input calculated to come up with total system loss or simply system loss The technical part of the system loss is then isolated to ultimately give the value for non-technical loss. The results can be used to determine priority distribution transformers when implementing activities or projects which targets non-technical loss reduction.
