Distribution Transformer Alarm

Transformers form the lifeblood of any supply authority installation and is therefore considered a fundamental element of the network topography and overall electricity distribution design. It is therefore essential to manage these devices within their specifications to ensure longevity as well as to derive maximum benefit in terms of revenue generation, whilst ensuring an acceptable return on investment.

This return on investments is quantified by the revenue generated from the transformer capacity less the overall total losses delivered in kilowatt-hours to the paying customer, and not necessarily the consumer.

Notwithstanding the normal technical challenges supply authorities encounter in dealing with technical losses, a significant and growing challenge supply authorities are experiencing more and more is the rise in the undesired Non-Technical losses, which contributes to the overall loss equation.

These Non-Technical losses in distribution transformers are specifically related to:

• The theft of units due to its high concentration of copper in the windings
• Theft for illicit re-sale
• The theft of Oil for various reasons, and
• Illegal connections
