System Design for Prevention of Electricity Theft

Abstract

This paper describes the effective system developed for
the prevention of Electric Power theft caused by direct
rigging. The approach used is to make the electricity
useless at distribution transformers and to restore the
electricity to useful form by passing it through modified
Energy Meter which is exclusively responsible for
providing useful electricity to genuine consumers. This
can be achieved by stepping up voltage by a factor
‘k’(where k=2, 3, 4 ) on low tension side of distribution
transformer for short duration in each periodic interval
with the help of circuit developed at transformer side.
This rough form of voltage if used by direct rigging on
electric power conductor, would cause the damage to the
appliances. While the genuine consumer gets this supply
through modified Energy Meter, which has the ability to
detect this rough voltage waveform and convert it back to
normal voltage. In this way one of the major causes of
electricity theft can be controlled by very economical,
simple and technical approach. This circuit has much
flexibility in the design so it is less probable to develop a
remedy to bypass this design for pilfering.
