Electrical power theft is a major problem in power system network all over the world,which
is illegal and should be strictly prohibited. Power theft can be defined as the usage of the
electrical power without any contract with the supplier. In order to eliminate power theft, the
location of power theft is to be known so that appropriate action will be taken on the legal
offenders. The circuit consists of Arduino, GSM, LCD,ESP module and Current transformers.
Meters can not be used for high currents so current sensing is done by current transformers.
Two CT's are used,one is connected at load side to measure the current through load and
other CT is connected at supply terminals to measure the current supplied by source.Using
IoT,power theft detect or kit has been implemented and the same also done using GSM for
the purpose of back up protection.
