It is preprogrammed to follow the electrical route using GPS module and monitor any illegal connections . Once it detects any illegal connection it operates an inbuilt telescopic extension mounted cutter and terminates the illegal connections. It also monitors the temperature of distribution transformers along with the current drawn from it using thermographic camera and current measuring device. Incase of any abnormalities in temperature or current drawn of the transformer it generates an alarm and conveys it to the local operating station. By the use of such a surveillance system the losses incurred by the power sector can be reduced drastically and also the system prevents detrimental effects arising from transformers.
