NEW DELHI: With power thefts and outstanding bills continuing to remain a problem area, power distribution company BSES is relying on distribution transformer metering (DT Metering) to cut losses.

Discom sources claim the DT Metering will help BSES zero in on theft prone areas with more accuracy.

"The technology will also help improve energy distribution by load balancing and monitoring quality of power. The initiative involves installing a meter with metering accessories on distribution transformer for the purpose of energy accounting, monitoring supply quality and reliability," sources said.

The process will allow BSES to gauge the level of energy supplied and billed thereby ascertaining the quantum of power theft in the area. Sources said the process of installing DT Meters on the 10,000 distribution transformers is near completion.

The project, which is pegged around Rs. 15 crore, sources said will aid in load survey data of critical parameters and is automatic meter reading (AMR) compatible.

"In the second phase, BSES will connect AMR's with DT Meters. This will then supply real time information to the central BSES control server, eliminating the need for physical data collection," sources informed.

It was mentioned that BSES has became the first discom, complying to the Central Electricity Authority (CEA) guidelines on DT Metering.

Outlining the benefits of the technology sources said: "It helps in control of power theft, by keeping track of the total energy being supplied at the transformer. Any anomaly, by way of power theft is immediately captured. Since a transformer supplies power to a limited number of houses, it greatly narrows down BSES' search to identify the source of the power theft."

Expected to give an added impetus to the discom's efforts to control power theft, DT Metering, sources claimed would enhance energy distribution system by load balancing, providing reliable and division wise input and output data and by identification of clusters where losses are more and by energy auditing.

"DT Metering is part of the BSES's efforts to improve, upgrade and augment the infrastructure and control power theft. In the past four years, we have invested more than Rs. 2700 crore in augmenting and improving infrastructure and adopting news technologies.

AT & C losses in these four years have seen a record reduction in losses," sources claimed.

The discom, which currently depends on voluntary disclosure scheme (VDS), night raids, electrification of unauthorised colonies, use of insulated Aerial Bunched Cables for electrification and deployment of Geographical Information System (GIS) for identifying power theft areas is hopeful that DT Metering will curb power theft considerably.

"Since 2002, BRPL and BYPL have booked over 48,000 case of power theft and booked an electricity load of over 2.8 lakh kW, with DT Metering we are looking forward to bettering that record," sources said.
