Distribution Transformation Management System (DTMS) is meant for the energy audit at Power Distribution Transformer. At the Transformer level, a 3-phase meter is placed and it measures how much power is being distributed to the consumers (Domestic, Commercial, Agricultural, etc.). For every 15minutes, the 3-phase meter sends the ‘power distribution’ information to the DC and the meters placed at the consumer end also send the consumption information to the DC. After receiving the data from the meters, energy audit takes place.
