11. Network Layered with Satellite Image

12. Network Tracing and Breakdown Analysis Network Tracing • Trace network assets in forward and backward • The following are the key functions: • Display of connectivity from the asset to source of supply • Number of consumers connected to • Transformer (DTR) and feeder • Pole • Line length of conductor en-route tracing of electrical entities • Differentiation of DTR’s secondary network (LT Line) • Breakdown Analysis • Works on ‘What If Analysis’ model i.e. what happens if there is a breakdown in LT Network, HT Network & DTR. • Gives the complete lists of affected consumers incase of network break at a particular network asset. • Display of Affected Network • Display of Affected Consumers

13. SLD - DTR

14. Trouble Call Management (TCM) • Manages Complaint Registration and Complaint • Dispatch functions. • Following are the key functions of TCM: • Registration of consumer complaints • Dispatching to field staff with reference to location • Tracks the status of complaint with attended information • Statistical reports on turn around times & type of complaint
