    • 18. Smart Grid at Dehradun Campus • First phase of Smart Grid has been implemented at our Dehradun Campus in collaboration with BSES Yamuna Power Limited • The Phase - I of the project involves incorporation of Modular Integrated Distribution Automation System (MIDAS) which is automation of 11KV/415V distribution substation so as to remotely monitor health of the equipment and also locate the fault in 11 KV network • It acquires various DT parameters, such as, oil level, oil & terminal temperature, fire alarm etc. concerned with monitoring of both the transformers and projects it in the form of graphs • It is web based and can be monitored anytime anywhere in the world • It is just to showcase and knowledge our faculty and students on how a smart grid works as the current system would be beneficial only in predicting the faults and Condition Monitoring of the substation, but, in the real world it predicts a fault prior to its occurrence and automatically informs the concerned person via sms
