I am responsible for a. Reduction in total operational cost of Airtel sites of Pune cluster. (There are more than 1000 sites in and around pune District).b. I am an in charge of 4 Electrical Engineer and more than 50 technicians. c. I am responsible for the uninterrupted electric supply for the continuous operation of sites.d. I have the complete Knowledge of GSM.e. I also know about RF. PROJECTS/ SEMINARS (Final Year Project of Engineering)Reliability analysis of 132kv Transmission substation, Chikalthana, Aurangabad For Reliability Analysis we have used different reliability indices e.g. SAIFI (System average interruption frequency indices), SAIDI (System average interruption duration indices) CAIFI & CAIDI. To calculate these indices first we found out total time of interruption (in hours) for a particular year by using MSEB’s Distribution interruption schedule. After this we found loss of revenue (in Kw and Rupees also). After studying interruption data collected from MSEB there are three major causes for the power interruption 1. C.T. & P.T. failure due to over loading. (Up to 40% of total interruption) 2. Jumper Cuts Failure. (Up to 30% of total interruption) 3. Insulation Disc failures. (Up to 15% of total interruption) We observe that maximum faults (in hours) are in the months of July & August. We also found Optimum feeder /conductor design by using MINITAB software provided by Crompton Greaves. Conclusions:1. Proper metering should be present at different tapping place.2. Regular data of interruption should be properly maintained.3. All the connections of cable and overhead line should be properly riveted and bolted to avoid jumper cuts failure.4. Power factor should be properly maintained to unity.5. Restraining for harmonics should be properly provided.
