THERMAL
 Boilers  Steam Traps  Steam Distribution  Insulation

Electrical System Network & Transformers
• This would include detailed study of all the Transformer operations of various Ratings / Capacities, their Operational Pattern, Loading, No Load Losses, Power Factor Measurement on the Main Power Distribution Boards and scope for improvement if any. The study would also cover possible improvements in energy metering systems for better control and monitoring.
5

Motive Load
• Study of above 10 HP motors in terms of measurement of Voltage (V), Current (I), Power (kW) and P.F. in a complete cycle, and thereby suggesting measures for energy saving like reduction in size of motors or installation of energy saving device in the existing motors. • Study of Mechanical Power Transmission Systems (Pumps / Fans/ Blower etc.) to evolve suitable recommendations wherever feasible for Energy Efficiency Improvements.
6

Illumination System
• Study of the illumination system, LUX level in various areas, area lighting etc. and suggest measures for improvements and energy conservation opportunity wherever feasible.

7

Compressed Air System
• The audit would involve analysis of various parameters like Free Air Delivery (FAD) Capacity
