production line runs 24 hours for 6 days. transformer size is 1000kVa. what would be the life span of that unit and what sort of preventative maintenance programmes must be implemented?

 

Jim...

1) Is daily load heavy-industrial, or light-maufacturing?

2) What is load in kW, and Power Factor!

3) Is xfmr the dry-type or oil-immersed?

4) What are primary and secondary voltages?

5) Is xfmr outdoors or indoors?

6) What is average ambient-temperature?

7) On the 7th day is load removed, or is transformer shutdown?
