in fan, inuction motor is used to drive the fan load.
the regulator of fan consists no. of resistance
contact...it changes the the resistance of ciruit.
in starting resistance is kept high for high starting
torque, at that time speed will be low..after this instant
resistances are slowly cut out...and speed will rise..

Hi.. I am a BE GRaduate in E&E. I have 8.5 Experience in Tendering & Estimation field. I have done SAP SD course few years back. But due to some reason i failed to get job in that field and continued my own field. Now I am thinking of changing into SAP seriously. How should i go ahead???
i have a 4 Mva transformer 34.5 kv / 480-277 v and i used 2 parallel 3200 amp bus duct for the secondary feeder using 3 ply of bus bar ( 3/8" x 5" ) as a common where the flexible link terminated and 6300 amps breaker for the main, the lower bus duct reaches 70 degrees and the upper bus duct reaches 55 degrees when i used thermal scanner. why the temperature is not balance when the load reaches 3600 amps.
