how to calculate the slowness and fastness of energy meter if we have different kw load for example (0.746 kw and meter rev constant 400 and we calculate the 2 rev in 30 sec) please explain the formula thanks
Answer Posted / k.prakashchandra
Meter rev constant means rev/ kwh ? Then one rotation =60x60/400 or 9kws . 2 rotations = 18kws.Time taken is 30s. Then the av load is 18/ 30 or 0.6 kw

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.
