I know current,volt,powerfactor of an electrical line. In
this line how I will calculate Active power and Reactive power

Answer Posted / v.r. shinde

For active power.

P= V*i*cosQ ( watts) wherw Q is the angle between phase
vol. & phase current.

For Reactive power.

P = V*I. ( VA)

Is This Answer Correct ?    2 Yes 1 No

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.

I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)
