What is the comparision (advantages / disadvantages) of
110V, 60 Hz system to 230 V, 50 Hz system.

Answer Posted / neeraj pandey

110 Volt, 60 hz system havin the major advantantage of
safety. 110 volt shoch is not dangerous for human.
But the disadvantage is, it requires more conductor as for
same power current is increased.

in 230 Volt system, electrical shock is dangerous for human
but it saves the conductor for same power.

Is This Answer Correct ?    20 Yes 5 No

Dear Sir/Madam, I have one questions we have three steam turbines and one Gas turbine and our industry linked with the public network, we have protection system one of the protection is reverse power we can export just four MW only i would like to ask about how to calculate the reverse power. Thank you in advance best regards

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)
