Engineering AllOther (1379) 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)
1897If a generator of generating station produces 100MW rated output then what will be the rating of the step-up transformer connected to it?
5 6769Q : How to calculate cooling water pumps head, do I need to consider static head and frictional loss of the pipe with high elevation? I mean to say is discharge pipe branches to several elevations and joins to the cooling water return line. The highest elevation pipe goes to a heat exchanger at (xx) psi inlet pressure. Should I consider only pump discharge header and this piping for head calculations? How about frictional losses in return pipe? Pressure recovered in return piping is good enough to make it back to the cooling tower?
1 10600as we see that in our country the power rating for transmission is always rated in multiple of 11 like 11kv,33kv,66kv132kv. So i want to know wht is reason or logic here.

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
