Is it true online ups having bypass mode if it is true then why we called ups because it is interrupting power when goes in bypass mode
20301. If 8.35%Z means the percentage impedance of 132kV-line from power company, we will like to confirm its base capacity?
19782. If 8.35%Z means the percentage impedance of 132/11kV transformer self,will like to reconfirm the percentage impedance that is supplied from power company?
2 6304y we use neutral,all r told its used to for closed path..k its a just used to closed path,in a transmission line y we put same conductor used n both phase and neutral..if we use less than phase conductor in neutral mean we ll reduce cost its right r wrong..if we use mean any problem occur in transmission line..
ME,

Dear all, i completed M.E(Power Electronics & Drives) 2011 passed out having 78% so i need job in core side but i don't know how can i receive the calls from electrical companies and i uploaded my CV in naukri, times jobs etc.. In that iam not recieved any mails from good companies so give me best procedure plzzzzzzzzzzzzzzzzzzzzzzzz..... Thanks, K.Linga Reddy Email-id:-lingareddykmthm@gmail.com Ph no:-08015402078
how to calculate cooling requirement of datacentre from electrical load?
If any HVDC line is going with positive & negative(the negative usually have return path of current with earthing electrode). Now the question is if this HVDC earthed electrode which is using as return path and earthed any nearby 400kv or 220kv AC substation equipments. which will be the impact of this on AC substation & its equipment, how severe may be this and what should be the minimum distance require between HVDC earthed electrode and AC substation equipments? It's really an high engineering level question...Dare to answer and increase your knowledge.
