Can a 50-Hz designed transformer be used at 60-Hz system? Is the same remains true, when a 60-Hz designed transformer be used at 50-Hz system? Consider only frequency variation. The voltage remains as rated value in all cases. Justify the answer.2 5216
Hello, im taking an introduction to PLC..and i'm having a hard time on creating a program for 2 lamps blinking alternately with this button characteristics: 1.) One push button (starts upon pressing) 2.) Same push button (when pressed again, will pause the system) 3.) Same push button (when pressed again, will continue the paused system) 4.) Same push button (when pressed within 2 seconds, will shut off the system) Pls..i know this is just a simple problem for you guys..2 1841

Practical condition in 400KV Sub station:- Breaker(open) , isolator(open), Earthing (close) at both end e.g A & B. Now Open A Stn Earthing than Open B stn Earthing (Which have a 50MVA reactor) , AND suddenly show R,Y,B phase 704KV,573KV,118KV respectively. Que is without closing of breaker how it is possible.????

at work we have a 3 phase motor but on testing one phase isnt getting a reading. it runs 24 hours a day all week. stops and starts well no noise or heating. the phase isnt down to earth.is it just a bad meter reading or not? phases one and three came up with a resistance reading of 0.4 but phase 2 couldnt get anything shows up as open circuit.
