I have two power supply.a)govt. power b)Captive power.3
phase load connected inside factory.when source change govt.
source to captive some motor rotate reverse. Is phase
sequence changes when if off & on?If I off generator & on it
again is it possible to get changed phase sequence??
how you will decide the distance between the power transformer
and its fencing
in a silicon diode we can measure .7v in a voltmeter.but why
we can't use this voltage for using?
Transformer diagram mention each parts ?
My doubt on cable sizing calculation, Load:74 KW calculated cable 1 run 50mm2. Now client asking us to reduce cable size by increasing runs.
Sir, My question now when my mind strikes with 2 options
1) Divide load 74/2 = 36 and calculate cable for 36+36 making it 2 runs or
2) Simply i can divide 50mm2 /2 ie. 2 runs of 25mm2
Please suggest me sir

I have made a 3 phase thyristor full bridge rectifier. But
at the moment it is working only for the half bridge
operation. Both the half bridges are on operation separately
but when i put it into full bridge operation the
oscilloscope output is zero. I rechecked that the pulses
are correct for each thyristor. what could be the possible
reason for this?
