Why two nos. un-tensioned wires are placed inside the PSC poles used by powergrid in RGGVY works.
2 6830i work as a technician at a private company.. i used to take amp reading for certain appliances such as air con.. the problem is when i clamp the neutral, wire there is a current reading.. from my understanding for single phase system neutral should not have current unless if the circuit is not complete.. yet the air con still work
3 5770what will be the effect on a bulb in case its connetion is change from live and neutral to live and ground??? 1) in case of single phase AC supply 2) in case of DC supply.......???
1 4174what will happen when excitation of a synchronous machine is suddenly reduce to zero when it is running at full load..??

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
we have consol make 3 phase servo stabilizer for cnc m/c. while installing the earth neutral voltage is 1.7 volts at stbilizer off condition and when stabilizer get on en voltage reaches 4.8 volts (new earthing is done and neutral is helthy condition all phase to neutral volts 440,442,441 v)why this happen.solution for cause.
