generator is an electronic machine that uses diesel as fuel to run the engine which rotate the motor of an alternator which produce
the electricity. As we all know that we cant destroy the energy only wee can convert it to one form to another .

So generator is also a type of machine which convert the mechanical energy into electrical energy.

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.
