turned off. Use a grounding rod before working on the circuit to discharge high voltage capacitors.

What is residual voltage for DC generator?
This case arises only in series dc generator current should be sent around the poles to magnetize. this current can the source(generator). current is passed through poles if it is loaded. but if it is not loaded current is zero through the field. load voltage should be zero actually.but this dont happen.we use generator frequently.due to this poles are partially magnetized this causes some voltage appear called residual voltageAnswerThere's no such thing as 'residual voltage'; you're confusing it with 'residual magnetism', which exists in the magnetic poles of a self-excited d.c. generator and which enables the build-up of its terminal voltage.
If a selfexcited generator has lost all of its residual magnetism can it build up an output voltage?
yes
What is the definition of applied voltage?
Any voltage that is fed into or "applied" to an electrical circuit is referred to as an "applied voltage".

What is the definition of grounding as in electricity?
It is where a point in a circuit is at zero voltage.
What is meant by residual voltage in a dc generator?
poles are partially magnetized this causes some voltage called residual voltage
What is the definition of residual hills?
Residual hills are landforms that remain after erosion has worn away surrounding material, leaving isolated hills or ridges behind. These hills often have a more resistant rock composition that withstands erosion better than the surrounding material. Residual hills can be found in various landscapes around the world.
What is the residual voltage of a 380Vac 264KW generator?
Residual voltage is the vector sum of all three phase voltages. Ideally this will be zero.
What is the definition of Residual Engineering?
Residual engineering I think is the thought and kinetic process of recycling energy.
What is residual voltage in lvdt?
Output voltage at the null position is ideally zero. But because of harmonics in the excitation voltage and stray capacitance coupling between primary and secondary usually some nonzero voltage exists at null voltage. This is called residual voltage. If it is less than 1 % of full scale output voltage ( which is the normal case) it is in the acceptable limits.
What is the definition of residual disability?
Basically it is a continuation of your prior disability claim.
How initially voltage build up in an alternator by residual magnetism?
The residual flux will help the phenomenon of changing flux. So that emf generation takes place.

yes
What is definition of feedback factor?
The ratio of Feedback voltage and output voltage.
How the doubly fed induction generator build up voltage?
If a self-excited generator lost all its residual magnetism, can it build up an output voltage?
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism
