What else can I help you with?
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 residual voltage in photocopiers?
Residual voltage in photocopiers refers to the small amount of electrical charge that remains on the photoconductive drum or belt after the copying process is completed. This residual charge can affect the quality of subsequent copies by causing unwanted marks or streaks. It's important for photocopiers to effectively neutralize or manage this residual voltage to ensure optimal performance and image quality. Proper maintenance and cleaning can help mitigate issues related to residual voltage.
What is residual voltage of lvdt?
Residual voltage in a Linear Variable Differential Transformer (LVDT) refers to the small voltage that remains at the output when the primary coil is energized, but there is no displacement of the core. This voltage can arise from imperfections in the LVDT's construction or external factors and may affect the accuracy of measurements. Ideally, the residual voltage should be minimized or compensated for to ensure precise readings.
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.
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?
What is meant by residual voltage in a dc generator?
poles are partially magnetized this causes some voltage called residual voltage

What is definition of residual voltage?
Net voltage in the Neutral of a three phase electrical system is called residual voltage.
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.
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.
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
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?
How residual magnetism present inside the self excited generator?
Residual magnetism in a self-excited generator refers to the small amount of magnetism that remains in the magnetic core after the generator has been de-energized. This residual magnetism is crucial for the initial excitation of the generator because it provides the necessary magnetic field to induce voltage when the generator is started. As the rotor turns, the residual magnetism induces a small voltage in the stator windings, which, when connected to the field windings, enhances the magnetic field and leads to self-excitation, allowing the generator to generate power. Without sufficient residual magnetism, the generator may fail to start or produce voltage.
For a 3 phase alternator why there is an AC voltage generated in the absence DC excitation?
due to residual magnetism
