What is the input of a generator?
Generators transform energy into electrical energy. The output of the generator is the electric power it "makes". The input is whatever is used to create mechanical energy to turn the "prime mover", or the thing that makes the generator spin (be it steam / thermal energy, water, wind, etc.).
Why a dc shunt generator may fail to self excite?
If there is no residual magnetism in the field poles then there would be no flux too induce the initial voltage for self exitation
Why is reverse power protection required in units like signal generators?
Results of Motorization of a GeneratorIf a generator loses prime mover power, it acts as a motor with a DC field on the rotorThe DC field will cause the rotor to try and follow the AC field in the same direction as beforeIf the mechanical drag on the rotor is heavy, it will fall behind and "slip poles,"inducing a large voltage into the rotor; this can cause insulation breakdown of the windings, flashover at the brushes, and violent shaking of the generator mountings.If a generator loses DC excitation to the rotor it will not generate, but the prime mover power will still turn the rotorNow the generator acts as a motor running at no load
Why the synchronous machine rotate at synchronous speed?
The spatial distribution of the windings in the armature is designed in a way such that it produce a rotating field when a three phase source is applied to its terminals. The field windings have a DC field applied to it and it is rotated mechanically by a prime mover. If the prime mover tried to rotate the synchronous machine at speed higher than its synchronous value then the power output of the generator will increase and this causes the speed to "lock" again to the synchronous one. If the prime mover applied less torque then the machine will slow down but the power output will decrease DUE TO DECEASE in the applied torque and this cause the machine to "lock" again to synchronous speed of the grid. The same principle can be applied to synchronous motors except that torque is negative (i.e. the prime mover is applying negative torque)
Which statement describes an AC generator?
AC generator is a rotating machine with a rotor and stator winding, driven by another prime mover, which generates alternating current at a specified voltage.
What happen to alternator when prime mover fails?
alternator does not rotate
How do generators run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
What does the company Veo produce?
Veo produces: turbine generators, the VEDA 500 low-voltage switchgears, marine generators, thrusters and prime mover motors and transformer stations.
How generator run?
By help of prime mover which supplies the mechanical energy to the shaft of generator(in case of dc generators).
What are SIC 3621 product lines?
In 2001 the industry's products consisted of four primary product groups: fractional horsepower motors, integral horsepower motors and generators, land prime mover generator sets, and parts and supplies for motors and generators.
What factors affect the rotation in a DC generators?
Your question is unclear. Do you mean how the rotor of a d.c. generator is driven? If so, then its shaft is connected to a 'prime mover' which can be an internal combustion engine (petrol or diesel engine) or a turbine (steam, water, gas). The type of prime mover usually depends on the source of fuel available to operate that prime mover and whether it is fixed or portable.
What city did the reign of terror happen?
It was not limited to Paris, but Paris was certainly the prime mover.
What will happen to your existing curve if the speed of the rpm mover is increased Give reason for your answer?
