What 3 factors that affect the output of a generator?
1:The strenght of the main magnetic Field. Determined by the strenght of the field magnets in a permanent magnet machine, or by the number of turns of wire on the field coils and the current through the coils in a wound field machine.2: The number of armature conductors connected in series, which cut the main magnetic field. Determined by the number of turns on armature coils and weather the armature is lap or wave wound, which determines the number of armature conductors connected in series.3: The speed at which the armature conductors cut the main magnetic field. The faster the armature cuts the magnetic Field, the higher will be the value of the voltage generated in the machine
How wartsila abb amg 1600 produce electrical energyand the generator operate?
the prime mover rotates the rotor of the alternator. the exciter contains stator coils with remanence induces voltage in the rotating windings of the exciter rotor which is then rectified and goes through the main field winding. the rotating rotor flux cuts through the stator windings inducing voltage on them. the AVR controls the field current to the exciter stator coils. DC current for pole formation.
What goes on in the tv when you turn it off?
The television has internal electronic circuits which supply established voltage to the essential parts of television, and when switching off, the main supply power from a supply lead through to the television is isolated at the off switch which removes the voltage to the power supply circuits, this voltage supplied by the stabilising circuits the diminishes to practically zero quite soon. With no voltage supplied by these supply circuits the main operating functions cease, but a certain amount of charge is still left within the electronic circuit so this is discharged through the same operating circuits in the form of a small amount of heat. Which is what happens normally anyway. This amount of heat is reflected in the power consumption, and carries on until the voltage supplied is actually zero, and hence no voltage is present to charge the circuits, and now could be classed as safely switched off. The voltage would have been described as having being discharged through the load of the circuits.
What is demagnetising effect of DC generator?
demagnetising effect of dc generator is to reduce main field flux there by reduction in generated voltage.
What is the main difference between an electromagnet and a solenoid?
An elecromagnet is the entire set of coils which produce a magnetic field when an electrical current is run through the wire. A solenoid is a single coil in the electromagnet.
What is separately excited DC motor?
The main difference between the Separately excited motor and the shunt motor is the field cct where as in the second it has its own voltage supply.AnswerI think you mean 'generator', not 'motor'. A 'self-excited' motor is one in which the output supplies the field current, as well as the load current. A 'separately-excited' motor is one in which the field current is provided from an external source.
What are the main systems?
the electricity supplied to a house
What is the main nutrient supplied by fish?
Omega 3
What is a medium voltage ring main?
how, in simple terms, would you describe a ring main (Specifically medium voltage)
How do you clean refrigerator coils to see if it will keep from having it repaired?
It seems like your coils are the main problem. I would suggest looking at professionals who best work with refrigerators, they can fix your coils and it will not damage your fridge.
Isolating transformer theory?
Transformers use magnetic induction between 2 coils of wire to produce a voltage in the secondary winding. Typically the main purpose of a transformer is to step up or down the voltage by having differing number of windings between the primary and secondary coils. A secondary effect is to keep the 2 systems electrically isolated from eachother. If one of the phases becomes grounded, the ground is only seen on the portion of the system downstream of the transformer, thus increasing relibability.
How are current and voltage related to the power supplied by the source?
in ac circuits power,P=VICOS@ @ is the angle between voltage and current. in dc P=VI V is the voltage I is the current. Power (in Watts) is current (A) x voltage (V)
