AC Generators Flashcards
1
Q
what x3 things are required to produce a EMF
A
- ELECTRIC CONDUCTOR
- MAGNETIC FIELD
- REALTIVE MOVEMENT
2
Q
What’s the most common generator in use today?
A
BRUSHLESS
3
Q
what x2 things that the generated EMF output will depend on
A
- THE AMOUNT OF LINES OF FLUX CUTTING ACROSS THE CONDUCTOR (VOLTAGE)
- THE SPEED THAT THE LINES OF FLUX PASS THE CONDUCTOR (FREQUENCY)
4
Q
What x2 things are connected to the AC generator to make it turn ?
A
- PRIME MOVER
2. DIESEL GENERATOR / GAS TURBINE
5
Q
How is the HF generator turned? what is its output and where is it fed to ?
A
ITS BELT DRIVEN
ITS OUTPUT IS 115VOLTS - 1-PHASE - 1600HZ
AND ITS FED TO THE AUTOMATIC VOLTAGE REGULATOR
