Basic Air and Elec Flashcards
What are Volts
The unit of measurement for electrical potential
What is DC
Direct Current
What is AC
Alternating Current
what type of braking does not use friction
Rheostatic/electrodynamic braking
how does Rheostatic/electrodynamic braking work?
It uses a magnetic field within the traction motor to provide resistance
What is a Transformer?
Takes AC voltage in and changes it higher or lower but still AC.
What is a Alternator?
Converts DC power to AC
What is a Rectifier?
Converts AC to DC
What is a Inverter?
COnverts DC to AC
What is a Air Cooler?
Cools down the air
What is a Air Dryer
Air dryers remove water, oil, and solid particles.
What does a compressor governor do
Monitor the air pressure within the main reservoir/maintain a consistent level of pressure
