Generation stations/ power plant
Where the electrical power is generated these stations rotate a magnetic field that produces electrical energy for AC current.
Nuclear fission
Control rods are fed into a reactor core to achieve
Voltage desecrated to zero
Rotated to 180 degrees
Maximum/ peak positive
Generator has rotated 90 degrees
Peak negative valves
270 of rotation
Frequency
Number of times that a generator rotates
Nuclear fired generation
20% of electrical energy produced in the us today
The opposite charges attract
Law of charges states
Combined cycles
Hot exhaust from natural gas turbine is used to produce steam
Wind generation
Fastest growing method of producing electricity
360 degrees of rotation
When voltage has returned to zero
Cycle is referred to?
One rotation
What 3 loads make up “ac”
Resistive
Inductive
Capacitive
Energy in motion is most often seen where?
Electrical motors
13,800/24000 volts
Generation stations
High pressure steam is produced by 4 things
Fossil- fired generation
Nuclear-fired generation
Geothermal generation
Solar
Crude oil
Heating of oil in a boiler which boils into steam
What does law of physics state
Energy can be converted but not created or destroyed
Terms “+” and “-“ refer to
Direction of current flow
Natural gas
Fossil fuel formed from decaying matter of buried plants, animals and other gases
Geothermal
Natural heat from geysers or hot spring to produce steam
RMS
Foot mean squared
Resistive
Direct current has one type of load
Rms
Ac valve of volts that produces the same power as D.C.
