Unit 1 Flashcards
Normally the AC volts found within the MEP-12 bare base equipment can be how high?
4160
What happens if electrical current between 100 and 200 milliamperes is absorbed by the body?
Instant death from heart failure
Who MUST perform the isolation of a MEP-12 generator from a PDC?
Qualified electrical systems personnel
Identify the voltage that is considered HIGH voltage. High voltage is any voltage exceeding…?
600 VAC
The MEP-12 generator is rated for which power factor?
.8
What is the MAXIMUM distance MEP-12 can be operated when using a remotely located control panel?
150 feet
MEP-12 generators are positioned so that the prevailing winds blow…?
In the same direction as the radiator fan
What can you do to prevent the brakes from being applied during backing of a MEP-12 generator?
Block the surge brakes
What is the MAXIMUM towing speed you are allowed to tow a MEP-12 diesel generator on paved surfaces?
20 MPH
At a bare base site, how many days of fuel is expected to be maintained at each prime power generation location?
7
How many connections does a fuel bladder have?
3
How many feet tall should the berms be to contain a possible fuel spill at a MEP-12 fuel system layout?
3.5 feet tall
During a pre-operation inspection on a MEP-12 generator the voltage regulator switch should be in which position?
Auto
When starting a MEP-12 which event takes place when the engine toggle switch is released to the run position?
The engine will accelerate to rated speed and the voltage regulator will flash the field
How often should you perform running checks during the time that the MEP-13 generator is online?
At least once an hour
Meter readings are recorded on a MEP-12 generator every…?
Hour
Motorizations occurs when….?
All load has been removed from the generator while it’s connected to the bus
Which meter readings indicate motorization of a generator?
The kW meter at zero or lower, the ammeter is reading amperage, and the PF meter is moving off scale
How are cross currents between parallel generators MINIMIZED if the bus voltage is low and the PF are different?
Raise the voltage to the lead unit
How are crosscurents between parallel generators MINIMIZED if the bus voltage is low and the PF are the same?
Raise the voltage to all units
