- 1if the main Ac producing generators in an ac fail, what other component of the electrical system will produce/supply Ac power? the static inverter.the static inverter.
- 2what is the static inverter?It converts 28V DC from the battery to 115V 400hz by the use of transistor.
- 3benefits of batteries connected in parallel?increae the total amp hour capacity
- 4TRU? transformer/rectifier unitconvert AC to DC at a lower voltage
reckkt = ac dc
reckt = bad / lower - 5full wave bridge rectifiers?...
- 6batteries connected in a series?positive to negative......
increases total voltage at a constant amperage. - 7batteries in parallel?increases total amperage at a constant voltage
- 8is series or parallel more common?parallel
- 9how is a batteries capacity measured?amper hours.
- 10Ni-cad batteries don't like?shallow cycling.
instead they need deep cycling. - 11Lead acid don't like....deep cycling...
instead they need shallow cycling. - 12IN a eries wound generator, as load increases, output?also increases.
- 13What happens when a gen breaker trips?the associated generator is disconnected from its bus.
- 14constant frequency alternators are good for PARALELLING..
- 15WHERE ARE DIODES FOUND?RECTIFIER
- 16WHEN WILL A GENERATOR BREAKER TRIP?WHEN THE GENERATOR DEVELOPD A FAULT.
doesn't matter if if the generator is out of timing with the others. - 17When is a CSD required? constant speed drive.(like a CSU). its when the engine drien generator has varying RPM.
