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.
