6.4.2 Systems Equipped With The Seamless Transfer Option
The generator must be started and be prepared to accept the ship’s electrical loads.
Measure the generator voltage using the converter’s metering display, selecting the GENERATOR
POWER
(3)
function. The voltage and frequency must be the same as the converter’s output in
order for the seamless transfer option to successfully transfer power. The SHORE POWER LED
(7A)
must be lit at this time.
When the generator is ready to accept the ship’s loads, press the SHIP’S POWER - GENERATOR
button
(12)
. In dual-generator installations, a display will appear requesting that the appropriate
generator be selected via the F1 and F2
(13)
buttons. In single-generator installations, the transfer
will proceed. The converter will match the generator in frequency, voltage, and phase over a
several second period. When the power forms are matched, the converter will close the generator
circuit breaker, then open the converter output contactor, with both briefly operating in parallel.
The SHIP’S POWER - CONVERTER LED
(9A)
should now be off, and the SHIP’S POWER -
GENERATOR LED
(12A)
should now be lit.
With the ship’s loads now being serviced by the generator, the converter may be shut down. Press
the CONVERTER POWER OFF button
(11)
. The red OFF LED
(11A)
should now be lit. The
converter is now in the standby state.
Next press the SHORE POWER OFF button
(10)
. The red OFF LED
(10A)
should now be lit,
and the converter will begin an orderly shutdown. The complete shutdown process will take
about 10 seconds. The converter power metering display, if observed during the process, will
indicate a slow decay in the output voltage to zero. Rotate the disconnect switch
(14)
to the OFF
position. The system is now off and power can be removed from the equipment.
