 English term or phrase: field flashing We are dealing with gas turbines. The paragraph is about initiating field flashing to build up generator voltage to power certain devices. I found the explanation in English: Generator field flashing is required when generator voltage does not build up and the generating system does not have field flash capability. How do I say it in Italian? Thanks a lot

FIELD FLASHING
When the regulator is operated with the generator
for the first time, the polarity of residual
magnetism may not be correct or the magnitude
may not be enough. If the generator does
not build up, shut down the prime mover and
proceed as follows.
a. With the prime mover at rest, apply a dc
source (not grounded) of not more than
48 Vdc to terminals F+ and F– in series
with a limiting resistor. Use 1 ohm of resistance
for each volt from the dc source
with a power rating of at least 1 watt per
volt.
b. Allow approximately 30 seconds before
removing the dc source.
c. Start the prime mover and measure the
voltage at the regulator leads 3 and 4. If
the voltage is greater than 6 Vac, voltage
buildup should occur. Repeat flashing if
