of the generator (or exciter) field either remain unchanged or have only minor variations about an equilibrium condition
with no evident continued increase or decrease in value after the last adjustment to the load, voltage, or frequency has
been made.
(b)
No further adjustments shall be made to any set control for the remainder of this test except the
control panel voltage adjust device.
(c)
Record all instrument readings.
(d)
Remove load.
(e)
Record all instrument readings (after transients have subsided).
(f)
Adjust the terminal voltage to the maximum specified value.
(g)
Record all instrument readings.
NOTE
All voltages above rated values, the generator will be supplying less than rated current; and at
voltages below rated values, the generator will be supplying greater than rated current.
Caution should be taken to avoid damage to instrumentation and load banks.
(h)
Apply rated load (rated kw at rated power factor).
(i)
Record all instrument readings (after transients have subsided).
(j)
Remove load and adjust voltage to the maximum attainable value or to a value just prior to actuation
of the overvoltage protection device.
NOTE
The output voltage may exceed the rating of-connected equipment.
(k) Record all instrument readings (after transients have subsided).
(l) Apply rated load.
(m) Record all instrument readings (after transients have subsided).
(n) Adjust voltage to the minimum specified value at rated load.
(o) Record all instrument readings (after transients have subsided).
(p) Remove load.
(q) Record all instrument readings (after transients have subsided).
(r) Adjust voltage to the minimum attainable value or a value just prior to activation of the undervoltage
protection device.
(s) Record all instrument readings (after transients have subsided).
(t) Repeat steps (a) through (s) above for all other voltage connection(s).
d.
Sample Calculations. Regulation (droop) is defined for the purpose of this method as the no-load value minus
the rated load value divided by the rated load value the quantity expressed in percent.
