Check the settings for “Angle” and “PN” using an accurate test
set according to the following procedure:
a) Inject purely active power at rated voltage and current.
b) The active power measurement must be as close as possible
to 1.000 or oscillate symmetrically to either side of it.
à Adjust the value of “PN” as necessary.
c) The reactive power measurement must be as close as
possible to 0.000 or oscillate symmetrically to either side of it.
à Adjust the value of “Angle” as necessary.
