Figure 16-1. Overshoot and Undershoot Chart Recording
Divide each of the values obtained
in (a) by the rated voltage of the
generator and multiply by 100 to
convert to percentage.
To determine the maximum overshoot
and undershoot at each load step, and
express this as a percentage of its rated
proceed as follows:
From the meter recording charts,
determine the maximum amount
that the voltage trace goes beyond
the line (3) of the observed voltage
band following the load change.
