10.1.12 OVEREXCITATION
This protection should be set to coordinate with the manufacturers excitation capability curves. For example system, the
combined generator/GSU limit curve is shown below:
Figure 10–4: GENERATOR/GSU LIMIT CURVE
Program the volts per hertz 1 element with an inverse characteristic (curve A), a pickup of 1.05, and a TDM of 40. Program
the volts per hertz 2 element with a definite time characteristic, a pickup of 1.23, and a time delay of 2 seconds. Both ele-
ments will issue a trip. The volts per hertz 1 pickup will be used to generate an alarm. Either source may be assigned in this
example. Make the following changes in EnerVista UR Setup or through the
