CHAPTER 5: SETTINGS
5.11.3 Reactive Power
PATH: SETTINGS ZV S10 POWER ELEMENTS ZV REACTIVE POWER
If the 469 is applied on a synchronous motor, it is desirable not to trip or alarm on kvar until
the field has been applied. Therefore, this feature can be blocked until the motor comes up
to speed and the field is applied. From that point forward, the kvar trip and alarm elements
will be active. Once the kvar level exceeds either the positive or negative level, for the
specified delay, a trip or alarm will occur indicating a positive or negative kvar condition.
The reactive power alarm can be used to detect loss of excitation and out of step.
