If the 469 is applied on a synchronous motor, it is desirable not to trip or alarm on power
factor 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 power
factor trip and alarm elements will be active. Once the power factor is less than either the
Lead or Lag level, for the specified delay, a trip or alarm will occur indicating a Lead or Lag
condition. The power factor alarm can be used to detect loss of excitation and out of step.
The 469 is not designed to estimate power factor when both of the following conditions
are true:
• setpoint System Nominal Frequency is "Variable"
• Input Voltage is not at frequency 60 Hz.
