27P/127P (Phase Undervoltage)
This tab (Figure 14-16) is the Phase Undervoltage with Settable Time Delay. The pull down Pickup menu
allows you to select the relative pickup quantity. The BE1-700 relay measures the voltage input in
secondary voltage. If you want to use primary volts, per unit volts or percent volts, you must coordinate
the settings in CT & VT Setup and Conversions. Whatever the measurement, the method is displayed
besides the settings, e.g., V
PP
(voltage, phase-to-phase). Select the Time delay unit of measure and the
value for the 27P and 127P elements. Select the BESTlogic box at the bottom of the Phase (27P) or
Phase (127P) columns. The status of the logic is shown above the BESTlogic box. A dialog box
(BESTlogic Function Element) opens showing the status of the element logic and the logic scheme name.
If you have a custom logic scheme active, you may change the status of the element logic by pulling
down the menu and selecting from the available choices.
