2.2.2 Protective Function Specifications
You can individually select each of the protection
functions to initiate an alarm on any, all, or no functions.
A short description of each of the protection functions
follows:
• Voltage phase loss. A Voltage phase loss is
detected when the amplitude of any single phase is
less than 50% of the nominal amplitude.
• Current phase loss. A Current phase loss is
detected when the current amplitude of the smallest
phase is 6.25% of the current amplitude of the
largest phase.
• Phase Unbalance. A phase voltage unbalance is
detected when the difference between the largest
and smallest line-to-line voltages exceeds the
percentage of nominal line voltage by a factor of 5,
10, 15, 20, 25, 30, 35, or 40%. (The Setpoint Switch
position determines the % factor.)Phase Reversal.
A phase reversal is detected if a phase sequence
different from that which was programmed (ABC or
CBA) is detected.
• Overvoltage. An overvoltage is detected when the
amplitude of the AC line voltage exceeds 105, 110,
115, 120, 125, 130, 135, or 140% of the nominal
line voltage. (The Setpoint Switches determine the
% factor.)
• Undervoltage. An undervoltage is detected when
the amplitude of the AC line voltage falls below 95,
90, 85, 80, 75, 70, 65, or 60% of the nominal line
voltage. (The Setpoint Switches determine the %
factor.)
All protected functions update every 1.4 seconds with a
60 Hz line, or every 1.5 seconds with a 50 Hz line.
