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,
1 0, 1 5, 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 1 05, 1 1 0,
1 1 5, 1 20, 1 25, 1 30, 1 35, or 1 40% 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.
