Table 2-13: Over Voltage Settings
Item Option
Over voltage
pickup Adjustable from 110% to 150% in
increments of 1%.
Over voltage
delay Adjustable from 1 sec to 15 sec in
increments of 1 sec. Setting this value
to OFF disables this function.
Power Reversal Relay
This function measures the direction of power flow through
the breaker and initiates a trip if a sufficient magnitude of
reverse power is detected.
Table 2-14: Power Reversal Settings
Item Option
Power reversal
pickup Adjustable from 10 kW to 990 kW in
increments of 10 kW.
Power reversal
delay Adjustable from 1 sec to 15 sec in
increments of 1 sec. Setting this value
to zero (0) will disable this function.
Power Direction Setup
This function selects the normal power flow direction for
the breaker. Set this parameter to match the direction of
current flow through the breaker during normal operating
conditions. This direction setup also affects the sign of the
normal power metering displays.
Potential Transformer Voltage
Enter the primary voltage rating of the potential
transformer. The range of values is 120 V to 600 V, with an
increment of 1V. The voltage input coming into the trip unit
must be wired into using voltage conditioners which steps
the voltage down to an acceptable voltage level. See below
for voltage conditioner plate wiring diagrams.
