82
Soft logic utility to perform mathematical and logical operations
IEC61131-3 compliant PLC type logic with full support for 5
programming languages
Maintain steady voltage based on user-defined targets and
settings
A master local/remote switch to control the local/remote state of
distributed devices
Enables the use of individual relays (with external terminations) as
master trip/close relays
Adjust setpoints based on control request durations or analog
input values
Translate status points into scaled analog input values to reflect
transformer tap positions
Automatically reclose tripped circuit breakers following momentary
faults
Patented load transfer scheme isolates faults and restores power
to non-faulted sections if possible
Improve reactive support during peak periods through more
effective use of existing capacitor banks
Locate and isolate faults to reduce customer outage times
Monitor a network of substations and move load off overloaded
transformers to other stations as required
Shed load intelligently during overload conditions
