3. Main Function
●
Transformer protection(enable with current transformer) and auto
reclosing
● RS***5
communication interface was designed to make the system capable of
net communication
● Manual
adjustment of residual operating current value, or self-regulate
the residual operating current value as the line
leakage
●
Query-able for all previous tripping time, fault current
● Account
the data of maximum load current per month, the data will be
stored safely for *2 months(enable with current
transformer)
● Adjust
the overload protection value as the capacity of distribution
transformer or the actual load (enable with current
transformer)
● Account
the times of trip(previous, current month and total)
● Digital
display the value of three-phase currents(enable with current
transformer), voltage(Optional), leakage current
● Be able
to identify and separate surge leakage current(Optional)
