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