Overview
The “Current jump detection” function detects jumps in the phase or zero-sequence current (ΔI), and generates an indication when the measurands change by more than a configured threshold value from one system period to the next.
For more detailed information on “Current jump detection” function, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
