Overview
The “Fault locator plus” function is used for 2-sided measurement of the distance to the fault location. It also reliably detects the fault location in case of 2-sided infeed, ground faults, and in case of fault resistances and can be used for fault-location determination in case of non-homogeneous lines. The Fault locator plus function calculates the fault location with the measured values of both line ends.
For more detailed information on “Fault locator plus” function, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
