Application The operation of transmission networks today is in many cases close to the stability limit. Due to environmental considerations the rate of expansion and reinforcement of the power system is reduced for example, difficulties to get permission to build new power lines.

The ability to accurately and reliably classifying different types of fault so that single pole tripping and autoreclosing can be used which plays an important roll in this matter. Faulty phase identification with load encroachment for mho (FMPSPDIS) function is designed to accurately select the proper fault loop in the Distance protection function dependent on the fault type. The heavy load transfer that is common in many transmission networks may in some cases be in opposite to the wanted fault resistance coverage.

Therefore, FMPSPDIS has an built-in algorithm for load encroachment, which gives the possibility to enlarge the resistive setting of both the Phase selection with load encroachment and the measuring zones without interfering with the load.

The load encroachment algorithm and the blinder functions are always activated in the phase selector. The influence from these functions on the zone measurement characteristic has to be activated by switching the setting parameter LoadEnchMode for the respective measuring zone(s) to On.
