The FAME plug-in test system allows the setup of test sockets that are individually adapted to match different tests scenarios -- such as IDMT protection or distance protection. A range of accessories including color-coded 1-pos.
The solution features patent pending short distance protection, which adjusts the transmit power when the receiver is placed closer to the transmitter.
There is always need to mature directional relaying because it is cost effective and technically sound solution of the very phenomenon as local back up of distance protection. Fuzzy logic can solve these complex problems more efficiently by taking an optimized decision relative to severity of a disturbance.

Current protection projects are investigated from two perspectives; on the one hand, to improve the protection of traditional distribution network to reduce debugging time, increase sensitivity and improve the quality of the feeder, and on the other hand, for the protection of transmission lines that are evolutionary theories and are used in power distribution networks, including distance protection and pilot protection [13].

In Sections 2 and 3, a brief introduction of power system faults and artificial neural networks is provided, Section 4 is about distance protection by ANN method; in Section 5, ANN and its application for protecting transmission line are illustrated.
An adaptive distance protection of double-circuit line using zero sequence thevenin equivalent impedance and compensation factor for mutual coupling to increase the reach and selectivity of relay has been developed in [2].
Therefore, to fast clear the close-in fault, we still need to resort to distance protection which is operated based on single-end electric quantity.
In this paper the relations betweens different types of power oscillations and distance protection is examined.
The objective of staged-fault testing in the Croatian power system was to evaluate a distance protection settings, the performance of distance teleprotection scheme and verify coverage on a three-terminal line due to infeed/outfeed effects.
