IEC 60255-1:2009 specifies common rules and requirements applicable to measuring relays and protection equipment including any combination of devices to form schemes for power system protection such as control, monitoring and process interface equipment in order to obtain uniformity of requirements and tests. This is a misunderstanding: many of the concepts, definitions and test procedures described in the standards are there to be used in relay technique, no matter if the role is relay manufacturer, user, or commissioning / maintenance testing engineer ( [2]. The obtained results through this work show that the designated distance relay with (ANFIS) algorithm has the ability to detect the faults occurrence, recognize it from the cases of the disturbance and to isolate only the fault zone without affecting the work of other relays in system.

This solves the problem of ``nonlocality`` observed in EPR-Bohm-type experiments. IEC 60255-26:2013 is applicable to measuring relays and protection equipment, taking into account combinations of devices to form schemes for power system protection including the control, monitoring, communication and process interface equipment used with those systems. endobj While they allow to reduce the cost of the protection system, they are definitely a challenge for rely test sets, that are required to provide the voltage and current signals to simulate the power system fault, but also the signals need to have the power that is necessary to supply the protection relay.
