The differential protections present basic protection to protect power transformers, motors, generators, blocks power transformer-generator, bus bars and important lines. Differential protection has to operate in very short time to faults in the protection zone, but it must not operate to faults outside. Control and protection unit REF 542plus is used to protect in medium voltage systems. Unit REF 542plus has a lot of protection functions even the differential protection function. This paper deals with measuring of accuracy of the differential protection function algorithm in the unit REF 542plus applied to protect power transformer because in this case are the highest requirements (vector group adaptation, difference between nominal primary current and nominal secondary current, etc.) It was measured the minimum setting values of the characteristic of the differential protection. Differential current was generated by the amplitude simulation of incoming and outgoing current. At the end is evaluated accuracy of the algorithm.
