The continuous development of electric power systems characterized by an increasing potential of decentralized energy generation requires high precision measurement technologies for an effective and reliable network monitoring and system state assessment to ensure the high level of present and future security of energy supply. One possibility to capture system parameters, which has been established primarily within transmission networks, is the use of Phasor Measurement Units (PMU). Taking Smart Grid discussions into account, PMU usage in distribution systems, under particular conditions regarding observability aspects should also be considered [2]. The goal of this paper is to introduce the new requirements for PMU measurement accuracy testing according to IEEE standard C37.118.1 [1]. This publication focuses on two things: the development of automated procedures for a certified PMU test bench, and a way to extend an existing test concept according to the new testing r egulations. Based on these investigations, exemplary and representative measurements, which were made with this automated test bench are presented and analyzed for one proposed static test scenario.
