Abstract
The working principle and the architecture of a calibration system for devices operating with the IEC 61850-9-2 standard are described. Two different types of devices are considered: stand-alone merging units (SAMUs) used to retrofit conventional transformers in power network substations and commercial test sets suited for nonconventional voltage and current sensor calibration in the field. An SAMU is essentially an analog-to-digital converter delivering its results in the IEC 61850-9-2 format. The functionalities of the test set evaluated here are the analog signal generation (voltage and current) and their synchronous IEC 61850-9-2 representation. This paper presents a calibration setup that has been applied to both types of devices.
