Data Acquisition and Processing Method Adequate for High Speed Transient Electrical Events

Many programmable electronic modules for data acquisition and processing can be found in power systems. To monitor and record different specific high speed transient events in energetic systems, an adequate data acquisition and processing method is required. This paper deals with such method and its application in data acquisition for implementation of complex protection functions. The acquisition routine for analog and digital channels, detailed acquisition and storing process for analog and digital values, storing and calculation method for acquired digital and analog values are all presented. The proposed method is adequate for many and various practical applications which require high speed data acquisition systems.
