System Requirements of Real Time Continuous Data Acquisition for Power Quality Monitoring

Data acquisition systems for power quality monitoring have complex requirements which also vary with the intended application. Overall, the complexity of an instrumentation system for power system monitoring is most dependent on the number of channels and sites which must be analysed, and the required time stamping accuracy. Three broad categories of system configurations are described with their basic parameters. The emphasis is on a discussion of hardware and software issues which are involved in a system specification.
