Monitoring and Reporting of Voltage Disturbances - Regulatory and Technical challanges and solutions

Voltage quality monitoring has a key role within quality
regulation providing data on the real situation either by
continuous monitoring or by monitoring upon customer
complaints or requests. This paper describes the current
requirements [1] on monitoring of voltage disturbances in
Norway, during continuous monitoring and due to customer
complaints or requests, and the motivation for these.
Further, recommendations from a recent consultancy study
[2] regarding the level of monitoring for achieving reliable
statistics, and on a reporting system for voltage
disturbances, will be presented.
