Power quality issues are an increasing concern for our customers and all distribution network operators. Computer technology, automated processes and sensitive electronic equipment are in widespread use across all customer sectors.

Short duration interruptions and voltage sags are the most frequent cause of loss of revenue to commercial and industrial customers as they can result in mal operation of equipment. Installation of low loss distribution equipment and network configurations designed for optimizing the connection of low carbon devices may allow power quality issues to propagate further with single events disrupting more customers.

Monitoring an extensive sub transmission network, which is suspected to contain sources of power quality issues will provide the opportunity to identify the extent of the propagation of power quality issues and allow alternative mitigation measures to be considered and possibly demonstrated to evaluate their effectiveness.

Confirm the extent of suspected power quality issues on an extensive sub transmission network and consider the effect of alternative mitigation measures.
