Transmission Operators have always faced challenges

• Criticality of safety and reliability
• Generation/consumption imbalances
• Grid instability and failure

The modern Transmission Operator has additional challenges

• Increasing amounts of renewable generation
• Reduction in system inertia
• More volatile and complex generation and flow mix
• Higher harmonics and deterioration in power quality
• Increased interconnections

As a result real-time visibility of the transmission network is more critical than ever.

sub.net is a multi-function substation monitor capable of capturing everything from high speed transients to longer term system stability events which are analysed and reported on immediately.

sub.net also operates as a Phasor Measurement Unit (PMU) in Wide Area Monitoring Systems (WAMS).
