sub.net is a web enabled multi-functional power monitoring system incorporating wide ranging recording, analysis and reporting functionality for use in the electricity supply industry and industrial plants. This makes sub.net ideal for use with Smart Grid where the internet is used to deliver useful information on the state of the network to people and processes.

sub.net continuously monitors and reports on protection operations, quality of supply, stability and substation asset conditions. Real time monitoring and metering are other integral features.

sub.net is a very flexible system which covers a wide range of monitoring applications and meets the evolving needs and demands of the power supply industry. It will significantly reduce engineering fault analysis time, assist in network improvements and aid fault location to reduce customer interruptions and minutes lost (CI/CML). Installation costs are greatly reduced due to the very compact enclosure.

sub.net provides automatic analysis of the data from system events and sends prioritised reports via email. This enables rapid engineering assessments to be made and appropriate prompt actions to be taken. There is now no longer any need for large volumes of data to be retrieved from multiple instruments to a centralised master station before information can be made available to users.

Remote communications are via LAN, PSTN, GPRS & 3G connections. As event reporting is by email any number of sub.nets can process and transmit reports at the same time delivering timely information directly to users’ desktops and smart phones. The source data may be included as attachments in Comtrade or CSV format. Because sub.net works in this way a master station application is not required saving time and money.

A web browser is all that is required to see all the reports, the present input and computed values and the system configuration. The DIN rail mounting design enables internal panel fixing of the sub.net close to the input connections. This, together with its very compact size, enables big reductions in both panel space requirements and wiring costs.

sub.net power network monitor delivers visibility of today’s ageing electrical network, and tomorrow’s smart grid, to maximise efficiency and reduce risk. Sub.net introduces automatic analysis to the substation, monitoring and identifying problems throughout grid installations – reducing costs and saving time and money.
