Desktop VR Applications for Statnett SF

During the autumn of 1998, two applications were implemented to evaluate the viability of using PC-based desktop VR technology for planning substation operations and maintenance activities at Statnett.

GIS System. A model of a 420kV GIS (SF6 Gas Insulated System) system has been created. The user can look inside switches, visualise gas chambers and current, and control parts of the system using a control panel. Components can be clicked on to retrieve information from a Microsoft Access database. The model is primarily a visualisation tool for maintenance planning.
Cell Model. The second application is a training system for teaching safety procedures for disconnecting, and reconnecting, a cell in a 47kV system. The trainee can use the model in an explorative mode, to see how the system responds to various actions, or as a procedural training system where the trainee is guided through the steps of procedures and receives feedback when incorrect actions are attempted. The trainee can visualise where current is flowing at any time and can also choose to look at components from physically impossible positions to see how they work.

Both applications were implemented in VRML 97, JavaScript and Java.
