Norway: Norwegian Transmission System Operator (TSO) Statnett has adopted Synaptec’s distributed sensor technology to improve busbar protection.
Both mechanical and electrical monitoring functions are combined in a single, completely passive IEC 61850-compliant system.
A version of Synaptec’s Refase system will be installed in a major substation in Oslo, Norway, initially as a shadow system; this will allow comparisons of performance against traditional instrumentation technologies through Norway’s extreme seasonal temperature changes and ultimately quantify how much planned outage time, space (and therefore cost) can be saved. With one system able to instrument 50 locations synchronously, six busbar feeders will be independently and simultaneously protected by one system, with the capacity to spare for novel temperature and vibration monitoring of nearby high-voltage (HV) assets, such as transformers.
Synaptec and Statnett expect to reduce planned outage times, lower the capital cost of busbar protection schemes, but also to improve operations and maintenance processes by adding remote mechanical monitoring of critical HV assets through one IEC 61850 stream.
