The SCADA integration project allows TasNetworks to monitor and historically trend the presence of fault gases present in the oil of transformer main tank.
We thank our client for trusting us with these key assets, with supply from this equipment feeding the Hobart CBD, Hospital, nearby schools, businesses and residence.
– Carbon Monoxide
– Total Dissolved Combustible Gases (TDCG)
The gas quantities were collected into the Substation Gateway RTU from the Kelman Multitrans DGA using Modbus protocol over serial fibre optic communication. From the Substation Gateway RTU protocol conversion to DNP3 was implemented mapping the analog values to the Control Centre SCADA system (Master Station).
Oil temperature monitoring and fan control is supplied by a Dynamic Ratings DRMCC a PLC based transformer monitoring system.
- Dissolved gas analysis (DGA) is the study of dissolved gases in insulating oil, with the concentration and rate of change used to identify developing electrical faults.
