AC systems installed
on Class 88 Dual Locomotives from Stadler Valencia
This project includes the traction protection function on a standard Saira Electronics AC metering system.
The Protection function (integrated in the energy meter) triggers the VCB control in case of overvoltages, overcur- rents and short circuits. Additionally the leakage current is monitored.
The scope of supply is:
– Standard AC energy meter with integrated 3G communication unit
– AC Transducers with dual output (EMF+Traction)
– Ethernet TCMS interface
– WiFi commissioning
At DCS level the following function has been used:
– Full remote access
– Real time monitoring Advantages:
– Reduced system cost
– Reduced installation time
– Increased system diagnostics
