This was a nice surprise for me. Older versions of the SR-745 have a maximum voltage of 200kV. If you use newer software to set the relay, it indicates a maximum voltage of 2000.0 kV. If a voltage setting higher than the maximum is uploaded, the relay automatically divides all voltage and MVA values by a factor of 10. There is NO warning when this happens. This fix does work but will be a shock when someone else looks at the settings afterward. A good fix is to change the voltages to line to ground values.
