One power meter on the outgoing line control panel gives less than half of the correct power output. This is the same with the power meter on one of the unit control panels.
The set up is a mini hydro with two units rated at 500kW generating at 400V which is stepped up to 33kV. Then one outgoing 33kV line comes out from the station. The type of power meters are PS194p-2x1. The unit power meter has CTs with 1200/5 and PT with 400/110. What could be the issue with the these digital power meters? or could it be where they are getting the signal from?
