HVgrand staff installed and commissioned the combination wave generator successfully in Spain SPD customer in June,2016. This product can output 20kV 10kA combination wave and 20kA 8/20μs, which can test Class II and Class III SPDs.
With the residual voltage divider, it can measure the residual voltage of SPDs.
Combination wave generator is equipped with automatic control and measurement system with American Tektronix oscilloscope, Japan Mitsubishi PLC and American Pearson current monitor.
