Since the dramatical incidents of Fukushima with the following nuclear disaster the German government has invested in renewable energy production and the planned shut-down of all nuclear power plants. This shutdown needs to be compensated by the European electrical grid as well as all renewable energy production facilities. Only High Voltage Direct Current (HVDC) is capable to deliver the transportation over wide distances of electrical power with reduced losses. By using HVDC technology all crucial aspects on the security of energy supplies have to be well known and taken into account.
The work of this PhD thesis will focus on this field of HVDC energy transportation.
In order to establish a superimposed measurement capability at the PTB, first the pure impulse side of the generation circuit will be evaluated. This is done at low voltages, beginning with corresponding calibrators and attenuators. Afterwards, with this equipment, the high voltage measurements validate these low voltage results.
At second, the HVDC voltage measurement capability is optimized, also beginning with low voltages at the 10 V level. With these results, all scale factors are extrapolated by linearity measurements to high voltages up to 1000 kV.
In the end the superimposed voltages are produced and measured by combining the impulse and HVDC insights. The superimposed divider including the coupling elements is researched by different measurement procedures. As a result, the high voltage measurement equipment is evaluated by the uncertainty estimation of the entire system.
