HVDC MEASURE
Development of a sensor head, including research into fundamentally suitable electrode configurations for different voltage waveforms and ranges
The aim is to reliably measure direct, alternating and mixed voltages using the principle of the generator-type voltmeter. Examples of instruments for measuring potential and voltage include rotary voltmetres, in which a grounded arm opens and closes an electrode segment, so that a capacitive current is generated by the change in the area of the capacitor arrangement, from which the voltage to be measured can be deduced. The potential of metallic parts or charged surfaces is measured exclusively via the induced voltage at the measuring head with high impedance. The electrical power supply systems of the future will operate with alternating voltage and direct voltage, but also with superimposed voltage waveforms. Charges occur particularly in DC systems. These must be detected safely and without losses. Voltage dividers used to date require a measuring current and a metallic contact. This is avoided with the measuring principle to be developed further.
