Billing measurements of electrical energy in Germany A complicated issue For billing measurement of electrical energy in Germany, at higher currents and voltages that are no longer controlled by the energy meter, inductive current and voltage transformers are used without exception. These devices are subject to the transformer principle. While current transformers represent a transformer…

Power quality measurements in all EVU voltage levels up to 150 kHz – Is that possible? A reliable energy supply has become an important location factor for many companies.While grid failures and voltage fluctuations were among the most important parameters of supply quality in the past, voltage transients and voltage transients or voltage harmonics are…
