Noninvasive Measurement of the network impedance for power quality assessment

Posted by Harald Weidl
On 16. August 2024

Abstract Due to a continuous increase in DC loads with power supplies, frequency converters for power and speed control or other non-linear loads, the harmonic levels in a network can increase to such an extent that a disturbance or an impermissible stress on other components occurs. Already in the planning phase it is therefore useful […]

Power Quality Measurements in all voltage levels of the energy utilities up to 150 kHz – Is it possible?

Posted by Harald Weidl
On 14. August 2024

A reliable energy supply has meanwhile become an important location factor for many companies. While power failures and voltage fluctuations were among the most important parameters of supply quality in the past, voltage transients and voltage harmonics are becoming more and more important. This is mainly due to the increasing number of non-linear loads and […]

On 15. July 2024

If an electric vehicle is charged at home some chargers operate in single phase mode.Some charging stations allow single-phase charging above the single-phase unbalanced load current limit.According to TOR the single phase current is limited with 16A in Austria and 20A (VDE-standard) in Germany. Different voltage levels on the three phases and a shifted neutral […]

Solar inverters with high voltage, large current, and high power are becoming increasingly common. This is done to increase power generation efficiency and reduce installation costs. This article introduces measurement of high voltages, large currents, and high power values when evaluating solar inverter efficiency. Solar inverters play a crucial role in converting electrical energy for […]

Fluxgate bushing transducers for highly accurate current measurement in the range from DC to 150 kHz on transformers

Posted by Neo Messtechnik
On 31. May 2023

Abstract The increasing market penetration of renewable energies is generally directly related to an increasing number of power electronic systems in the grid. Accordingly, a continuous change of the harmonic situation is to be expected depending on the operating state of the plants. Simulations are often not sufficient to represent the real situation of current […]
