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 […]
