Changes in Energy Technology – Part 1

In this article we discuss the current changes in the energy technology. In addition, we will look on the effects of grid repercussions and what influence they have on measuring devices with which we detect faults in the grid.

Performance increase in the distribution grid

Due to economic unreasonableness, grid operators are rejecting applications to connect PV systems in the low-voltage grid more often. The responsible grid planners are guided by the connection guideline VDE-AR-N 4105, in which decentralized generation facilities may only raise the voltage level in the low-voltage grid by 3% compared to the previous situation.

Parallel Charging of E-Vehicles

he Technische Hochschule Bingen (THB) charged e-vehicles in parallel at ten charging points. What was of interest here was measuring the charging current and its effect on the THB network; to determine pulse frequencies and their distribution across the network and to assess network asymmetries…

Evaluating Supraharmonics up to 150 kHz in E-Vehicles at TH Bingen

In the first part of the measurement campaign in 2016, various e-vehicles were assessed as to their charging behaviour and feedback to the network. The evaluation considered DC harmonics up to the 50th…

Power Quality Detectives

Modern measurement technology makes an important contribution to the power quality of low-voltage networks. Without it, we could not make statements about the quality of individual power characteristics, nor find the causes of faults. It was for this reason that the decision was taken in early 2001…
