Research Associate (m/f/d) - Keyword: DFG - Earthing

As part of the research project, the influence of earthing systems on the formation of the single-pole frequency-dependent residual current in networks is being investigated and evaluated. The aim is to determine the contact and earthing voltages as a function of the harmonic components in the fault current for networks with resonant star-point earthing. In particular, the following tasks are to be addressed:

• Frequency dependence of the impedances Z(f) acting in the earthing system,
• Influence of the reduced earth current depth _δE(f) of short line sections and the non-ideal parallel routing (inclined arrangements) of the meshes on the field distribution and electromagnetic coupling,
• Mathematical description and modeling of the earthing system of low-voltage grids and other infrastructures,
• Consideration of other or mixed grid forms,
• Frequency dependence of the resulting reduction factors r(f),
• Evaluation of lines without a reduction conductor or its interruption,
• Evaluation of earthing measures with regard to RESPE networks with a high harmonic content in the residual earth fault current_IRES.

The following knowledge and skills are required

• Completed university degree in the field of electrical engineering with specialization in the field of energy systems,
• Practical professional experience, in particular special knowledge in the areas of neutral point treatment and measurement in distribution grids,
• practical knowledge or experience with MatLab and PSCAD, in carrying out measurements and simulating transient balancing processes, and
• very good German and English language skills.

In addition, the following are desirable

• Project and research experience.

We expect from you

• a high level of interest in scientific tasks
• a reliable, committed, loyal, team-oriented and independent way of working,
• Willingness and interest in further professional and personal development and
• Willingness to undertake business trips.
