Abstract
Optimization of the surface protection of transformers or inductive components, that are placed in humid ambients

Task description
Large distribution transforemrs, inductive components in the automotive area or for railway applications are exposed to difficult environment issues, like humidity or dirt. The surface protection has a high infleunce on the ageing and thus the lifetime of inductive components. We are developing a new surface protection with super hydrophobic characteristics similiar to the lotus effect.
Researches for appropriate materials have to be done. The items have to go through tests under multiple stress like humidity and electrical stress. Highvoltage measurements for partial discharge have to be done.

Requirements
Your are short before finishing university, electrical engineering

small, toroidal & power transformers, toroidals, one-phase-transformers, three-phase-transformers, PCB-transformers, chokes, HF-components

  • Calculation bases for saturation strong iron core chokes
  • Limits and possibilities of the calculation with standard software
  • Calculation via electromagnetic fields
  • Harmonics and peak current calculation

 

3) Optimization of inductive components - high voltage transformers

  • Research of the winding construction
  • Construction and influence of the iron core
  • HV winding grounding and its effects

4) Research of fields in high voltage transformers and high potential transformers
