Location:Bad Honnef, North Rhine-Westphalia, GermanyJob ID:R0104799Date Posted: Company Name:HITACHI ENERGY GERMANY AGProfession (Job Category):OtherJob Schedule:Full timeRemote:NoJob Description:The opportunityU nderstanding the moisture dynamics in transformer insulation is critical for predicting aging, dielectric failure, and overallreliability. While recent models like the Thermo-Chemical Digital Twin offer advanced simulation capabilities, one of the mainopportunities for improvement lies in the modeling non-uniform water distribution and its impact on voltage behavior undertransient conditions. Additionally, no established criterion exists for evaluating water content in paper insulation underenergized conditions.Your responsibilitiesModel Development: Extend the water diffusion model to include spatially resolved moisture dynamics and additional influencing factors such as temperature gradients and oil agingDiagnostic Criteria: Develop a practical criterion for evaluating water content in paper insulation under energized conditionsVoltage Behavior Analysis: Investigate how increased and non-uniform moisture distribution affects voltage response under impulse and switching conditionsValidation: Validate model improvements through simulations and comparison with Breakdown Voltage (BDV) tests using special wave shapesYour backgroundMaster's student in Electrical Engineering, Power Systems, Applied Physics, or related fieldsStrong foundation in modeling and simulation (e.g., MATLAB, Python, COMSOL)Knowledge of dielectric materials and transformer insulation systemsAnalytical and independent working styleFluent in English; German is a plusWhat we offerS upervision by experienced R&D professionalsAccess to internal models, data, and simulation toolsOpportunity to contribute to cutting-edge transformer diagnosticsPotential for follow-up opportunities in research or engineering rolesswitching conditionsQualified individuals with a disability may request a reasonable accommodation if you are unable or limited in your ability to use or access the Hitachi Energy career site as a result of your disability.
