kdown. This includes calculating the E_{max} (maximum electric field) at shield ends and condenser layers.

Simulating "skin effect" and ohmic heating in the conductor to ensure the bushing operates within thermal limits (IEC/IEEE standards).
Evaluating the structural integrity of porcelain or composite insulators against cantilever loads, wind pressure, and seismic vibrations.
Designing the optimal radial and axial distribution of capacitive layers (fine-tuning the length and diameter of aluminium foils) to achieve a uniform electric field.
Simulating the performance of different insulation media, such as Oil-Impregnated Paper (OIP), Resin-Impregnated Paper (RIP), or Resin-Impregnated Synthetics (RIS).
Type Test Simulation: Virtually replicating BIL (Basic Insulation Level) lightning impulses and power-frequency withstand tests.
Root Cause Analysis: Using simulation to investigate failures during real-world testing or field operations to identify design flaws.
You will be ensuring compliance with applicable external and internal regulations, procedures, and guidelines.
