Simulation Specialist - Bushings

• The core of the role involves performing complex simulations to predict how a bushing will behave under extreme stress.

• Mapping electric field distributions to prevent corona discharge and insulation breakdown. 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.

• Living Hitachi Energy’s core values of safety and integrity, taking responsibility for your actions while caring for colleagues and the business.
