Electrical Engineer Designer

Electrical Designer

The Electrical Designer will be responsible for the electrical design and development of distribution transformers in compliance with IEEE, CSA, and customer specifications. This role requires a sound foundation of electrical engineering design principles as they pertain to the electrical requirements unique to transformer applications. This role involves preparation and review of detailed designs and calculations in accordance with applicable standards and manufacturing constraints.

Design and Development:

• Develop and validate transformer electrical configurations including high and low voltage winding arrangements (e.g., delta, wye, series/parallel), impedance, and insulation coordination for voltage classes up to 35 kV.

• Check electrical designs against material characteristics and performance criteria, such as:
• Core and Load losses
• Impedance and voltage regulation
• Flux and current densities
• Dielectric withstand and BIL

• Define and specify major components such as:
• Tap changers and Dual Voltage switches
• Bushings, arrestors and fusing
• Terminal arrangements and type, etc.
• Accessories such as PRDs, gauges, etc.

• Review and prepare, as applicable, technical design documents including:
• Connection diagrams
• Nameplate data
• Tap changer/switch wiring
• Bill of materials for electrical components

Standards and Compliance:

• Interpret and apply relevant industry standards (e.g. IEEE, CSA, and DOE) to ensure compliance.
• Participate in design reviews and root cause analysis of production or design issues.
• Contribute to standardization of transformer designs and development of design tools, templates, and best practices.
• Stay updated on evolving industry standards, participating in technical events as required.
• Support certification and testing requirements, such as losses, dielectric, short circuit and impulse testing.

Collaboration and Coordination:

• Coordinate with mechanical design to ensure compatibility of bushing locations, terminal clearances and component layout configurations.
• Collaborate with manufacturing, test, and quality teams to resolve non-conformances, implement engineering changes, and validate design improvements.
