Technical & Field Services
We offer comprehensive support, including manufacturing process inspections, proposal process improvements, and competitive reviews. Our services extend to product development, substation and transformer engineering, design reviews, electrical, mechanical, structural, and seismic analysis. We also provide field and factory test witnessing, plant audits, design and manufacturing technology reviews, and quality assurance for both distribution and transmission electrical assets including power transformers, underground cables, Air and GIS switchgear, and overhead line equipment. Additionally, we assist with logistics, project management, standards certification, software development, and transformer design optimization. Our goal is to enhance efficiency and ensure the highest standards in transformer technology and service. Potencia Partners subject matter experts are capable of performing root cause failure analysis and investigations on LV, MV, and HV assets.
