Weidmann Insulation Technology
Transformers used in renewable energy generation applications are subject to unique and demanding stresses, including highly variable loads, wide temperature variations, space limitations, and power quality issues. These specific conditions are significantly different from those of a “standard” distribution system transformer, and often result in increased thermal and electrical stresses on the transformer insulation system, which leads to premature aging or failure of this critical asset. We offer our customers a wide range of enhanced thermal class materials that can improve the performance and life of transformers used in renewable energy generation.

Technical Services
Critical to ensuring the successful operation of renewable energy plants is maximizing up-time and efficiency of the site. Preventative maintenance plans, understanding the condition of assets, and reacting quickly to analyze and diagnose failures is crucial.
Our Technical Services group have performed a range of services at renewable energy plants including fleet and condition assessments to identify potential issues and loss of life on transformers in the field, specification support to ensure that transformers ordered can handle the demanding environment they will be operating in, along with failure analysis when the worst happens.

Online monitoring of a transformer or network can form a key part of an advanced maintenance plan, increasing your ability to maximize up-time through prioritizing predictive maintenance actions. Not only does this increase efficiency, but it also enables the operator to use accessible data to manage the utilization of assets more effectively.
