Wolf River Electric begins by reviewing the site layout, event history, and performance concerns to understand the situation and the questions that need to be answered. A sampling strategy is then developed to balance confidence and cost, with additional focus placed on high risk or visibly impacted areas when appropriate. EL imaging is performed in the field, typically at night, using specialized infrared equipment. The captured images are analyzed by experienced professionals who classify defect types, assess severity, and correlate findings to system layout. The final deliverable is a clear, defensible report that supports owners, insurers, and stakeholders in making informed decisions.
