America’s onshore and offshore renewable markets will need to double each year to meet clean energy objectives. IMCORP’s ability to provide a diagnostic medium and high voltage cable partial discharge test at 50/60 hertz will reduce exposure of unplanned outages associated with substandard cable systems. Our ability to pin-point the source/location of defects not meeting manufactures’ quality control standards, provides our clients with knowledge of the craftmanship and manufacturer quality. Our Factory Grade® test report provides a foot-by-foot assessment that enables our clients to understand potential risk of new and aging renewable cable systems.
