I am looking for a component for non-invasive (non-contact) coupling between a 11kV, 60Hz AC line (without neutral) and a current detector such as HCPL-0370 with a low voltage input of no more than 220V AC.
Current transformer might be an option but installation is difficult due to 11kV insulation requirement and cost, and it may need to break the line to get the line through. I need a simple and low profile coupler which can be directly fixed to the 11kV line without high insulation requirement.
