Need to measure power and energy on a medium voltage system? Think your only choice is to use fully rated current transformers?
When measuring power and energy on a medium voltage system, you might think you can only use a fully rated potential transformer & current transformer but that would be wrong. The challenge is that medium voltage current transformers are extremely invasive. The installation of the CT requires a series connection, which in turn, requires the removal of a section of cable or bus bar for installation.
Consider using Flex-Core® low voltage current transformers to make installation a breeze. All that your licensed medium voltage electrician needs to do is install the current transformer over a FULLY insulated cable or bushing. The cable / bushing insulation will isolate the CT, secondary windings, and the connected meter from the higher voltage. This transformer scenario will save money, time, and frustration that you're sure to experience with a medium voltage CT.
