  • Method of correcting inaccurate instrumental potential transformer ratio
    Patent number: 4607211
    Abstract: To compensate for voltage ratio errors in a cascaded core instrument potential transformer, the coils of an outer coupling winding otherwise utilized to magnetically couple an adjacent pair of cores together are electrically connected into the primary winding circuit to either add its turns to or subtract its turns from the primary winding turns in order to bring the secondary winding output voltage within acceptable accuracy tolerance limits.
