Medium voltage instrument transformers
Medium voltage instrument transformers are to be installed in grids for voltage levels from 3,6 to 52 kV. They are insulated with oil impregnated paper or high quality epoxy resin. After cross-linking at high temperatures, the epoxy mixture takes on excellent insulating characteristics and required mechanical features. Transformers are designed in compliance with relevant standard.
There are four groups of medium voltage instrument transformers:
