This type of voltage transformer Following the three-phase five-column voltage transformer ,to eliminate lead to the transformer ferromagnetic resonance due to the varying degrees of power system grounding burned a lot of that scourge and developed a new type of voltage transformer.
This type of transformer -based epoxy resins and special insulation material insulation,exterior to protect the metal box and porcelain sets,to improve the moisture resistance and electrical insulation properties .
And it is not afraid of sub-frequency ,not voltage burned，long-running line of single-phase case，without overtemperature consider,while protecting the windings of the voltage 100V to promote the relay work.
