Development of newly designed current transformers ТОЛ-Э-12 completed, the pilot batch manufactured.


The new design implements taps (100%, 50%) in the measuring and relay windings, that allows, in case of change the typical (maximum) current, flowing in the primary circuit, to adjust current transformer for measuring current values, achieving thus the accuracy enhance and the protection reliability. Current transformers are available in accuracy class 0,2S-0,5S-5P-5P based on the electrical steel core with reduced weight and dimensions.
