Product Description

      Intelligent Dry Type Transformer Monitor is designed for the safe operation of dry transformer. It can automatically operates the fan's relay according to the temperature.By comparing current temperature with pre-selected temperature,monitor operates the alarm,trip relays to keep the transformer safe operation.
