CYEVT1-24 Electronic Voltage Transformer

Product Overview

The products accord with standard IEC60044-8 , GB/T20840.8-2007, and can meet customer’s other special requirement. The products use Rogowski winding to test current, mainly used in ≤ 35kV switchgear, match with electric instrument, digital measure and protective equipment, can at the same time realize multi-functions such as measure, control, protection and data transmission etc, secondary open circuit can not produce high voltage.
