Electronics Thansducer Used In Medium Voltage Assemble Products

Current and voltage transducer are the mandatory instruments for energy measurement and relay protection function in the electric power system.But for so many years,in medium voltage distribution network system there was also the conventional electro-magnetic CT/VT transducers be used widely,the strategy of Smart power Grid is to make the electric system be digital:and intelligent,to buld digitalized substation,so the conventional electro-magnetic CT/VT transducers show several unsolvable drawbacks,and could not satisfy the requirement of the modern power system and more.Based on the analysis of current development of electronic current/voltage transducers and presently available techniques,the resistor-divider voltage transducers and the Rogowski-coil current transducer was chosen for our electronic current/voltage transducer.Intruduce Rogowski coil, low power coil and a resistor capacitor electronic current and voltage transducers.Through exchanges and cooperation with transformer manufacturers introduced several currently used for electronic transformers, medium voltage distribution network system and analysis of its performance parameters.Introduction and application of electronic transformer in MV complete sets of products and intelligent equipment.
