DEM191 anti-steal single phase kWh meter is our latest designed product. It has only one inductor but has several properties of anti-steal. So it is used extensively by Electric Power Department to measure power in family. All technical targets are completely conformed National standard GB/T15283-94 and International Standard IEC60521.

Function and features:
 
1. It has a group of supplementary coil more than ordinary meter to be complicated with its measuring circuits.
      2. Its register is indirection and use the transmission ratio between positive and negative.
      3. It can resist stealing power supply as following; to earth, reverse connection, separate current, from condenser.
      4. Its function and connection circuits are the same as ordinary meter under the correct operating.
