Three phase meters



Three phase electric meters type MV are products complying with the international standard IEC60521. They are manufactured by moder technology line and equipments, ensured quality according to ISO9001:2000.


Three phase electric meters type MV have high performance and high reliability. They are built for measurement active energy (kWh) or reactive energy (kVARh) in alternating current three-phase three-wire or three-phase four-wire networks. They consist of two-element and three-element meters.

They comply with class 1 or 2 specifications of the international standards IEC60521. They are chacracterized by the following features:

  • Simple adjustment.
  • High torque.
  • Low friction.
  • Low starting current.
  • Low power consumption.
  • Low temperature coefficient.
  • High stability.
  • High resistance to short circuits.
  • High resistance to surge voltage.
  • High dielectric strength.
  • Double jewel or magnectic lower bearing.
  • Prevent electric steal: Non-reverse running device or Uni-directional register.
