SMD-3 ( three-phase isolating current transformer for testing meters with closed U-I links)

SMD-3 is designed for use in MTS ME 3.1KM test system.


Three-phase isolating transformer provides galvanic isolation between current and voltage circuits of 3 single-phase electric energy meters with closed U-I links.  The front panel bears terminals for connecting meters under test and photoelectric scanning head (or Pulse Former).

The meters can be tested in semi-automatic or fully automatic mode (with use of 3 Current/Voltage-to-Frequency Converters, CVFC, and personal computer).
