MSVT Multi-Secondary Voltage Separating Transformer

MSVT Multi-Secondary Voltage Separating Transformer

  • Typical accuracy ±0.1%
  • Easy mounting
  • High output power
  • Integration with the ASTeL test system

The MSVT multi-secondary voltage separating transformer was designed for the galvanic separation of measuring circuits. Thanks to its unique winding technology, exceptional parameters are possible. A maximum ratio accuracy of less than ±0.1 % makes the instrument the ideal solution for a wide range of applications. Among them is the opportunity to use the MSVT transformer for testing electricity meters with closed I-P links, i.e., meters with connected current and potential circuits.

Designed for single-phase meter testing, the MSVT can be controlled either with a local switch or by the test bench control software. Software control, makes it possible to switch the test voltage on/off either from the voltage source and/or from the MSVT. It is also possible to bypass MSVT during testing.
