Technical Specification: AC Voltage Test Set / T 22 / 1


Application:
The AC Voltage Test Set  T 22 / 1 is a portable test set. It consists of two separate units: The Control Unit and the High-voltage unit
This division enables the operator to use the test set on site without transport aids. The test set can be equipped with a rectifier attachment  for DC Voltage testing up to
80 kV.

The AC Voltage Test Set T 22 / 1 is used for:

  • AC Voltage testing of low capacity test objects (e.g. metal enclosed High-Voltage switchgear
    as per VDE0670)
  • DC Voltage testing of cables, cable fittings, installations, and equipment up to 80 kV using
    a rectifier attachment.

Salient features:

  • Continuous testing with AC Voltage up to 75 kV
    at 1 kVA
  • Set composed of function blocks:
    •   - T 22 / 124 control unit
      - T 22 / 12 SF6  gas transformer
      
  • Built-in overload protection
  • DC Voltage testing with rectifier attachment

Working Method:
A High-Voltage transformer insulated with un-insulating gas (SF6 ) produces a High-Voltage of 75 kV - rms.
This voltage is infinitely variable from 0 to 75 kV using
a regulating transformer: In the basic version for AC Voltage testing, the output voltage is calculated and indicated by measurement of the primary voltage of the High-Voltage transformer and conversion using the
turn factor M 402 measuring unit. DC Voltage is
produced using a rectifier attachment. Voltage measurement is then done using a separate
measuring resistor and the M 401 measuring unit.
