The AC Voltage Test Set T 22/1 is a portable test set consisting 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 VDE 0670)
• DC voltage testing of cables, cable fittings, installations and equipment up to 80 kV using a rectifier attachment

Technical Feature:

• Continuous testing with AC voltages 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 insulating gas (SF 6) 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.

Accessories:

• 80 kV DC voltage testing (Accessories are not included)
