HPA 35...78

The AC voltage test sets HPA 35 to 78 are suitable for 50 Hz AC testing of test objects with a low capacity. In addition to 50 Hz AC testing these units can also be enhanced to a DC test set, (see DC-Test Systems).

Typical application areas: 

- Testing of switchgear 
- Testing of current-transformers
- Testing of MV plant/ component testing

All HPA test systems at a glance: 

- HPA 35, AC testing up to 35 kV_rms
- HPA 50 / 58 AC testing up to 50 / 58 kV_rms
- HPA 78, AC testing up to 78 kV_rms 

Key benefits:

• Compact, cast-resin high-voltage transformers
• Separate control and HV-units
• Voltage continuously adjustable
• Powerful system: 1,2 kVA continuous operation, up to 3 kVA 60 min. short-time operation
