High Voltage Cable Test Set - DC

HV insulation under full control

The Ares-120 DC device is universal high voltage tester. It is extremely robust, but also lightweight, compact and easily portable thanks to a transport case on wheels. Capacitive loads, such as shielded power cables, will be properly and automatically discharged in case of an error or at the end of testing time by the integrated discharge device.

Key switch, switch-on interlock and a protective ground circuit ensure maximum safety.

Features

• Easy operation
• Robust construction, low weight
• Integrated timer:
  • max. 60 min 
• •Discharge device:
  • external ground-discharge rod 
• Voltage measurement direct at HV output
• Short-circuit-proof output:
  • protection by overcurrent tripping
• Protective ground connection

Fields of application

• Testing at recommissioning of cable systems after maintenance and repair
• Testing of newly installed cables an cable joints before commissioning
• Regular preventive cable testing 
• Testing of electrical equipment
