Breakdown-Voltage Testing Device
Type HSV 824-3 / 824-05

Device for determining the insulation effect or breakdown-voltage of insulated copper conductors and similar products.

• Simultaneous testing of up to 5 test objects
• Test voltage: up to 20,000V AC
• Quick and safe contacting of straight and curved conductors using a ball bath
• Freely definable test profiles (voltage profiles)
• Einstellbare Breakdown sensitivity
• Independent high voltage sources
• Easy parameterization and operation
• Automatic test sequence
• Automatic unloading of the test object after each test
• High operational reliability even in harsh industrial environments


Standard version
  • Device with 3 test sections (triple device)
  • 1 ball bath per test section for contacting straight and curved test objects
  • User interface: DE, EN
Options and Accessories
  • Device with 5 test sections (5-way device)
  • Additional water baths to the ball baths
  • User interface: other languages on request
Process input
  • Insulated copper conductors (copper rods, magnetic wires, CTC or similar products)
Process flow and detailsTest procedure
  • Insert straight or curved specimens in ball baths and contact them
  • Close the cover of the test chamber
