Dielectric breakdown testing is performed to assess the ability of insulation material to tolerate high-voltage stress without electrical breakdown. The test measures the maximum voltage an insulator can withstand before puncture of the insulation occurs, making the insulation unable to inhibit current flow through the failure region.
Parameters that can be adjusted:
- Method of voltage application (Short-Time, Step-by-Step, or Slow Rate-of-Rise)
- Voltage rate-of-rise
- Electrodes
