High-Voltage Laboratory Division
Dielectric Breakdown
Testing
Comprehensive destructive and non-destructive analysis of insulation integrity under extreme electrical stress. Our automated laboratory environment simulates stratospheric conditions to identify critical failure points before deployment.
SCOPE CH1
verifiedLive Lab Feed ID: 882-AVP
Testing Phase Sequence
PHASE 01
Pre-stressing
Conditioning of the DUT (Device Under Test) within a vacuum-sealed environmental chamber.
PHASE 02
Field Alignment
Precise calibration of electrode geometry to eliminate parasitic discharge interference.
PHASE 03
Voltage Ramp
Incremental AC/DC load application (up to 250kV) monitoring leakage current in real-time.
PHASE 04
Failure Analysis
High-resolution micro-imaging of the breakdown site to determine morphological root cause.
