It is mainly used to test the breakdown strength and withstand voltage time of solid insulating materials such as plastics, films, resins, mica, ceramics, glass, and insulating varnishes under AC (power frequency) or DC voltage.
The Voltage Breakdown Tester complies with standards:
GB1408-2006: Methods of test for electric strength of insulating materials
GB/T1695-2005: Test method for power frequency breakdown strength and withstand voltage strength of vulcanized rubber
GB/T3333: Power frequency breakdown test method for cable paper
HG/T3330: Breakdown strength test method for insulating varnish films
GB12656: Power frequency breakdown test method for capacitor paper
ASTM D149: Standard test method for dielectric breakdown voltage
Real-time test curve plotting with multi-color overlapping comparison.
Editable and modifiable test data for flexible applications.
Automatic storage of test conditions and results.
Flexible test report formats to meet various user requirements.
Manual validation of effective/invalid curve data within a test group.
Export of test results to Excel.
User and project management functions, ensuring data security and personalized settings.
Testing is performed inside a sealed chamber; when the chamber door is open, no high voltage is applied.
Safe electrode distance:
≥370 mm for 100 kV models
≥250 mm for 50 kV models
Independent protective grounding line to reduce electromagnetic interference and prevent computer malfunction.
Multi-level circuit protection: overcurrent, undervoltage, leakage, short-circuit, DC discharge alarm.
DC discharge alarm: After DC tests, the system alarms until the discharge device is used, ensuring operator safety.
Integrated discharge device eliminates the need for a separate discharge rod.
