Vacuum Bottle Tester – VABO-80 / VABO-80B
The VABO-80 and VABO-80B are portable high-voltage testers by HighTest for testing vacuum switches (vacuum bottles) up to 80 kV DC. With adjustable test voltage from 10 to 80 kV in 1 kV steps, automatic pass/fail assessment based on leakage current limits, and a built-in thermal printer for instant field reports. The VABO-80B adds a 14.4 V Li-Ion battery for fully mains-independent operation.
Applications
- Periodic testing of vacuum switches in medium-voltage installations to prevent unexpected failures
- Field maintenance of switchgear at utilities, industrial plants, and commercial facilities
- Acceptance testing after overhaul or replacement of vacuum interrupters
- Inspection of circuit breakers following short-circuit events or overload conditions
- Quality control at manufacturers and service workshops for switching equipment
- Fault diagnosis of non-switching or suspect vacuum bottles
- Mobile inspection tasks where mains power is unavailable (VABO-80B with battery)
- On-site documentation and reporting of test results via built-in thermal printer
Key features
- Adjustable test voltage from 10 to 80 kV DC in 1 kV steps
- Accuracy ±2% (20–80 kV) and ±3% (10 kV)
- Adjustable test duration from 5 seconds to 2 minutes
- Automatic pass/fail assessment based on selectable leakage current limit (100, 200 or 300 µA)
- Visual and audible alarm on leakage current threshold exceedance
- Built-in 2.25″ thermal printer for immediate field reporting
- Storage of up to 200 test records in internal memory
- Data transfer to PC via USB and DMP software (HighTest)
- 4.3″ TFT colour touchscreen with intuitive menu
- Powered by mains or optional 14.4 V Li-Ion battery (VABO-80B)
- Compact and portable: 318 × 249 × 203 mm, field-ready design
