To find out whether the bottle of a vacuum circuit breaker is intact before returning it to service, a regulated high DC voltage is applied and the leakage current is compared with a limit, following ANSI/IEEE standardised DC test methods. The VIPO-85 does it automatically: up to 85 kV in 1 kV steps with 1.5% accuracy, leakage measurement from 0 to 400 µA with 1 µA resolution and a PASS or FAIL verdict at 100, 200 or 300 µA, with a built-in thermal printer and all cables connected inside the IP67 case.
VIPO-85 key data
- High-voltage output: 1.0 to 85.0 kV DC in 1 kV steps, 0.3 mA continuous at maximum voltage, 1.5% accuracy and less than 2% ripple between 20 and 85 kV.
- Leakage measurement: 0 to 400 µA with 1 µA resolution and 2% accuracy at full scale.
- Vacuum interrupter test: PASS or FAIL verdict against a user-set limit of 100, 200 or 300 µA, following ANSI/IEEE standardised DC test methods; test duration settable from 2 s to 2 min.
- HiPot mode: kV, µA and TΩ display, 85 kV / 300 µA continuous rating and stop limit from 25 to 300 µA in 25 µA steps.
- Safety: high-brightness visual indicator and audible alert while high voltage is present, and discharge in under 3 s.
- Records: storage for 200 tests, built-in thermal printer and transfer by USB flash drive, which is also used for firmware updates.
- In the field: 4.3-inch ultra-bright IPS touch screen that works with gloves, ready 2 s after power-up, 410 × 310 × 150 mm case with IP67 when closed and operation from 0 to +50 °C; 100-240 V AC supply or a 14.4 V Li-ion battery on the VIPO-85B version.
Advantages
The vacuum bottle, verified in minutes
A regulated DC voltage of 1 to 85 kV in 1 kV steps is applied to the interrupter; the leakage current is measured and shown as a clear PASS or FAIL against user-set limits of 100, 200 or 300 µA.
Also a compact DC hipot
In HiPot mode the instrument displays kV, µA and TΩ with a continuous 85 kV / 300 µA rating and a stop limit adjustable from 25 to 300 µA in 25 µA steps.
Ready in seconds
The 4.3-inch ultra-bright touch display works with gloves, the unit is ready two seconds after power-up and a built-in thermal printer documents the result on the spot.
Evidence you can keep
The instrument stores 200 tests and transfers them by USB flash drive, with a high-brightness indicator and audible alert whenever high voltage is present.
Built for the field
All cables stay connected inside the rugged case, which provides IP67 protection when closed; the unit weighs 9.4 kg and works from 0 to +50 °C.
Applications
- Integrity testing of vacuum interrupters in medium-voltage breakers.
- DC hipot tests on switchgear, cables and insulation up to 85 kV.
- Commissioning and periodic maintenance in the field.
- Workshop acceptance tests with printed evidence.

Frequently asked questions
How does it protect the operator during the test?
The VIPO-85 signals the presence of high voltage with a high-brightness indicator and an audible alert, and discharges the output in under 3 s at the end of the test. All cables stay connected inside the case, which is rated IP67 with the lid closed.
How long does it take to test each vacuum interrupter?
The VIPO-85 is ready 2 s after power-up, the test duration is set from 2 s to 2 min and discharge takes less than 3 s. Because the cables are stored connected in the case, you move from one breaker to the next without setting the instrument up again.
What does the PASS/FAIL verdict mean?
The instrument compares the measured leakage current with a user-set limit (100, 200 or 300 µA) and shows PASS or FAIL for the vacuum interrupter under test.
Up to what voltage does it test?
A regulated DC voltage adjustable from 1 to 85 kV in 1 kV steps, continuously rated at 0.3 mA.
Can it be used as a hipot tester?
Yes. HiPot mode shows kV, µA and TΩ with an 85 kV / 300 µA continuous rating and an adjustable stop limit.
How are results recorded?
The unit stores 200 tests, prints them on the built-in thermal printer and transfers them by USB flash drive.
Is there a battery version?
Yes, the VIPO-85B, with a user-replaceable 14.4 V Li-ion pack for field work without mains power.
