Project Description

VABO-80B Brochure

VABO-80B is designed using advanced engineering technology to test circuit-breaker vacuum bottles up to 80 kV DC. VABO-80B has fast, easy and accurate measurement features with its user-friendly software. VABO-80B is a battery-powered device, which allows users to perform tests even without power supply during field tests.

The user can select the test voltages from 10kV to 80kV DC with step voltages of 1kV and the test time can be defined by the user from 5 seconds to 2 minutes. The leakage current preset values of VABO-80B are 100 µA, 200 µA and 300 µA. After setting the output voltage and test time with a predefined cutoff for leakage current, the test can be performed. After the execution of the test, if the leakage current doesn’t exceed the preset leakage current value, then the screen will show “TEST PASSED”. In the case, if the leakage current exceeds the preset value, then the voltage will be immediately turned off and shows “TEST FAILED” on the screen. In the case of HV presence, the HV indicator on the device illuminates with an audible tone.

VABO-80B features with a 4.3-inch large colour touch display, which is visible under both bright sunlight as well as dim light conditions. With the HighTest Data Management Platform (DMP Software), users can analyse and manage measurement results on PCs. Operators can easily print the measurement results with the 2.25-inch built-in printer of VABO-80B. The results can also save to a USB flash drive or to the device’s internal memory.  Multi-language capability and user-friendly operation menu make it easy to control VABO-80B. VABO-80B is a light-weight, compact and rugged device with the protection of IP67 (case closed) which makes it perfect for field tests.


Fast and reliable protection is the most important in case of any faults occurring in the electric power system. If the circuit breaker does not succeed in clearing the fault at the appropriate moment, the resulting accident can be dangerous in terms of both personnel injury and equipment damage and causing heavy losses.

Even though circuit breakers can be very reliable, they tend to gather dirt, moisture, and contaminants on the poles and on the exterior surface of the interrupter which may cause insecurity during operation, and once the air find its way into the interrupter and leakage starts to appear, the vacuum bottle becomes unreliable.

For the above mentioned reasons and more, vacuum bottle interrupters must be tested and maintained to ensure proper operation during electrical faults. Insulation integrity test is recommended by the manufacturers of circuit breakers and well documented in international test standards as IEC and IEEE.

Testing high voltage circuit breakers present a series of challenges. HighTest’s knowledge and unrivalled experience within the power circuit breaker industry resulted in the VABO-80B. This lightweight and impressive device tests vacuum interrupters by applying DC high voltage up to 80 kV.
