The user can select the test voltages from 5 kV to 80 kV DC with step voltages of 1 kV 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 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.
WHY DO WE TEST VACUUM BOTTLE INTERRUPTER?
Fast and reliable protection are the most important in case of any faults occurs 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 finds its way in the interrupter and leakage starts to appear, the vacuum bottle becomes unreliable. For the mentioned above reasons and more, Vacuum bottle interrupter must be tested and maintained to ensure proper operation during electrical faults. An 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.
