Oil testers bring out accurate and repeatable results of measured breakdown voltage. Fast high-voltage switch off time makes it possible to carry out test of dielectric liquids, which are easily destroyed under such influences. The internal design of OLT testers combined with a use of automatic high voltage breakers, cutting off supplied voltage if testers lid has been opened during the test, provide operator with high level of safety. Testers are fully equipped and are ready for operation right after unpacking. They come with a test vessel (IEC 60156 basic configuration) with VDE 0370 mushroom-shape electrodes. A gap between electrodes is easily regulated with a use of pass-no pass gauge, which comes in pack. A-series provides with fully automatic test procedure according to selected standard (basically IEC 60156 and GOST 6581 settings are preloaded). It has a built-in printer which is able to print a test report after procedure is done. Test results are saved into non-volatile memory of OLT oil tester. A PC-connectivity makes it easy to collect data from OLT oil tester, save and store them as well as print a fulfilled report. Test voltage is being measured directly on electrodes. This fact combined with a true sine voltage shape (independent from supply voltage shape), increases repeatability and accuracy of measurements. Test vessel for this series goes with magnetic stirrer, which stirs a liquid between two measurements.

Automatic circuit breaker tester upa-3is designed for testing and ampere-second characterization of automatic ac current circuit breakers. The device allows registering the value of the supplied current and timing the automatic circuit breaker switch interval.Upa-3 is a mobile device, which could be easily transported to a required testing location.Upa-3 operates on the principle of varying the power in the primary circuit of the matching power transformer and, respectively, varying the output current, flowing through the automatic circuit breaker under the test. Power regulation could be done either through an external regulator (rno or vr) or through a built-in thyristor controller.
