The KEP OLT-80A Oil Breakdown Tester allows 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 KEP OLT-80A Oil Breakdown Tester combined with a use of automatic high voltage breakers, cutting off supplied voltage if tester’s lid has been opened during the test, provide operator with high level of safety.
The KEP OLT-80A Oil Breakdown Tester comes fully equipped and are ready for operation immediately after unpacking. It comes supplied 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.
The KEP OLT-80A provides a 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 the KEP OLT-80A oil tester. A PC-connectivity makes it easy to collect data from the OLT-80A, 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.
The Test Vessel for the KEP OLT-80A Oil Breakdown Tester is supplied with a magnetic stirrer, which stirs a liquid between measurements.
