Prezentare si Metoda de testare
Majoritatea dispozitivelor de înaltă tensiune precum: transformatoare, cabluri, contactoare, captatoare, condensatoare şi redresoare, utilizeză pentru izolare electrică şi transfer termic aşa-numitele uleiuri electroizolante.
Pentru a asigura o lungă durată de funcţionare a echipamentelor electrice mai sus menţionate, se impune verificarea periodică a calitaţii uleiurilor electroizolante.
Cea mai importantă cerinţă pentru uleiurile electroizolante este ca rigiditatea dielectrică să fie cât mai ridicată.
Determinarea tensiunii de străpungere la uleiurile izolatoare reprezintă o metodă de detecţie timpurie a reducerii proprietăţilor izolante.

Avantaje
• Recomandat pentru toate fluidele izolatoare
• Întreruperea imediată a tensiunii înalte după apariţia fenomenului de străpungere
• Sistem de protecţie la depăşirea temperaturii cu întreruperea tensiunii de alimentare
Testerul asigură determinarea tensiunii de străpungere printr-o testare singulară sau multiplă.
Aparatul se compune în principal dintr-o carcasă, un afişaj digital, un compartiment al probei şi un motor ce acţionează un dispozitiv de agitare magnetica.
Amestecarea completă a uleiului este asigurată de o bară magnetică în interiorul vasului şi un dispozitiv de rotire aflat sub suportul probei.
Cu scopul de asigura securitatea operatorului, uşa de acces în camera probei este asigurată cu un dispozitiv de blocare. De asemenea, în cazul unei împământări electrice necorespunzătoare un dispozitiv de siguranţă blochează butonul de start.

Kit de calibrare / Callibration Kit :: Cod produs C-80 (C-100)

Main features
An Oil tester both A and M series of OLT 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 tester’s 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 tester. A PC-connectivity makes it easy to collect data from OLT 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.
