We has developed DST transformer oil tester according to
International standard IEC156, which is developed especially for
measurement of insulating oil's breakdown voltage. The dielectric
breakdown is an indication of the oil’s ability to withstand
electrical stress. The oil sample is placed in a test cup and an AC
voltage is impressed on it. The electrodes are two discs, exactly 1
in. in diameter and placed 0.10 in. apart.
The voltage is raised at a constant rate, until an arc jumps
through the oil between the two electrodes. The voltage at which
the arc occurs is considered the dielectric strength of the oil.
DST automatic transformer oil tester is unique in the market due to
its functionality and the excellent user benefit in comparison to
costs. The transformer oil tester provides delivers clear and
reliable measurement results. It is no longer necessary to send
samples to the laboratory. Environmental and transport influence on
the samples are minimized. Due to its design, the tester is
particularly handy, easy to operate and especially excellent to use
under tough ambient conditions. By proper programming, DST
transformer oil tester has got functions of auto boosting, step
down, stirring, display and print out. Portable type is available
for performing both levels of this test in the field.
