PENGUJIAN TEGANGAN TEMBUS ISOLASI MINYAK TRANSFORMATOR FASILITAS GEDUNG REKTORAT UNIVERSITAS AIRLANGGA SURABAYA
ABSTRACT: Testing of
transformer insulating oil breakdown voltage Rectorate Building Facilities
Airlangga University Surabaya conducted to determine the stability and
viability of the transformer oil. Transformer oil samples taken half a liter,
then the oil is placed in the test apparatus using Megger Type OTS60PB. This
was repeated at intervals of 30 seconds, each time of testing performed six
times, and the results taken average prices. This tester has two electrodes
with a diameter of 12.5 mm, voltage is applied gradually (every second 2 kV
ranging from zero to jump the fire occurred). From the test results obtained by
the average value of breakdown voltage isolation transformer oil at a temperature
of 30oC prior to treatment of 22.4 kV / 2.5 mm with oil colors on figure 2
(still good), and amounted to 72.05 kV / 2.5 mm after treatment (SPLN'50 -1982
and IEC No. 56 in 1991 standard ie ≥ 30 kV / 2.5 mm)
