2.9ASTM D1816 TEST
The fifth item of the test selection menu is ASTM D1816. When this item is selected, tester will be
start in fixed parameters as Figure 11 The value of the parameters are “180s initial time”,””,
“Continuous stir time” and “60s wait time”. Rate of HV rising is 0.5kv/s in this test option. The
test will be repeated for 5 times in one ASTMD1816 test. The process and the test result are
similar to IEC156/IS6792/BS5874 .The test results of ASTMD1816 include breakdown voltages,
average voltage of breakdown voltages, standard deviation and oil temperature at the time of the
last breakdown. When the test is completed, you can print or save all the test results.

.
When this item is selected, tester
will be start in fixed parameters as Figure 11 The value of the parameters are “120s initial time”,””,
“No stir time” and “120s wait time”. Rate of HV rising is 3kv/s in this test option. The test will be
repeated for 5 times in one JIS C 2101-99(s) test. The test results of JIS C 2101-99(s) include
breakdown voltages, average voltage of breakdown voltages, standard deviation and oil
temperature at the time of the last breakdown. When the test is completed, you can print or save
all the test results.
