Transformer Oil Temperature Measurement during Breakdown Voltage Test by GDYJ-502A

GDYJ-502A Transformer Oil Breakdown Voltage BDV Tester is used to measure breakdown voltage of transformer oil. It can also measure oil temperature during test. The test standards are IEC60156, IS6792, BS5874, ASTM D1816 and ASTM D877.

Temperature Sensor PT100 is installed at the bottom of the test vessel as figure. The resistance value of PT100 is depends on the temperature of its surface which is keeping contact with the test vessel when testing. GDYJ-502A will calculate the oil temperature in the oil test vessel according to the resistance value measured from PT100.
