Figure 14 Proof A test operate menu 

If button “Run” is selected, tester output a voltage which is close to set voltage. And then stay for 
“stay time”. If there is no breakdown in the whole process, Figure 15 will be shown at screen. 

 

Figure 15 result of proof A test 

If the sample was breakdown, the breakdown voltage will be record and test failed will be show. 

The difference of proof A and proof B is that proof A is end when test is passed. But for proof B 

test,  Tester  will  rise  the  test  voltage  at  the  rate  of  2kv/sec  until  breakdown  and  then  shows  the 

breakdown voltage at screen. .     

2.12 Temperature Measurement 

Temperature Sensor PT100 is installed at the bottom of the test vessel as figure 15a. The resistance 

value of PT100 is depends on the temperature of its surface which is keeping contact with the test
