2. Resolution test
Usually set the divider value during 0.1000000~0.0999900 which mean turn ratio to be 10.000~11.100. The display value of the ratio tester should obviously change when the divider set value changes.
3. straight-through test
It means the test when divider set value is 1.000000. When make this test, the primary UAB will be directly connected with secondary terminal ( a, b terminal), that is to say, UAB=Uab. It is 1/1 self-checking. But when the ratio tester is the type for which such straight test are not allowed, inductive isolated winding can be used to do 1/1 isolation test.
4. Ratio group test
The standard three phase PT can make 12 groups for group testing of the ratio tester. Turns ratio can be 10 or 100 or 1000 total 3 choices. PT each single phase error less than 0.05%
