2. Transformation ratio test
2.1 wiring method
PT transformation ratio test wiring diagram
3. Angle difference ratio test
3.1 first step test transformation ratio
First, test the transformation ratio according to the wiring method in 1.1 according to the system prompts. Do not shut down after the completion of the test transformation ratio. Dismantle the wiring on the primary side according to the prompts and then carry out the second test;
3.2 second step test angle difference ratio difference
After the first test, remove the primary wiring according to the wiring prompts, and then press "-" to continue the test.
Note: during the transformation ratio and error test, there will be high voltage in the instrument. It is forbidden to change the wiring before the second test prompts wiring.
4. Load test

5. Result description
If the currently selected experimental project is completed, the device will automatically enter the result display interface as shown in the following figure:
Excitation curve result interface
Secondary resistance: the secondary DC resistance value of the current set temperature test;
Correction resistance: the resistance value corrected to the target temperature;
Transformation ratio: measured transformation ratio of current winding
Polarity: OK / - (homopolarity) or NOK / + (reverse polarity).
