Baoding Excellence Electric Co., Ltd. to tell you about the transformer capacity tester in the measurement process must not touch the metal part of the test line, in order to avoid being injured by electricity.

1. Measuring wiring must be operated strictly according to the instructions, otherwise the consequences shall be borne by you.

2. Before testing, make sure that the parameters set are correct.

3. It is good to use electrical outlets with ground cables.

4. Cannot operate under voltage and current overlimits.

5. During the short circuit test, the short connection of the non-pressurized side must be good, otherwise it will affect the test result.

6. During the short circuit test, if the high voltage or medium voltage side outlet bushing is equipped with annular current transformer, the secondary current transformer must be short-circuited before the test.

7. The test wiring shall be carried out under the condition of grounding of the tested line to prevent electric shock by induced voltage. All short circuits, grounding and leads shall have sufficient cross sections and shall be securely connected. The test organization should be strict and the communication should be smooth to ensure the smooth progress of the test work.

8. When the instrument needs to charge, be sure to turn off the power supply (press "O" to turn it off), plug in the power cord, the yellow light of charging indicator starts flashing, indicating that charging is in normal state.

9. When testing transformers of 500kVA or 630kVA, it is necessary to set the reference capacity, because transformers of 500 and 630 are in the impedance voltage conversion zone, and the capacity may cross. In order to avoid misjudgment, this parameter must be set.
