Attentionshould take 

1. Don’ttouch the metal parts during the measurement test to avoidelectrically damaging.

2. Wiring must be strictly measured by manual operation.

3. Be sure to carefully check before the test parameters setcorrectly.

4. Best to use a grounded outlet.

5. Do not limit the voltage and current in case excessivework.

6. Short circuit test, the non-pressurized side must be well short,or would affect the test results.

7. Do short-circuit test, if high or medium voltage side with anannular bushing current transformer, current transformer beforetesting the secondary side must be shorted.

8. Test wiring work must be grounded in the test line in the case,to prevent induced voltage electric shock. All short circuit,grounding and wire should have sufficient cross-section, and mustbe firmly connected. Test organization working to tight, smoothcommunication, in order to ensure the smooth progress of worksafety testing.
