Attention should take
1. Don’t touch the metal parts during the measurement test to avoid electrically damaging.
2. Wiring must be strictly measured by manual operation.
3. Be sure to carefully check before the test parameters set correctly.
4. Best to use a grounded outlet.
5. Do not limit the voltage and current in case excessive work.
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 an annular bushing current transformer, current transformer before testing 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 shouldhavesufficientcross-section, and must be firmly connected. Test organization working to tight, smooth communication, in order to ensure the smooth progress of work safety testing.
