注意事项

1．在测量过程中一定不要接触测试线的金属部分，以避免被电击伤。

2．测量接线一定要严格按说明书操作，否则后果自负。

3．测试之前一定要认真检查设置的参数是否正确。

4．使用有地线的电源插座。

5．不能在电压和电流过量限的情况下工作。

6．短路试验时，非加压侧的短接必须良好，否则会对测试结果有影响。

7．做短路试验时，如果高压或中压侧出线套管装有环形电流互感器时，试验前电流互感器的二次侧一定要短接。

8．试验接线工作必须在被试线路接地的情况下进行，防止感应电压触电。所有短路、接地和引线都应有足够的截面，且必须连接牢靠。测试组织工作要严密，通信顺畅，以保证测试工作安全顺利进行。

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.
