1.3.1 General safety procedures prior to testing

When working under high voltage conditions, following topics need to be considered strictly prior to the
measurement set-up and testing.
1. The operators must have read the safety instructions and passed the local site safety instructions regard-
ing health and possible hazards.
2. The sample to be tested must be offline, de-energised, and grounded.
3. Each operator has to check the safety conditions together with the site responsible and pass the tagout/
lockout procedure for the specimen to be tested.
4. After the tagout/lockout procedure, the specimen needs to be checked for the presence of voltage to-
gether with the site responsible by using a suitable HV tester.
5. The operator has to check the solid work grounding together with the site responsible.
6. After passing issues 1) to 5), the specimen is in safe condition and may be connected to the equipment.
7. Check for a safe area as close as possible to the specimen terminals to install the equipment.
8. Apply demarcation around the full measurement set-up and make use of a safety guard, if necessary.
9. Prevent working alone.
10. Only authorised personnel are allowed to access the demarcated test area.
11. Hold a meeting with other people working close to the hazardous area before energising the test speci-
men.
12. Please check at least the insulation resistance prior to apply external HV potential.
13. Remove the calibrator before applying any external high voltage.
14. When applying external high voltage, carefully increase the voltage while observing if voltage and current
stay within predefined limits.
15. Make sure that the sample is free of voltage after the external high voltage has been switched off.
16. Discharge and ground the test specimen with a grounding stick before changing or touching any HV
connection.
17. The specimen is now in safe condition, necessary changes to the set-up can be done safely.
Please check the detailed Power Diagnostix "Health and Safety Instructions and Recommendations" guide-
line in case of any ambiguities regarding safety.
