

Job Risk Analysis must be done by the work team before commencing any switching and tests near the underground cables and all parties concerned are in agreement upon that assessment



The tester in charge shall ensure that drawings are made available to familiarize himself with the work area and equipment locations prior to commencing work



Ensure to connect a local earth on the test equipment, if practicable. The case earth must remain connected to the system earth in order to maintain an acceptable single earth potential



After the cable is tested (SI, IR and VLF) cable cores must be then discharged. If applicable, close the Earth switch and then the test set leads may be removed



PPE Requirement:



Use suitable barriers, barricades and warning signs on both sides of the cable to prevent access to the cable by persons not involved with the testing. If there is any danger of exposing the public or staff to energized conductors or equipment a safety observer must be used.


