Rule 2

Question 1

What is rule 2

Answer 1

• approach to exposed HV conductors and insulators

Question 2

What is rule 2.1

Answer 2

Individuals shall not allow any part of their body or objects to approach with specified SAFETY DISTANCE to expose HV conductors.

Question 3

What is rule 2.2

Answer 3

• POI’s established
• HV conductors could still be charged at High voltage
• Only objects permitted to encroach safety distance ( within zone established points of isolation)
• voltage type measuring devices

And

• earthing devices and associated application device.

Question 4

What is rule 2.3a

Answer 4

• POI’s established
• danger excluded by application of earthing device WZE POI
• encroachment Within specified SD is permitted under an appropriate safety document

Question 5

What is rule 2.3b.1

Answer 5

Encroachment permitted within safety distance without a document

1. -POI established for equipment in interlock cages
   
   • NRP to maintain safety distance WZE POI’s
     - individuals may encroach no closer than 1 metre from exposed HV conductors for application/removal of (TRD)type registered devices ( R2.2)

Question 6

What is rule 2.4

Answer 6

Safety distances
Up to 33 - 0.8m
66kv - 1 m
132kv - 1.4m
275kv- 2.4m
400kv - 3.1m

• 300mm to be maintained from the part of insulators supporting exposed unearthed HV conductor which are outside specified safety distance.

Question 7

What is 2.3b.2

Answer 7

2. POI established in indoor 132kv subs WNRP to maintain safety distance WZE POI’s
   - individuals may encroach to apply/remove TRD to the bus bar isolators, bus coupler and bus section isolators.
   - providing HV conductor to be approached is earth via a fully rated earthing device.
