How many strands gone? TGN 200, is the steel core exposed? what conductor is it? is it twin,triple or quad? what phase is it on? if its quad is it on the bottom conductors of the bundle? (each one of these questions enable you to move towards a solution)

Q

Why do we get circulating currents and when?

Q

Describe what a safe system of work is and what it contains?

A

The condition that exists to protect people from the inherent dangers of the system they are working on, SSOW contains safe access/egress, safe place and environment of work place, using safe methods of work and PPE this is all known as General safety and is catered for in the RAMS. Also system safety is taken care of by the issue of a safety document and application of the rules.

Q

When prepping a route of earthwire fitting replacements, 200+ towers, would you do a site visit on every one?

A

Yes where possible but most of the time its not practicable, group all suspension towers together, these can be done first while you check angles, cellular towers, terminals, tee-offs and any that are on private/industry land or out of the ordinary.

Q

What information does the CP need to give the CPO when requesting a DAR outage?

A

CCT Name, Route and TOGA reference

30
Q

Can CDM have more than one principle contractor?

A

Yes, they agree between them the boundaries for example OHL work is one and the substation is another.

31
Q

Can you apply a primary Earth?

A

No! (substation SAP job) can apply a DrESS scheme suitably rated to be converted to a primary earth by the CPS

32
Q

What conditions need to be in place before you can access the conductors and what rules and procedures apply?

A

Isolated at both ends and primary earths applied line side of the isolation, approach within safety distance is allowed under an appropriate safety document for the application of drain earths. safety rules 1-3, 6,7 and 8. NSI 1,2,4 and 6 and 8

33
Q

Can you work on the line end in the sub?

A

Yes but will need a substation SAP 6 and 8 or OHL SAP 6 and 8 to advise on the document prep and give access to the line end, then instruct demarcation requirements, once in place work can proceed within the safe working area.

34
Q

What is the process for managing migrant workers?

A

Ensure the CP speaks fluent English and native language of the team, so you can tell he fully understands the instructions and contents of the safety document and communicate it to them. In some cases where some of the team may be isolated from the rest then another member must also be English and native language, and on large scale projects there must be an independent translator available at all times to assist the SAP in his duties. All work ceases if the CP leaves site.

35
Q

Which department does your biannual audit?

A

SRAT

36
Q

37
Q

How would you deal with an emergency?

A

Risk Assess the site, keep people away and warn them, including police and fire brigade, contact TNCC and fault if necessary, request POI and PE at subs, liaise with police and fire brigade giving all information they need, arrange for site to be made safe if needed and then treat as a normal job (RAMS work pack etc) (depending on emergency)

38
Q

Why do we have SAP’s?

A

We have a duty of care under the H and SAW act 1974 to keep people safe when working on the system, one way we do that is by training people for defined tasks and ensuring competency in what they are asked to do.

39
Q

What words must an SAP never use??

A

Should, would, could or maybe!

40
Q

You are working on a terminal tower what earthing do you need? What about if that’s changing circuit plates?

44
Q

How would you manage painters?

A

RAMS up front well in advance of start date, request a competency matrix up front (NSI 4, BESC, P, CP & rescue) & drain earth test records, ensure coordination meetings are attended, give them access to sections of the route rather than the whole, QA their QA to highlight any issues, sensibly monitor them for compliance, stop the job if need be.

NSI 30 BESC, CBT refreshers completed, 1 unnanounced audit every 2 years, must attend SAP stand down days every year, complete an annual safety document review.

48
Q

List the schemes in stages start to finish, back it up in remarks section with a statement to follow sequence of earthing.

51
Q

What documents do you have in your SAP briefcase to carry out a job safely?

A

safety rules, NSI’s, AMBP’s, TGN’s, TP’s, TS’s

52
Q

What do you do as an SAP in a planning meeting?

A

Receive work, obtain job numbers, discuss complexity of the work, any issues such as work in the subs on safety precautions, DrESS requirements and dates!

53
Q

Why do we audit our SAP’s?

A
  • Legislation

56
Q

How is a substation DrESS made into a Primary earth?

A
  • CP receives document and completes the work
  • CP enters substation DrESS scheme applied to down droppers in clearance section of safety document
  • SAP informs CPS that the DrESS scheme is suitably rated to be converted to a primary earth
  • CPS puts the earth up on his screen and it remains there visible to the TNCC
  • This can now be quoted on OHL safety documents
57
Q

For isolation which is GIS what must you do ?

A

To be authorised as an SAP 1 on HV equipment and to sections 1-4, 8-10 of NSI 4 under NSI 30.

66
Q

Why do we have safety documents?

A

Working towards legislation recommendations, To provide safe access to the system, LAC will show boundaries to be maintained and highlights a safe working zone, PFW ensures that the safety precautions at the substation ends are secured and locked away so they cannot be altered until the work is complete, it also instructs the PIC to apply earths as per their earthing schedule for approaching the conductors.

67
Q

Take me through the setting to work process?

A

(To long to state here but have a robust description for how you set staff to work and why you go through certain things such as the tech data sheet and substation drawings!)

A

Retained for 3 years for audit purposes together with WPR, ES and RAMS

A

3

70
Q

Can you repair a damaged terminal tower Earth tape connection? How can it be done and what is the process?

A

No need NSI 24 authorisation, contact omega red for a quote, arrange access to substation via the relevant substation TL, who will arrange a substation SAP NSI 24 to give access to the earth tape.
