Elements and Performance Criteria
- Inspect and service line and cable routes
- Routes are inspected and recorded and arrangements are made for the removal of any obstructions, damage, infringing vegetation to provide free access to cables/aerials
- Routes are physically inspected to determine any breaks, misalignments, damage and insulation wear requiring repair
- Poles are inspected for deterioration and a safety assessment is made
- Diagnose line and cable faults
- Permission to test isolated equipment is confirmed prior to any work being undertaken
- Probable location of fault is identified from visual inspection and circuit tests are conducted to isolate fault area
- The nature of the fault is identified from further tests and corrective action required is identified to enable appropriate arrangements for resources and for work to be performed
- Disconnection/insulation procedures are applied to enable maintenance work to be carried out in isolation to systems where lines are in close proximity to high voltage services
- Repair line and cable faults
- Work site is made safe in accordance with organisations safety requirements to enable repair work to be safely undertaken
- Aerial lines/cables are repaired to operational and technical requirements using appropriate jointing or replacement/repair procedures
- Repaired/replaced line/cable is tested to specified standards to ensure conformity to operational and technical requirements
- Appropriate personnel are notified of completed repairs/replacement and appropriate documentation is completed in accordance with organisations requirements and returned to appropriate organisation/department as required
