- Planned work details are interpreted from outage request or equivalent and stated on the draft program
- Where appropriate, the teams and individuals roles and responsibilities within the team are identified and, where required, assist in the provision of the on-the-job training
- Research switching programme
- Implications of switching program on the system are identified and recognised
- Types and function of switchgear to be operated are identified and their suitability for operation under forecast system conditions during scheduled outage is assessed
- System loadings, limitations and alternate supply route capabilities are evaluated to ensure system integrity
- Consultation with appropriate parties affected by the switching programme is undertaken in accordance with enterprise procedures
- Consideration is given to geographical and/or site location of isolation points to conclude shortest possible route when determining sequence of switching steps in order to minimise outage time
- Isolated work area is appraised to ensure safe working clearances are maintained in accordance with mandatory regulations and enterprise/site requirements
- H.V./L.V. and control circuitry is examined to ensure no back-feed to work is possible
- Draft switching program
- Draft is formatted in logical sequential steps, stating location, apparatus, apparatus ID and operation to be conducted
- Permit to work procedures are entered at correct step in program
- Program is planned to ensure access, work and reinstatement take place in a logical and sequential manner
