Role Summary: To carry out engineering designs in the secondary discipline for transmission and distribution projects and tenders in accordance with the project specifications, agreed timeframes. To validate the correct implementation of these designs by participation to factory and site installation / testing. Portfolio: “Medium-Set” complexity level projects with major portion on secondary engineering (e.g. GIS/MV substations)
Essential Responsibilities: 1.Secondary and Auxiliary System Design
1.1.Master project technical specifications and company standards and rules of secondary design
aspect.
1.2.Protection & Control scheme design: Produce highlevel scheme designs which are appropriate for the application. Including tripping, inter-tripping,
breaker failure, control and interlocking logics; protection communications; SCS/SCADA interfaces
and signal list.
1.3.P&C equipment: select / specify appropriate protection relays, controllers and meters
according to project
requirements. Perform sizing calculations to specify
appropriate CT and VT requirements.
1.4.Panel Schematic Design: design, specify and produce drawings and documentation detailing
protection and associated control circuitry, cubicle layouts/general arrangements, field cabling and
HV equipment interfaces.
1.5.Relay Settings and Configuration: Carry out system analysis as required for protection
coordination. Determine configuration/logic settings for relays in accordance with scheme and
circuitry designs. Produce reports detailing these settings and configuration.
1.6.Auxiliary System Design: design auxiliary AC/DC systems including load/sizing calculations,
protection, grading etc. Specify AC/DC distribution principles.
1.7.Cabling Systems: produce cable schedules and termination charts for control and small power
cables fed to panels; specify appropriate wiring systems.

budget.
2.4.Issue technical clearance and/or bill of quantities on schedule for secondary and auxiliary
systems equipment and/or accessories.
2.5.Inform promptly technical issues of secondary and
auxiliary systems that may affect project cost, time and quality. And request for resolution.
2.6.Inform promptly potential opportunities related to technical scope of secondary and auxiliary
systems.
2.7.Inform changes on secondary and auxiliary systems
that may impact other work packages.
3.Interface With Customer’s Technical Team
3.1.Establish good communication and working relationship with customer technical team in the
secondary and auxiliary system domain.
3.2.Attend technical meetings to resolve design issues in a
constructive manner.
3.3.Check customer comments are applicable according to project technical specifications and/or
relevant international standards.
3.4.Timely address customer’s comments.
4.Interface With Suppliers’ Technical Team
4.1.Review and liaise with secondary and auxiliary systems equipment suppliers to ensure
documents and
drawings comply with project requirements and/or
international standards.
4.2.Monitor suppliers’ documents quality. Populate supplier document quality records.
4.3.Attend technical meetings to resolve design issues, with project engineering manager and/or
project
manager when required.
5.Interface with Design Engineers / Managers
5.1.Timely update design manager on design progress and forecasted resource requirement.
5.2.Prepare return of experiences (ROE) on project/ customer for cross-fertilising the design team
of
secondary and auxiliary systems.
6.Environment
6.1.Adhere to all environmental procedures in accordance with instructions.
7.Health and Safety
7.1.Demonstrate commitment to safety through participation in formal and informal discussions,
regular
team visits and accident/ incident investigations where required
7.2.Participate in risk assessments on hazards identified
7.3.Adhere to all safe working procedures in accordance
