VRIOGS 010.3 Revision A 15i) As a guide only, existing layouts of traction power supply installation maybe perused. A concept layout drawing may be provided on request.8.2 EQUIPMENT REQUIREMENTSFor each item of electrical equipment it is imperative to obtain specific informationsuch as:• Performance characteristics - mechanical/noise.• Performance characteristics - electrical/protection requirements.• Physical size, mounting details.• Terminal connections - (heavy current, control wiring)• Recommended spares and their availability.• Maintenance requirements and procedures.• Environmental impacts and requirements.• Required clearance from other equipment.• Required clearance for maintenance and inspections.Where such information is not available from the System Design Data Sheets, thedesigner shall obtain the information from individual equipment manufacturer(s).The Substation equipment will be remotely operated by a SCADA system, withprovision for local operation of all equipment. The Remote Terminal Unit of theSCADA system will be provided and installed by the Department’s representative.The designer shall coordinate with the Department regarding the provisions to bemade in the building for SCADA equipment.The substation, complete with electrical equipment shall be designed for minimumwhole of life costs. To this end, characteristics such as efficiency availability,accessibility, maintainability, reliability and compatibility with the existing System arethe criteria used in the determination of minimum whole of life costs. Equipmentselected needs to be supportable for at least twenty five years after commissioningwith spare parts and technical support available.Equipment selected shall be proven in service in a railway environment wherepossible.As per AS 3439 each switchgear assembly shall be provided with one or morenameplates that are durable, visible and legible when the assembly is installed.The Designer is responsible for the identification and documentation of all training,training support, materials handling and tools, maintenance plan and maintenancemanuals which will be required by the Department's staff to effectively operate andmaintain the substation equipment throughout its economic life.The following substances are not to be used in any part of the traction power supplyinstallations:• Asbestos• Polychlorinated biphenyls (PCBs)• Sulphur Hexafluoride (SF6)In conjunction with the Substations System Design requirements the completedNOTE:This document is controlled only when viewed on the DOT Engineering Standards website.Any other copy of this document is uncontrolled, and the content may not be current.
