4 Switchgear services Services for high- and medium-voltage equipment High- and medium-voltage switchgear are the core elements of every power network. Their fault-free operation is a prerequisite for a reliable power supply. Siemens equipment meets the highest requirements in terms of efficiency, safety, and reliability. We support our customers throughout the entire lifetime of their switchgear. Because valuable assets deserve excellent service! Siemens offers the full range of services for high- and medium-voltage switchgear, from planned maintenance and inspections, repair services and spare parts, and modernizations and extensions to audits and consulting. In addition to Siemens products, we also service Magrini Galileo, Merlin Gerin, Elin Holec, Reyrolle, and Allis Chalmers products. Planned maintenance and inspection Siemens services cover all required overhauls and condition assessments for fault-free switchgear operation. Maintenance serves to monitor your equipment and increase its wear-and-tear reserve, which maintains or even improves its reliability. Our services are predefined according to manufacturer recommendations, but can be flexibly adapted to individual requirements. We offer timeand condition-based maintenance. Time-based maintenance follows the OEM s recommended time schedule of regular service visits to ensure the reliable operation of your equipment. Condition-based maintenance is a process-driven measure that is triggered when a critical condition or deteriorating performance of an asset is indicated. Repair services and spare parts Repair measures aim to quickly return your equipment to a functional condition. One essential prerequisite for successful and fast fault recovery is, of course, the availability of the necessary spare parts. If a failure occurs, Siemens assists you by providing repair services on-site, emergency services including 24/7 availability and contractually determined reaction times, and an international network of spare-part suppliers, repair workshops, and service centers. 4

5 Modernization and extensions To keep up with the pace of technological development, modernizations and extensions are a costeffective choice. Offerings like retrofits (for HV and MV switchgear), bay extensions (with original or state-of-the-art technology), and switchgear modifications (upratings and upgrading of MV switchgear) maintain and even increase the performance of your switchgear. Siemens develops customized solutions that include design, testing, and installation. As one of the world s leading suppliers of switchgear technology, we offer the comprehensive product range and service for current as well as phasedout switchgear types. Your benefits Comprehensive service throughout the entire lifetime of your switchgear from a single souce Expert services based on OEM expertise and decades of experience worldwide Short reaction times in the event of an emergency Reliable asset operation and potential increase in asset performance Audits and consulting Siemens has a strong legacy of expertise that extends across all transmission and distribution equipment. Our standardized audit tools deliver objective and comparable condition assessments. In addition to regular inspections during maintenance services, Siemens offers extended diagnostics and condition assessments to enhance asset management and maintenance strategies. Standard audits is a standardized approach that includes information gathering, visual inspections, and extended diagnostics. The results are displayed in user-friendly and well-structured reports that can be used immediately by asset management decision makers. Offline condition assessments focus on in-depth equipment checkups, including analysis, measurements, functional tests, and electrical and mechanical health checks. Certified service engineers record failures on-site and provide recommendations for the necessary measures. 5

6 Transformer services Reliable condition assessments and continuous monitoring as well as maintenance and repair reduce your transformer lifecycle costs. At the same time, your assets are kept in good condition and can be operated at nearly the maximum utilization rate. Siemens transformer services include the following: Condition assessment and diagnostics, online monitoring Consulting, expertise, and training Maintenance and lifecycle extension Spare parts and accessories Repair and retrofit Transport, installation, and commissioning Transformer service programs. Condition assessment and diagnostics This makes it possible to precisely detect the transformer s current condition and classify its operational reliability for all makes and models and all voltage and power levels. Especially after extraordinary events like thunderstorms and lightning, relocations, and similar occurrences, comprehensive testing including on-site high-voltage testing is recommended. Online monitoring is available at three levels, from component monitoring to monitoring of individual transformers to comprehensive fleet monitoring. Consulting, expertise, and training This service provides you with solid consulting on repairing or replacing your transformers and investing to maintain their value regardless of their age or manufacturer. On the basis of a detailed survey, we prepare an action plan with recommendations, if applicable, for each transformer depending on its individual condition and operational importance. Siemens also offers a series of standardized customer trainings. These programs are specifically designed to broaden our customers awareness of our diverse concept and design options. Lifecycle management is, of course, an integral part of the training. Maintenance and lifecycle extension These services minimize the unavoidable, undetectable, and ongoing aging processes taking place inside your transformers. Our stationary and continuous oil drying system as well as the regeneration of the oil filling completes our offerings for improving cooling efficiency with intelligent devices and hermetic sealing which can easily be integrated as retrofit solutions. Spare parts and accessories We recommend the critical spare parts you need to meet your specific requirements. In the process, we will evaluate different product alternatives and provide advice on up-todate replacement solutions. This is especially important if the original equipment manufacturers are no longer in existence. Repairs and retrofit Siemens offers complete repair as good as new and modification of power transformers of any brand and any age. On-site repairs can be nearly as good as in-house factory repairs. Mobile workshops require considerable setup, but the expense is usually outweighed by the excessive downtime and transport costs that would otherwise be absorbed by system operators. 6

7 Cable services The backbone of the electric power supply consists of high- and medium-voltage cable systems. Siemens comprehensive services for cables include the design and project planning of high-voltage cable systems, cable assessments, and fault location. Design and project planning of high-voltage cable systems System engineering and design Electrical design, arrangement, and cable bedding Assembly, EMC, grounding, and hydraulics Calculation of pulling forces, clarification of functional interfaces Technical procurement Time and resource scheduling, scheduling of monitoring Supervision of civil works, cable laying, and certified professional assembly of cable terminations and joints Installation and commissioning Maintenance and measurements Fault location (for example, using LIRA technology), refurbishment (for example, with cable life extension) Retrofit, modernization, modification, design, and extension Monitoring (temperature, partial discharge) Dismantling of existing installations Siemens services for high-voltage cable systems up to 500 kv extend from the engineering of cable dimensions to the final test after installation. We service cables with synthetic insulation (for example, XLPE) of various designs (up to 500 kv), low-pressure oil-filled cables (up to 400 kv), and gas-pressure cables (up to 110 kv). Backed by over 150 years of experience, our excellent overview of the entire market allows us to offer you vendor-neutral advice and support for entire systems and accessories. We employ technologies and high-grade materials matched to your needs in all work activities, from cable-laying tools to the professional assembly of fittings with cable-sealing ends and joints. We can assist you whether you plan to retrofit, convert, or extend your system. If you intend to dismantle an existing installation, we can manage the disposal or recycling of cables and cable fittings. Conducting all our work activities in accordance with national and international regulations and guidelines is mandatory for Siemens. 8

8 Cable assessments and fault location Knowing the condition of your assets reduces the risk of unexpected downtimes. Water trees (humidity infiltrated into the insulation), aging, harsh environments, and mechanical stress can all cause severe damage. Cable assessments precisely locate areas of degradation and enable us to initiate corrective actions before a cable fails. On the other hand, if a failure occurs, precise fault location enables us to undertake corrective measures immediately, which minimizes recovery time and extra costs. Siemens uses approved detection methods for installed high- and medium-voltage cables, namely partial discharge (PD) diagnostics, dissipation factor (tan δ) measurement, and frequency domain reflectometry (FDR). The FDR method is based on line resonance analysis (LIRA) developed by Wirescan. Your benefits Comprehensive services throughout the cable s entire lifetime from a single source Vendor-neutral advice from experienced service engineers Reliable operation and enhanced asset performance Our long-standing experience in developing complex engineering solutions 9

9 TLM repairs take into account environmental factors by offering modern replacement winding sets that are designed and manufactured with the latest technologies and solid insulation materials. These greatly reduce environmental risks (for example, replacing asbestos gaskets). Repairs and retrofits should follow a comprehensive and detailed master plan for any age, brand, and type of power transformer, based on a thorough condition analysis and fleet assessment. Depending on the evaluation s outcome, our experts create a plan for preventive, remedial, and/or corrective actions and any needed replacements. Transport, installation, and commissioning Siemens specialists have decades of experience in installing and starting up new units and relocating transformers that are already in service. Our individual solutions include disassembly to prepare for transport, packaging of sensitive components, shipment, reassembly, installation and commissioning, and preparation for energizing. Transformer service programs These programs are an umbrella that covers the entire transformer services portfolio. A precise match with the system operator s requirements can be achieved in several areas: single assets to entire networks, preventive maintenance to remote services, and short-term contracts to long-term agreements. Your benefits Maximum availability Reduced environmental impact Extended service life Fewer downtimes Minimal service interruptions Targeted control of expenditures 7
