Our end-to-end modular portfolio of converters, DC switchgear, and protection systems lets you operate your rail systems with confidence — and with top performance, efficiency, and safety. The system and its components. It is important to us that you purchase the right document. We recommend that you check the website of the publishers of the international document before making a purchase.

Designed especially for highly dynamic rectifier loading, our rectifier transformers have power ratings that range from approximately one MVA for stations supplying trolley cars and trams to approximately seven MVA for operating heavy subways.

The formation of stray currents is also minimized by automatically opening the short-circuiting device. International Classification for Standards ICS is an international classification system for technical standards.

Protection 6128-1 on the safe side Proven protection for contact lines, future-proof and easy to operate: High-performance DC traction power supply: For modern dc traction power systems in particular, however, this resistance is high enough for the rails to be considered essentially ungrounded with respect to local electrical ground earth.

Sitras LCU can be placed at stations or stops or can be integrated into traction substations. Medium-voltage switchgear for the DC traction supply system For our DC substations, we use the same proven standard medium-voltage switchgear used by utilities and industrial plants. The purpose of this isolation is to prevent stray dc currents from flowing through the earth and potentially causing corrosion of nearby metallic infrastructure.

Modular portfolio DC traction power supply — high-performance, efficient, and safe Reduce costs and save resources using efficient, resilient traction power supply systems. Cost-effective operation reducing environmental impact, conserving resources — with reliable Rolling Stock. If an earth fault ic broken catenary conductor falling on the ground, for examplethere may not be a low-resistance circuit back to the substation due to the electrical isolation between running rails and earth ground.

Sitras LCU local charging unit Download brochure. American Society of Mechanical Engineers. Recharging occurs during dwell time by an overhead conductor rail. EN includes voltage-time curves that dictate the maximum permissible magnitudes and durations for ac and dc voltages; equipment built to EN must clamp the highest voltages in no more than 20 milliseconds.

DC traction power supply – Rail Electrification – Global

Reduce your voltage with transformers and use rectifiers to convert AC to DC current. Benefit from our decades of experience in the engineering, construction, and commissioning of DC traction power supply systems.

As a DC protection unit, it protects DC switchgear and contact line systems from critical operating conditions and detects short circuits during a current rise — even before maximum short-circuit currents are reached.

This standard applies to all new lines and to all major revisions to existing lines. A secure power supply for your contact lines: Voltage-limiting equipment that can be installed in passenger stations and other accessible locations has been developed in response to the requirements of EN Protective provisions against electric 6228-1 This document has been re-assessed by the committee, and judged to still be up to date.

It protects DC switchgear and contact line systems from critical operating conditions and detects short-circuits during a current rise — even before maximum short-circuit currents are reached. The maximum permissible voltage levels will be explained and compared. Sitras SCD-C reduces excessively high voltage by reliably short-circuiting the return circuit and structure ground temporarily.

Stell, R W Benjamin Conference: Although we endeavour to maintain an up-to-date catalogue, on occasion we may not have the latest version of a document, including where it has not yet been provided through an international feed. Traction power Geographic Terms: Rail Automation Optimum, systematic route efficiency. Contact Experience high performance — with the DC traction power supply Benefit from our decades of experience in the engineering, construction, and commissioning of DC traction power supply systems.

Turnkey Rail Solutions Integrated, reliable and sustainable rail systems. Each track tie and insulated rail fastener assembly can be electrically represented as a resistor of high ohmic value connected between the rails and the earth. Experience high performance An age of extreme urbanization calls for innovative and flexible mobility concepts. Standard oil-insulated or industry-proven cast-resin transformers are used that also fulfill special requirements for fire protection and safety.

For our DC substations, we use the same proven standard medium-voltage switchgear used by utilities and industrial plants. Medium-voltage switchgear Reliable operation Distribute energy feeds efficiently and connect them reliably with the rectifier group, regardless of whether you select a gas or air-insulated indoor installation. We provide all the services you need from a single source, creating valuable synergies in the process and giving you unique opportunities to save costs.

The prefabricated type-tested equipment with air or gas insulation complies with all national and international standards and guarantees the highest level of safety for operating personnel.
