Standard oil-insulated or industry-proven cast-resin transformers are used that also fulfill special requirements for fire protection and safety. Benefit from our decades of experience in engineering, construction, and commissioning of DC traction power supply systems.

Without a low-resistance path back to the substation, there may be a resulting low-level short circuit current flow insufficient to operate the substation protective systems. 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.

It is designed to cover every economic sector and virtually every activity of the humankind where technical standards may be 62128–1. We recommend that you check the website of the publishers of the international document before making a purchase. Modular portfolio DC traction power supply — high-performance, efficient, and safe Reduce costs and save resources using efficient, resilient traction power supply systems.

The Sitras REC-W is based on the service-proven series of 62128-11 diode rectifiers using air-cooled disc-type diodes with a high blocking voltage. 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 system and its components. Protective provisions against electric shock This document has been re-assessed by the committee, and judged to still be up to date.

These voltage differences are caused by the flow of current through the running rails back to the substations. Intermodal Solutions Intermodal Solutions comprise a range of innovative IT-based solutions that improve passenger comfort and travel. Reduce your voltage with transformers and use rectifiers to convert AC to DC current. Rail Services Rail systems must do one thing above all: 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.

Intermodal Solutions comprise a range of innovative IT-based solutions that improve passenger comfort and travel. Since the shells of rail vehicles are typically at the same voltage as the wheels and rails, this voltage difference could be impressed on a passenger entering or exiting iex train from a grounded platform.

As a DC protection unit, it protects DC switchgear and contact line systems from critical uec conditions and detects short circuits during a current rise — even before maximum short-circuit currents are reached. The formation of stray currents is also minimized by automatically opening the short-circuiting device.

Equipment intended to detect this condition and connect the substation negative dc bus to the substation grounding grid is gradually being incorporated into modern North American dc traction power substation design. The purpose of this isolation is to prevent stray dc currents from flowing through the earth and potentially causing corrosion of nearby metallic infrastructure.
