These voltage differences are caused by the flow of current through the running rails back to the substations. Rectifier group Achieve maximum cost-effectiveness A secure power supply for your contact lines: The main technical changes with regard to the previous edition are the restructuring of all clauses and changes in the touch voltages limits. Europe ; United States Subject Areas: 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.
American Society of Mechanical Engineers. Rail Automation Optimum, systematic route efficiency. Rail Services Rail systems must do one thing above all: Sitras REC type rectifiers are designed to supply traction power to DC-operated mass transit systems and main-line railways.
Rectifier transformers for the DC traction supply system 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 special demands of these rail services are met by air-cooled disc-type diodes with a high blocking voltage. Stell, R W Benjamin Conference: Sitras REC diode rectifiers Download brochure.
The system and its components.
IEC 62128-1 Ed. 2.0 b(2013)
Voltage-limiting equipment that can be installed in passenger stations and other accessible locations has been developed in response to the jec of EN Distribute energy feeds efficiently and connect them reliably with the rectifier group, regardless of whether you select a gas- or air-insulated indoor installation.
It is important to us that you purchase the right document.
Benefit from our decades of experience in the engineering, construction, isc commissioning of DC traction power supply systems. 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.
Follow these links to find other Standards similar to the one you are viewing. The lack of an intentional connection between the tracks and earth allows voltage differences to occur along the rails, and between the rails and nearby structures. Sitras LCU can be placed at stations or stops or can be integrated into traction substations. Sitras SCD-C compact short-circuiting device for DC traction power supply In DC traction systems, impermissible contact voltage can occur between the return circuit and the structure ground due to operational currents and short-circuit currents.

Each track tie and insulated rail fastener assembly can be electrically represented as a resistor lec high ohmic value connected between the rails and the earth.
Turnkey Rail Solutions Integrated, reliable and sustainable rail systems. 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.
