General requirements for safety – Collateral Standard: Emission and immunity of the signalling and telecommunications apparatus This part specifies limits for electromagnetic emission and immunity for signalling and telecommunications apparatus installed within a Railway.

Emission and immunity of the signalling and telecommunications apparatus. Click to learn more. Revisions British Standards are updated by amendment or revision. Such locomotives also contain auxiliary systems which 50112-1 be sources. Moreover, the high level of service quality proven by BELAC accreditation in this field makes our laboratories especially attractive for this industry. In an electric railway, the trains have to be supplied via sliding contacts from a supply line, called the catenary or overhead, or a trackside conductor rail, which is installed along the track.

Emission of the whole railway system to the outside world Railway applications – Electromagnetic compatibility 500121-1 No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer, when the apparatus is used as intended. The Electronic Components EMC department of the ANPI laboratories conducts tests on components installed on trains and along the tracks, in accordance with the following standards.

Auxiliary power is also regulated and, although of lower power than that supplied to the electric traction motors, can still be a significant source of electromagnetic noise.

This collection is via a series of short arcs which act as radio sources; special case arcing and transients which are produced when the pantograph is raised or lowered, or the vehicle circuit breaker is closed or opened.

Home Laboratory tests Railway electronics Railway electronics. The latter must be compatible with the emission limits set for the railway as a whole and also provides for establishing confidence in equipment being Fit For Purpose in the Railway environment. Other requirements and other EC Directives may be applicable to e products falling within the scope of this standard.

Rolling stock – Train and complete vehicle This part specifies the emission and immunity requirements for all types of rolling stock.

The compatibility between railway emissions and their external environment is based upon emission limits from the railways being set by considering the results from measurements at the time that the EMC Directive became enforceable. Radio frequency radiated waves. Railway applications – Electromagnetic compatibility – Part 1: International Classification for Standards ICS is an international classification system for technical standards.

Your basket is empty. Isolated three phase lines exist with two overhead een. Railway applications – Electromagnetic compatibility Part 2: This auxiliary current may return to the locomotive via the rails and 5012-11 have an influence on apparatus on the track. The market for on-board electrical equipment on trains and for signalling equipment installed alongside the tracks is especially demanding because of: It is produced transiently at substations when high voltage switching takes place, is distributed along the overhead when it is energised, is enhanced when non-linear traction loads such as rectifiers are supplied, and is stimulated locally when flashover takes place.

It consists of five parts described at the end of this introduction. Follow these links to find other Standards similar 550121-1 the one you are viewing.

Rolling stock – Train and complete vehicle Railway applications – Electromagnetic compatibility Part The limits for EMC phenomena are set so that the railway as a whole satisfies the Directive on electromagnetic compatibility with the outside world, and so that EMC is achieved between the various parts of the railway. Phenomena excluded from the set are Nuclear EM pulse, abnormal operating conditions and the induction effects of direct lightning strike.

It is incorporated by Royal Charter. The railway apparatus is assembled into large systems and installations, such as trains and signalling control centres. On low voltage lines, a trackside conductor rail may be provided from which power is collected by a sliding contact known as ej collector shoe.

BS EN Among the phenomena which are involved in RF emission are: You may find similar items within these categories by selecting from the choices below:. On the traction vehicle, the power is regulated and supplied to electric motors to control the movement of the train.

The biological effects of non-ionizing radiation as well as apparatus for medical assistance, such as pacemakers, are not considered here. The immunity and emission levels do not of themselves guarantee that the railway will have satisfactory compliance with its neighbours.
