1 European Railway Agency Electromagnetic Compatibility Requirements Denmark Extract of the study on EMC Requirements Lloyd s Register - November 2010

2 1. Processes Compatibility demonstration in Denmark is controlled by the National Rail Authority (Trafikstyrelsen) however, Banedanmark performs the compatibility process on its behalf. The regulation that controls acceptance BJ-1-5_2009 DTR is available on the web in Danish: A flowchart for the general approvals process is available in English on Approval is in three sequential stages; application for a operating licence, obtaining a safety certificate and type approval. All applications require an certificate of conformity from Banedanmark. Technical requirements for general rolling stock acceptance is to the requirements of the Banedanmark drawing QN 903 Q no 0779 with the technical rules concerning EMC related issues contained in BN A summary of the main points of BN2-74-1; BN is available in English on This document references various other standards including UIC and EN. General compatibility is by testing and performing calculations and simulations which are assessed by expert opinion. In the case of EMC, this is performed by the EMC system manager of Banedanmark (Figure 1).

3 2. Train Detection Compatibility with train detection is provided from test information from the train manufacturer. This is assessed by Banedanmark who provide assessment and certification. The manufacturer provides the results of the measurements and simulations and calculations based on the tests. Evaluation is based on the Banedanmark specification for the declaration of conformity QN 903 Q no 0779 and EN EN50238 is available from normal EN standards websites or from Banedanmark directly. Results are reviewed by Banedanmark to limits within these standards. The Danish system incorporates two types of ATC. Compatibility with the system ATC ZUB 123 is one of the requirements. For the HKT system and track circuits a summary of the conditions is shown in Figure 2. Track Circuit DC 77Hz centre frequency - 77Hz, 170Hz, 231Hz FTGS , 5.25,5.7 5,6.25 khz FTGS kHz in 1kHz steps 100kHz 100kHz HKT ( ATC) Interharmonics Hz* Bandwidth 0-2.5Hz 70-85Hz 300Hz 500Hz +/- 40kHz +/- 5Hz Analysis time Interference limit <4A continuo us <15A after 1.5 s inrush time <4A 2A 4A Freq Freq Domain A 0.7A 0.028A 1A Time >1.5 s >1s * Interharmonics are summations over the frequencies between 50Hz harmonics with a 5Hz exclusion e.g Hz for the 350 to 400Hz frequency range. Limits at the 50Hz harmonics are shown in Figure Figure 2 Track Circuit Frequencies Evaluation is carried out at all stages of the process and these leads to a declaration of conformity at the end of the testing. The process is stated to take from 2 to 3 months and the costs (excluding the manufacturers costs for testing) are approximately Lineside Systems Compatibility with Lineside systems is provided from test information from the train manufacturer. This is assessed by Banedanmark who provide assessment and certification. The manufacturer provides the results of the measurements and simulations and calculations based on tests. Evaluation is based on limits within the Banedanmark specification QN 903 Q no 0779 and EN Simulations and calculations are to be performed by the manufacturer to the requirements of EN Hence, it is implied that compatibility is assured by demonstration of compatibility with the power supply maxima (see section 4) as in many other countries. In addition, general broadband limits on currents for interference to information systems are given over broad bands up to 5kHz. 3

4 Compatibility with voice telecommunications is by calculation of psophometric current to CCITT (ITU) standards. Psophometric currents are defined for the train alone in normal - 2.1A >2s, 3.5A<2s and degraded modes:- 3.5 <2s, 5.7 >2s and for the general lineside environment (5.7A). Results are reviewed by Banedanmark who issue a certificate of conformance. The conformance demonstration is a single process. No timescales or costs are available 4. Energy Supply Compatibility with the energy supply is provided by the train manufacturer and Banedanmark. The manufacturer provides the results of the measurements and simulations to the requirements of EN50163, EN50388 and CCITT Directives. In addition, there are a series of permissible harmonic current levels at multiples of the supply frequency. These are shown in Figure 3. Frequency Permissible Current fundamental 50Hz 100Hz 500 A 25 A 150 Hz 50 A 200 Hz 12 A 250 Hz 50 A * Hz 10 A * cumulative harmonic levels for 50Hz multiples in range (see Figure ) Figure 3 Harmonic Current Limits The EN and CCITT standards are available in various languages throughout the member states. Evaluation is by comparison with limits within these standards and those in Figure and it is reported by issuing a conformance certificate. 5. Radio Frequency Systems Compatibility with radio frequency systems is assessed by the manufacturer. Compatibility is demonstrated by measurement to the requirements of EN and EN Testing is carried out by the manufacturer who issues a certificate of conformance. Denmark uses UIC Radio Chapter for ground to train radio (UIC code 751-3). Details of this system may found in the TSI CCS Annexe B. 6. Other Systems Denmark does not include assessment for compatibility with human exposure to EMF radiation in its rolling stock evaluation. Denmark does not include assessment for compatibility with the EMC directive in its rolling stock evaluation. 4
