STANDARDISATION OF THE ELECTRIC EQUIPMENT OF PASSENGER COACHES. ENERGY SUPPLY SYSTEMS FOR AIR-CONDITIONED PASSENGER COACHES
The following report contains a theoretical comparison between the three-phase and direct current supply systems used on air-conditioned RIC passenger coaches. The comparison on a merely theoretical basis speaks in favour of the direct current supply system. However, certain line tests have shown that theoretical considerations alone are not sufficient to enable an unambiguous choice in favour of one of the two systems to be made. It is therefore recommended that more accurate tests should be carried out in the climatic chamber at Vienna Arsenal under equal environmental conditions with comparable passenger coaches, containing identical equipment and possessing the same features, and, above all, air-conditioning systems bringing the same refrigeration and heating output. Not until then could the study of the question of a standardized energy supply system be resumed. In conclusion, attention is drawn to the need for including the application of static converters in the future study programme.
