An arrangement for supplying consumers in a rail vehicle with electrical energy, particularly consumers in a rail vehicle or train unit driven by a diesel electric drive unit, in which the arrangement comprises: - a generator for generating the electrical energy, with the generator preferably driven by a diesel engine, - a direct current link connected with the generator, - a consumer inverter for generating alternating voltage from the direct current link, - an alternating current consumer connection which for transferring electrical energy connects the consumer inverter with one or several consumer connection points for connecting one or several of the consumers, characterized in that - the electrical line of the alternating current consumer connection connects the inverter without galvanic isolation with the consumer connection point or consumer connection points, - the generator is a synchronous machine and the arrangement is designed to operate the generator overexcitedly at low speed when the rail vehicle does not require drive power, - the alternating current consumer connection and/or an electrical connection between the consumer connection point and the consumer comprises a low-pass filter (LZSS, CZSS) with an inductance (LZSS) and a capacitance (CZSS), and - the inductance is divided into several parts (L1ZSS, L2ZSS) with one of the parts (L1ZSS, L2ZSS) each disposed in one of several lines (46, 47) of the alternating current consumer connection or the connection between the consumer connection point and the consumer. - a generator for generating the electrical energy, with the generator preferably driven by a diesel engine, - a direct current link connected with the generator, - a consumer inverter for generating alternating voltage from the direct current link, - an alternating current consumer connection which for transferring electrical energy connects the consumer inverter with one or several consumer connection points for connecting one or several of the consumers, characterized in that - the electrical line of the alternating current consumer connection connects the inverter without galvanic isolation with the consumer connection point or consumer connection points, - the generator is a synchronous machine and the arrangement is designed to operate the generator overexcitedly at low speed when the rail vehicle does not require drive power, - the alternating current consumer connection and/or an electrical connection between the consumer connection point and the consumer comprises a low-pass filter (LZSS, CZSS) with an inductance (LZSS) and a capacitance (CZSS), and - the inductance is divided into several parts (L1ZSS, L2ZSS) with one of the parts (L1ZSS, L2ZSS) each disposed in one of several lines (46, 47) of the alternating current consumer connection or the connection between the consumer connection point and the consumer. - the electrical line of the alternating current consumer connection connects the inverter without galvanic isolation with the consumer connection point or consumer connection points, - the generator is a synchronous machine and the arrangement is designed to operate the generator overexcitedly at low speed when the rail vehicle does not require drive power, - the alternating current consumer connection and/or an electrical connection between the consumer connection point and the consumer comprises a low-pass filter (LZSS, CZSS) with an inductance (LZSS) and a capacitance (CZSS), and - the inductance is divided into several parts (L1ZSS, L2ZSS) with one of the parts (L1ZSS, L2ZSS) each disposed in one of several lines (46, 47) of the alternating current consumer connection or the connection between the consumer connection point and the consumer.
