The article discusses issues of ensuring electromagnetic compatibility (EMC) of sensors for monitoring electrical power parameters and battery management systems with railway transport automation and telemechanics devices. The influence of high-frequency interference from inverters, switching processes and pulse sources on the stability of measuring systems is analysed. The parameters of LC filters, general-purpose chokes and precision shunts that ensure compliance with international EMC standards are calculated. Solutions are proposed for protecting DC circuits from impulse overvoltages and ensuring measurement reliability. The results confirm the possibility of improving the reliability of automation and telemechanics devices in complex electromagnetic environments.
