Designing a 1500 V DC input filter for a tram’s auxiliary converter.

| Parameter | Normal Range | |-----------|----------------| | Ambient temperature | –25 °C to +40 °C (class T1) or –40 °C to +50 °C (special classes) | | Altitude | ≤1400 m above sea level | | Humidity | ≤95% (with possible condensation) | | Pollution degree | PD3 (heavy industrial/railway environment) per IEC 60664-1 | iec 60077-1

Julian looked back at his tablet. He adjusted the parameters in the simulation software. He changed the reference standard from "Industrial Stationary" to "Railway Traction - IEC 60077." Designing a 1500 V DC input filter for

: Power circuits, auxiliary supply, control systems, and batteries . It works in close conjunction with (insulation coordination)

IEC 60077-1 is a fundamental standard within the railway industry, forming part of the broader IEC 60077 series. It establishes the and general rules for electric equipment used on railway rolling stock (locomotives, EMUs, DMUs, tramways, and metro cars).

It works in close conjunction with (insulation coordination) and IEC 61373 (vibration & shock), but remains the primary reference for defining how electrical equipment should be specified, designed, and validated for rail vehicles.
