Following the successful testing of the rectifier unit for traction power supply, uSky Transport has received official confirmation of the unit's compliance with key international safety standards. The inspection report from SWTUV Certifications documents full technical conformity of the equipment with requirements for installation quality, functionality, and electrical safety.

uSky Transport - Reliability confirmed: final inspection report by SWTUV Certifications
Reliability confirmed: final inspection report by SWTUV Certifications

Key findings from the testing:

 

  1. Visual and Functional inspection:

 

  • All control panels, warning signs, and protective components (isolators, busbar guards, cable insulation) were found in excellent condition.

 

  • Protective Earth (PE) connections, insulation resistance, and grounding systems comply with IEC standards (IEC 62109-1, IEC 60364).

 

  • Tests of indicators, alarms, cooling fans, and control buttons confirmed their operational functionality.

 

  1. Verification of technical specifications confirmed compliance with the following parameters:

 

  • Input/output voltage.

 

  • Grounding: All PE conductor resistance values were significantly below the 0.05 Ω threshold.

 

  • Short-circuit current tests: Earth fault currents (PEFCk) remained within safe limits, and short-circuit currents (PSClk) matched design calculations.

 

  1. Safety systems:

 

  • The IT system's earth leakage tripping device functioned correctly, activating alarms upon insulation fault detection.

 

  • High-voltage tests revealed no damage.

 

  1. Operational aspects:

 

  • Ambient temperature during testing reached 40°C but did not adversely affect system performance.

 

  • The cooling system was verified as fully operational, ensuring long-term reliability.

 

The inspection confirmed the rectifier unit's compliance with international safety standards, underscoring uSky Transport's commitment to advanced and reliable technologies. With no defects identified and all systems operating as intended, this achievement paves the way for the next phases of infrastructure deployment.

 

Stay tuned for updates as we progress toward sustainable and efficient transport solutions for the future!
