TRACTION DUTY

Traction transformers are critical components in the traction chain, affecting both train performance and operator service. MGM supplies traction substation transformers for all applications including high-speed, commuter and regional trains, and Light, Heavy, and Extra-Heavy duty.

MGM Traction transformers are offered as dry-type or liquid filled and can be located in either indoor our outdoor traction substations.  Compliant with IEEE 1653, our Traction units are built with overloads to allow for function at peak passenger loads with failed substations in the system. 

FEATURES

STANDARD FEATURES
  • Compliance with IEEE 1653.1-2017
  • Typically Traction transformers experience a high number of short circuits while in
    operations and transformers may be exposed to 10-20 times their rated current.
  • Traction- Typically the temperature rise is determined by the transformer overload
    rating defined in IEEE P1653.2. Overloads are chosen to allow trains to function at peak passenger loads with failed substations in the system.

1. Light Traction duty (150% for 2 hrs.)

• 100 % rated load cycle of the rectifier current in ampere continuously followed by either
• 150 % of rated load cycle of the rectifier current in ampere for 2 hours or
• 200% of rated load cycle of the rectifier current in ampere for 1 minute following 100% rated load

2. Heavy Traction duty (150% for 2hrs)

• 100% rated load cycle of the rectifier current in ampere continuously followed by either.
• 150% of rated load cycle of the rectifier current in ampere for 2 hours or
• 300% of rated load cycle of the rectifier current in ampere for 1 minute following 100% rated load

3. Extra-Heavy Traction duty (162 % rms for 2 hours)

• 100 % rated load cycle of the rectifier current in ampere continuously followed by

• 150% of rated load cycle of the rectifier current in ampere for 2 hours followed by
• 300% of rated load cycle of the rectifier current in ampere for 5 equally spaced periods, each 1 minute
• Followed by final 450% of rated load cycle of the rectifier current for 15 seconds.
