· IEC/EN 61558-2-13 / EN 60076-11
· Voltage adjustment
· Ambient temperature –25 to 40 °C
· Connection terminal (<=115 A)
· Frequency 50/60 Hz
· Vector group Yna0
· Maximum load to neutral point: 10% of nominal current
· Protective enclosure IP23
· Additional tapping
· Temperature monitoringg
· auxiliary winding
· required throughput rating 220 kVA
· required rated input voltage 690V
· required output voltage 400V
Notes for selection:
· ST = SN x (1 – Lowervoltage / Highervoltage)= 220 kVA (1 – 400V/690 V) = 92,5 kVA
· ST = type power = power, which is relevant for the size of the transformers
· SN = nominal power = power, which is the relevant figure of the load of the transformers
The type rated power is always smaller than the throughtput rating.
Versions with delta stabilizing winding on request.
The correct type designation reads DTFSP100(690/400).
The unambiguous article number of your configuration will be defined by trafomodern during the offer- and order process.
Technical notes
Important notes:
For versions with increased climate resistance, the transformer is supplied with a specially insulated finish. The finish allows the transformer to be used in areas of high humidity.
- CUR according to EIS 130 or EIS 155 to OBJY2. or OBJY8.E160829 (Systems, Electrical Insulation – Component bzw. Systems, Electrical Insulation Certified for Canada – Component)
When ordering, the following information must be added to the type designation:DTFSP100(*/*)
- 1st place holder ≙ rated input voltage
- 2nd place holder ≙ rated output voltage
