What are the percentage impedance guarantees of the Fast Trans range of Liquid Filled Distribution Transformers

The Fast Trans range of transformers, which are liquid filled free breathing distribution transformers, covers 8 kVA ratings and the percentage impedance guarantees varies for each rating as detailed below :-

315kVA           Percentage impedance guarantee = 4.75% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
500kVA           Percentage impedance guarantee = 4.75% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
800kVA           Percentage impedance guarantee = 4.75% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
1000kVA         Percentage impedance guarantee = 4.75% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
1250kVA         Percentage impedance guarantee = 5.0% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%
 
 
1500kVA         Percentage impedance guarantee = 5.5% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
1600kVA         Percentage impedance guarantee = 5.5% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%

 
2000kVA         Percentage impedance guarantee = 6.0% at a Reference Temperature of 75ºC, subject to IEC 60076 Tolerances of ±10%
