|
Coating for telecommunication cables |
||||||
|
customers demand |
||||||
|
To coat fibre optics cables, a direct current voltage of 14,5 kVDC and a current of 2Amp. should be available. The rest ripples should be as small as possible and the transformer voltage stiff. |
||||||
|
solution |
||||||
|
By using the vector group Dd0y5 at the transformer, a 12 pulse rectification can generate a stable DC voltage. With a good linking between primary and secondary we can reach a small short circuit voltage Uk. For a voltage regulation, the primary winding gets 5 tappings. |
