Powerformer is a new high voltage generator ， which use xlpe cable as stator winding instead of rectangular conductor bars ， thereby it overcome the shortcomings which the shape of these conductors results in an uneven electric field distribution with high electric field strenghs at the corners especially and prevents the output voltage of the conventional generator from exceeding about 36kv powerformer offers a direct connection to the network without the need for a step - up transformer as a consequence, there are some merits in the total plant equipped with powerformer, such as high effiency, high availability, low maintaining cost and giving less environmental impact
Powerformer是一種新型的高壓發電機，它採用電纜代替矩形導體作為定子繞組，從而克服了矩形導體電場分佈不均勻，特別是在矩形導體在導體拐角處電場過于集中而使常規發電機的輸出電壓等級不能高於36kv的缺點，使其能夠直接和輸配電網相聯，這樣就不需要升壓變壓器，同時也使裝配powerformer的電廠具有如下優點高效率、可利用率提高、維修費用降低和降低了對環境的負面影響。 -
