style="text-indent:25px">電子變壓器除了體積較小外，在電力變壓器與電子變壓器二者之間，并沒有明確的分界線。一般提供60Hz電力網(wǎng)絡之電源均非常龐大，它可能是涵蓋有半個洲地區(qū)那般大的容量。電子裝置的電力限制，通常受限于整流、放大，與系統(tǒng)其它組件的能力，其中有些部份屬放大電力者，但如與電力系統(tǒng)發(fā)電能力相比較，它仍然歸屬于小電力之范圍。各種電子裝備常用到變壓器，理由是：提供各種電壓階層確保系統(tǒng)正常操作;提供系統(tǒng)中以不同電位操作部份得以電氣隔離;對交流電流提供高阻抗，但對直流則提供低的阻抗;在不同的電位下，維持或修飾波形與頻率響應?！缸杩埂蛊渲兄豁椫匾拍?，亦即電子學特性之一，其乃預設一種設備，即當電路組件阻抗系從一階層改變到另外的一個階層時，其間即使用到一種設備-變壓器。</p><p style="text-indent:25px">變壓器短路干燥法：把變壓器的一側繞組短路，另一側用自耦變壓器施加電壓，使變壓器繞組內流過額定電流，依靠繞組銅損(I2R)產生的熱量來加熱變壓器，可達到干燥變壓器的目的，如圖32所示。本方法簡便實用，干燥升溫快。但需用自耦變壓器容量也較大，一般比燥變壓器的容量大10%以上。另外此法也容易產生局部過熱，并且耗電量較大，所以，一般只適用于燥變壓器容量不大的情況下。為了安全起見，一般都從變壓器低壓側施加電壓，而把高壓側短接。對三繞組變壓器，只能把其中一個繞組接電源，另一個短路接地，而第三個繞組要開路。使用短路干燥法應注意觀察短路側的電流不能超過該側的額定電流太多。變壓器耐壓試驗控制臺是由接觸式調壓器及其控制、保護、測量、信號電路組成。</p><div
