發生匝間短路故障時，盡管短路匝電流很大，但流出一次側電流非常小。 傳統的保護措施是通過整定繼電保護的參數來實現的，這對一些尚不致于產生保護動作的匝間短路故障的診斷就無能為力。對于瓦斯繼電器，只有當氣體積累到某一較小容積時才能動作，故瓦斯保護反應干式變壓器內部這種匝間短路故障的速度慢、時間長。因此，如何在繼電保護動作之前及時地監測這種潛伏性故障，避免干式變壓器非正常退出運行就顯得非常必要。 對干式變壓器有功損耗物理機理的研究是新的干式變壓器匝間短路故障在線監測方法的基礎。電力干式變壓器的有功損耗分為負載損耗和空載損耗兩大部分，其中，負載損耗包括基本損耗（歐姆損耗）和由漏磁場引起的附加損耗（雜散損耗）；空載損耗（鐵心損耗）包括基本損耗（渦流損耗和磁滯損耗）和由漏磁場引起的附加損耗。 空載損耗包括基本損耗和附加損耗兩部分，前者包括磁滯損耗和渦流損耗，后者主要是由漏 磁場在干式變壓器內部產生的各種附加損耗。干式變壓器匝間短路后，一方面，由于短路匝中電流很大，造成鐵心局部嚴重飽和，導致損耗增加；另一方面，由漏磁場的變化將直接影響到附加損耗的變化原理可知，繞組如果發生了匝間短路故障，將直接影響到漏磁場在干式變壓器內部的分布，從而直接影響干式變壓器內部附加功率損耗的大小。干式變壓器繞組發生匝間短路后，故障相所引起的漏磁場變化很強烈，非故障相的不明顯，從而可得到結論：干式變壓器繞組發生匝間短路后，故障相的附加損耗就會發生比較大的變化，其他繞組的附加損耗也有變化，但是變化很小。總之，干式變壓器繞組發生匝間短路故障后，由其內部磁場的變化所引起的功率損耗將會增大。 正常運行時，干式變壓器的附加負載損耗是指干式變壓器線圈導線中的渦流損耗，線圈內部的環流損耗以及結構件中的渦流損耗，這些附加損耗都是負載電流引起的漏磁通所感應產生的。 當干式變壓器發生匝間短路時，會引起下列變化： ①由于短路使短路所在相繞組匝數減少了，短路后將產生一個短路電流，此短路電流使干式變壓器產生一個附加的損耗，同時，在短路的線匝之間形成一個短路環，短路環的電流較大，也產生了一個附加的功率損耗。被短路的繞組相當于一個匝數等于短路匝數的短路環加在干式變壓器的鐵芯上，該短路繞組內的電流近似等于干式變壓器的短路電流（環流），可以達額定電流的20倍以上（但干式變壓器繞組引出線上的電流變化并不大）。短路環流引起干式變壓器局部發熱，造成鐵心的局部飽和，也引起額外的功率損耗（與電流平方成正比），而且對于不同的匝間短路，此增加損耗不同，增加損耗隨著短路匝數的增加而增大。 ②對多臺干式變壓器并聯運行，若原方短路，則副方電壓將略有升高，若副方短路，則副方電 壓略有降低，這都會使并聯運行的干式變壓器之間產生環流，也將會使干式變壓器損耗增加。 ③從能量的觀點來分析，當干式變壓器發生匝間短路故障后，在故障點將形成一個放電點，隨 著弧光放電產生，必將消耗大量的功率損耗，其具體的數值將依賴于過渡電阻的大小。 綜上所述，可以得出結論：當干式變壓器繞組發生匝間短路，會使干式變壓器的負載鐵耗和空載損耗 均增加從而導致總損耗增加，而且對于匝間短路嚴重程度的不同，此增加損耗也不同，損耗會隨著短路匝數的增加而增大，具體的數值依賴于短路故障的嚴重程度以及過渡電阻大小等因素。
