延伸阅读
电介质损耗电介质损耗dielectriclosses电介质中在交变电场作用下转换成热能的能量。这些热会使电介质升温并可能引起热击穿，因此，在电绝缘技术中，特别是当绝缘材料用于高电场强度或高频的场合，应尽量采用介质损耗因数（即电介质损耗角正切tgδ，它是电介质损耗与该电介质无功功率之比）较低的材料。但是，电介质损耗也可用作一种电加热手段，即利用高频电场（一般为0.3～300兆赫）对电介质损耗大的材料（如木材、纸、陶瓷等）进行加热。这种加热由于热量产生在介质内部，比外部加热的加热速度快、热效率高，且加热均匀。频率高于300兆赫时，达到微波波段，即为微波加热（家用微波炉即据此原理）。电介质损耗按其形成机理可分为弛豫损耗、共振损耗和电导损耗。前两者分别与电介质的弛豫极化和共振极化过程有关。对于弛豫损耗，当交变电场的频率ω＝1/τ时，介质损耗达到极大值，τ为组成电介质的极性分子和热离子的弛豫时间。对于共振损耗，当电场频率等于电介质振子固有频率（共振）时，损失能量最大。电导损耗则是由贯穿电介质的电导电流引起，属焦耳损耗，与电场频率无关。
