The coreless PCB transformer concept has not received much attention,probably because there are misunderstandings: that planar winding with a few turns printed on a PCB is almost like a 'short-circuit' and that magnetic core is an essential component in transformer construction.

无铁心印制电路板变压器的概念没有受到人们很多关注，多半是因为存在误解：（i平面绕组在印制电路板上只能印制几匝，差不多像是&短路线&；在变压器结构中，磁心是根本的元件。

For example, by the rules of IEC and Chinese national standard, when the variety of the short-circuit reactance of a homocentric winding exceeds 2%, a certain extent of deformation can be affirmed.

例如，IEC和我国国家标准规定，对于同心式绕组，如果短路电抗变化量超过2％，即认为绕组有明显的变形。

When a whole winding is not used temporarily, the terminals must be short-circuited.

The in-depth analyses and simulation calculations of two simplification methods are carried out in this paper. Then it is pointed out that the equivalent d- and q-axes damper winding model is not suitable for calculating the internal short circuits because the concept is not applicable in this situation, and the errors caused by it are too obvious to be accepted in electrical engineering; while the approximate damper cage model is acceptable since it not only meets the accuracy requirement of electrical engineering but also saves calculating time for computers.

本文对阻尼回路的2种简化方法进行了深入分析和仿真计算，指出等效d轴和q轴阻尼绕组模型应用于电机内部短路计算时，物理概念上存在缺陷，且会造成过大的误差、在工程上无法容许；而近似阻尼笼的处理方法既能满足工程精度要求，又可节省计算时间。

Moreover, second-winding current waveform of a current transformer is calculated under the transient current of the typical short-circuit fault by numerical method. The analysis shows that the relevant protection equipment may refuse to trip when the fault current is extra high. It will result in the maloperation of protective relays for loss of their selectivity, and cause other protective relays to operate beyond range, and extend the scope of shutdown of power supply.

在这些回路出口处发生相间直接短路等严重故障时，流过相应TA一次侧的故障电流可能达到TA额定工作电流的100倍以上，大大超过了保护用TA的10%误差容许倍数，将使TA严重饱和，从而影响相关的保护设备的动作性能，因此有必要对在这种特大电流作用下的TA的传变特性做一些探讨，以分析其对继电保护装置动作特性的影响及应采取的措施。
