1、Voltage transformers are generally designed for a capacity of about 200voltamp.There are two causes of errors in voltage transformers,namely,ratio error and phase-angle error.The part of these errors due to the exciting courrent is constant for any particular voltage.It can be reduced to a minimum by choosing the best quality of iron and working it at a low magnetic density.The part of the errors due to the load current varies directly with the load and can be minimized by making the resistance of the windings very slow。
2、The secondary terminals of a voltage transformer should never be short-circuited,a heavy current will flow which,if continued,will burn out the windings.In order to protect the system against sustained short circuits in the transformer circuit it is generally recognized as good practice to introduce into the primary circuit a resistor and fuse,these being connected in series.The resistors are designed to limit the current to about 20 to 40 amp,while the fuses

变压器一般设计为约200伏安的容量。对于变压器而言有两种错误原因，它们是比率错误和相对角错误。 这些错误的部分原因是对任何特定的电压励磁来说电流都是一个常数，通过选择最好质量的铁或者在一个低磁密度下运作都能把错误降低到最小值。另一部分错误原因是由于负载电流会很快地随着负载的变化而变化，而使绕组电阻减缓同样可以使错误减到最低值。
变压器的次级终端是绝对不能短路的，强大的电流在短路的情况下将会持续供应，如果继续下去，就会烧坏绕组。为了保护变压器电路中的系统在持续的短路情况下完好无损，一般公认的好的做法是在系统内引入一组串联的电阻和保险丝。这些电阻的目的是限制20到40安培的电流，而保险丝是为了阻断这种电流。在正常运行情况下，电阻携带的电流只是非常小的变压器原电流，同时它们所造成的电压下降是微不足道的。
1、电压互感器是一种通常用于一个容量约200voltamp有两种:一种是引起的误差,即在电压互感器比值差和phase-angle错误这些错误的一部分是由于激动人心的courrent恒为任何特定的电压它可以减到最小挑选最佳品质的铁和工作以很低的磁性密度这个错误的一部分由于负载电流的变化和负载,直接在一定程度上可以减少的阻力,使绕组很慢。
2、二次接线端子的电压互感器不应该短路电流就重金属,如果继续下去,会烧坏了绕组为了保护系统持续在变压器电路短路,大家都公认为良好的练习,并将其引入主要电路电阻器及引爆,这些被连接在系列这个电阻是为了限制了大约20到40岁的电流安培,融合是为了打破这种电流当前,在正常运行的电阻携带只是很小的初级电流与电压互感器、高压,减少的原因是微不足道的。
