摘　　要：一种 10 k V新型电压互感器 ,通过选用新型优质材料和优化设计 ,实现了精度 0 .2级 ,额定容量 2 0 0 VA的要求。可解决 10 k V电网电压互感器过载产生的计量误差问题 ,起到减少电能损失 。A new kind of potential transformer with high precision and large capacity is introduced in this paper. The voltage level is 10kV, the precision is 0 2 and the rated capacity could reach 200VA. Using the potential transformer in practice, the problem of measurement error in 10 kV power network which was caused by overload of the PT could be solved fundamentally, at the same time it can reduc the electric energy losses and raise the economic effect of electric enterprise.
