放电试验

• In this circuit , we use many kinds of negative feedback to modify the ou tput wave , which can decrease the distortion . and we use the high - voltage and high frequency capacitance efficiency , which can decrease the disturbance of output signal of variable frequency source for the test of part discharge
  采用了多种负反馈回路修正输出波形，使得输出电压波形的失真度很小；并且在电路中有效利用高压高频电容，减小了变频电源输出的电压对局部放电试验时的干扰。
