Based on Faraday effect, a bulk-glass passive OCT is developed by using phase compensation and sensing head assembly technique. 基于法拉第效应，利用相位补偿和传感头组装技术，研制了块状玻璃式无源光电电流互感器。
Analyze the rotor seat phase shifting which the filter brings to the circuit, proposes the phase compensation's method, carries on the confirmation through the experiment. 设计了过零检测电路，对电路中滤波所带来的转子位移相进行误差分析，提出相位补偿的方法，并通过实验进行了验证。
