鉴于传统的电流互感器测试方法已经不适于校验新型的电流互感器，依据IEC标准和误差分析理论，提出了光电电流互感器的测试和校验方法。
Because the traditional calibrating method is not suitable for testing optical electric current transformer, a novel test system is designed based on the IEC standard and error analysis theory.
实验结果表明，由于光子计数器的核心器件光电倍增管及其高压电源不很稳定，光子计数器需要经常校验和标定。
Experimental results shows that the core device of the photon counter-PMT and it's high voltage power supply is not stable, the photon counter can be test and calibrated frequently.
