摘要
论述了一种复合型小电流传感器具有介损因数测量和局放信号测量双重功能。分析了传感器的基本原理、频率特性和各种影响因素。通过测试和模拟试验，证明这种传感器能够满足双重测量的技术要求。
The paper presents a new type of mini-current sensor, which is useful either for dielectric lose factor (tgδ) measurement or partial discharge (PD) measurement. The paper consists of principle, frequency characteristics and influence factors of the sensor, etc. With the checking and simulating tests, it has been proved that the sensor is satisfied for both measurements of tgδ and PD.
