Principle and its Application of Sampling AC Voltage and Current Synchronously

Dong Jianyou Li Jing An Rucun (Dept. of Electronics and Infor. Engineering, Hebei University, Baoding 071002)  
In the system of using computer to measure the parameters of three-phase alternating current network, we can caculate the effective value ofvoltage and current, active power and reactive power,etc, by sampling the AC voltage and current synchronously. So the traditional transducers are threw away. It brings simpler and more reliable system, more convenient safeguard and higher precision. In a word, it provides a simpler method for the SCADA system.
