| Abstract: | This paper introduces a design scheme of the feeder switchgear protector based on CPLD, which can judge malfunction if the system has current leakage, open-phase and the load imbalance questions accurately by detecting phased. The data collection system can drive the A/D converter stable and reliable by CPLD, which is rich in internal resources and has high speed processing function. The practice shows that the method can save cost by improve the system resource and also can shorten period of development. The protector has simple circuit and easy to transform. |
