摘要
介绍了使用CS5460A进行三相电能表应用设计方案,重点讨论了设计方案中需要注意的几个特殊技术问题,如:增益校准、角差校准、无功功率计算及其极性判别等。采用这种方案,已形成产品,并通过中国电科院形式试验,误差数据也很好。
A solution to three-phase meter design base on CS5460A chips was introduced,and some special technica were discussed,such as gain-cal,phase-cal,algorithm of reactive power and its polarity discrimination.The product has been developed through this method.And the product has passed the type testing by China EPRI,the error data is also good.
