微机消谐装置(全称:微机电力谐振诊断消除装置)是放在放在PT的二次侧(所以也叫二次消谐)消除铁磁谐振的仪器。它与一次消谐器的区别在于微机消谐是一个消谐仪器，具有分析、记录、打印、上传等优势，但也有只能用于室内、消谐范围窄(只能消除工频、三倍频、二分频、三分频等指定频率谐振)等缺点。
Microcomputer harmonic elimination device (full name: Microcomputer power resonance diagnosis and elimination device) is placed on the secondary side of PT (so also called secondary harmonic elimination) to eliminate ferroresonance instrument. It differs from the primary harmonic eliminator in that it is a bingxisuan.07858.netmojusl.37ix.com.cnmojuldlc.37ix.com.cnpprkeli.71ix.com weixinghulu.07858.netzaozhi.07858.netharmonic eliminator with the advantages of analysis, recording, printing and uploading, but it also has some shortcomings such as being only used indoors and having a narrow range of harmonic elimination (only eliminating specified frequency resonances such as power frequency, triple frequency, bisection frequency and triple frequency).
市场上的微机消谐型号大都是厂家自己命名，功能大致相同，没有统一的标准，所以消费者比较难以理解，除了参数外还有详细功能上一定要清楚。
In the market, most of the harmonic elimination models are named by the manufacturer itself. They have the same functions and no unified standard. Therefore, consumers are difficult to understand. Besides the parameters, the detailed functions must be clear.
