(EN) METHOD FOR PREPARING HIGH-ACCURACY DUAL-STAGE CLAMP-SHAPED CURRENT TRANSFORMER
(FR) PROCÉDÉ DE PRÉPARATION D'UN TRANSFORMATEUR DE COURANT EN FORME DE PINCE À DEUX ÉTAGES À HAUTE PRÉCISION
(ZH) 一种制备高准确级双级钳形电流互感器的方法
Abstract
(EN) A method for preparing a high-accuracy dual-stage clamp-shaped current transformer, using a dual-stage structure and having a main winding and an auxiliary winding, and being capable of improving accuracy by one order of magnitude, i.e. from an existing 0.2 stage clamp-shaped current transformer to a 0.02 stage, providing technical support for high-precision alternating current measurement applications.
(FR) Procédé de préparation d'un transformateur de courant en forme de pince à deux étages à haute précision, utilisant une structure à deux étages et ayant un enroulement principal et un enroulement auxiliaire, et pouvant améliorer la précision d'un ordre de grandeur, c'est-à-dire d'un transformateur de courant en forme de pince à 0,2 étage existant jusqu'à 0,02 étage, fournissant un support technique pour des applications de mesure de courant alternatif à haute précision.
(ZH) 一种制备高准确级双级钳形电流互感器的方法,采用了双级结构,具有主绕组和辅助绕组,其准确级可以提高1个数量级,也就是能从现有的0.2级钳形电流互感器提高至0.02级,为高精确度交流电流测量应用提供技术支撑。
