Correction of the secondary current measuring transformers at saturation


In Russia and the CIS countries, Relematika is known not only for its productsIn Russia and the CIS countries, Relematika is known not only for its Youth Conference of the Academy of Sciences of the Republic of Chuvashia electrical (AES ChR), where six experts spoke from Relematika. Three of them won awards.

Among the speakers - Master of the Faculty of Energy and Electrical Engineering ChGU. I.N. Ulyanova, research engineer of the 2nd category of Relematika LLC, post-graduate student of ChSU named after I.N. Ulyanova Alexander B. Atnishkin. Alexander touched upon a topical problem for the current day: saturation of measuring current transformers, which leads to distortion of the observed current shape by relay protection devices, which ultimately leads to incorrect operation of the protection.

One of the ways to compensate for this negative effect is to correct the current in the saturation areas. The paper considers a method for correcting the current using the observed current of the saturated section.
