description: In this work, a study was conducted of the areas of existence of ferroresonant overvoltageâs in 220 and 500 kV switchgear, depending on the voltage transformers used in them. The research results are compared with the areas of existence of ferroresonant overvoltageâs available in the service station. Determination of zones of existence of ferroresonant overvoltageâs was carried out using the EMTP-RV software package for voltage transformers, the characteristics of which coincide with the characteristics of an NKF type transformer, and for special anti-resonance voltage transformers in 220 and 500 kV switchgear. Two types of voltage transformer are used to determine how increasing the knee of the magnetization curve affects the region of existence of ferroresonant overvoltageâs. The work examines the operating modes of switchgear switchgear at the rated and highest operating voltage, which makes it possible to determine changes in the areas of existence of ferroresonant overvoltageâs associated with changes in operating voltage. The results obtained can be used in the design of networks with switchgear to protect equipment from damage caused by ferroresonance phenomena.
