Ferroresonant overvoltages can occur in any system ranging from 3 kV to 220 kV; this is particularly true in power grids rated at 35 kV and below, where almost all internal overvoltage incidents are caused by ferroresonance. The overvoltages induced by ferroresonance are long-lasting and may even persist for extended periods. During sub-harmonic resonance, the overvoltage magnitude is generally not high; however, the current flowing through the Potential Transformer (PT) is substantial, making the PT susceptible to overheating and subsequent explosion. Conversely, during fundamental-frequency and super-harmonic resonance, the current is typically low, but the resulting overvoltage is extremely high, frequently causing damage to equipment insulation and leading to severe accidents.<\/li>\n<\/ul>","protected":false},"featured_media":3496,"comment_status":"closed","ping_status":"closed","template":"","meta":[],"product_brand":[],"product_cat":[57,124],"product_tag":[170,171,172,173],"class_list":{"0":"post-3720","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-high-low-voltage-components","7":"product_cat-microcomputer-harmonic-elimination","8":"product_tag-harmonicsuppressor","9":"product_tag-photovoltaic","10":"product_tag-powerstation","11":"product_tag-transientovervoltage","13":"first","14":"instock","15":"shipping-taxable","16":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/product\/3720","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/comments?post=3720"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/media\/3496"}],"wp:attachment":[{"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/media?parent=3720"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/product_brand?post=3720"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/product_cat?post=3720"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/ottai-power.com\/es\/wp-json\/wp\/v2\/product_tag?post=3720"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
