Therefore, the disruptive critical voltage for middle conductor will be less, that is V0 will be less, that means, 2 will be higher; therefore, the middle conductors your corona loss will be higher than the your what you call your hence there will be more corona loss in middle conductor than the outer 2 conductor, this is the reason.
त्यामुळे मधल्या कंडक्टरमध्ये डिसृप्तींव क्रिटिकल वोल्टेज V0 कमी असेल म्हणजे 2 जास्त असेल. त्यामुळे मधल्या कंडक्टर मध्ये होणारा कोरणा लॉस बाजूच्या कंडक्टरपेक्षा जास्त असेल.
