उल्लोल संरोधाचे समीकरण याद्वारे दिले जाते

जेथे, L = हेन्रीमध्ये प्रेरितता

C = फॅराडमध्ये धारिता

एक संरोध जो रेषा अनंत रेषा म्हणून दर्शवतो त्याला उल्लोल संरोध म्हणून ओळखले जाते. त्याचे मूल्य सुमारे 400 ओहम आणि ओव्हरहेड रेषेसाठी 0 ते -15 अंश आणि भूमिगत केबल्ससाठी सुमारे 40 ओहम पर्यंत बदलणारा प्रावस्था कोन आहे.

ओव्हरहेड लाईनसाठी उल्लोल संरोध 400-600 Ω द्वारे दिला जातो

भूमिगत केबलसाठी उल्लोल संरोध 40-60 Ω द्वारे दिला जातो
