The method determines a type of a fault in a line segment of the ungrounded power distribution system, and modifies a nodal admittance matrix of the line segment determined before the fault using a transformation matrix corresponding to the type of the fault to produce a faulty nodal admittance matrix of the line segment after the fault. The ungrounded power distribution system is analyzed using the faulty nodal admittance matrix and nodal admittance matrices of functional branches or line segments of the power distribution system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for analyzing faults in ungrounded power distribution systems","description":"A method analyzes a fault of an ungrounded power distribution system.
