description: This work is devoted to the search for the cause of the fuse triggering at the 35 kV voltage measuring transformer when operating in a network with an isolated neutral, to development the computer model of the transformer and the analysis of transient processes under various operating modes of the network. Tasks that were solved during the research: 1. Creation of a computer model of an antiresonant measuring voltage transformer 35 kV NALI NTZ-35; 2. Carrying out computer model tests according to PNST 319-2018; 3. Calculation of transients taking into account the parameters of the network in which the fuses were triggered. As a result of the work done, transients were calculated that can cause to the operation of 35 kV 300 mA fuses of 35 kV NALI NTZ-35 voltage transformers installed in a network with an isolated neutral at 35 kV Magistralnaya SS and 35 kV Sychevskaya SS. As a solution to the problem, a high-resistance resistive neutral grounding at 35 kV Magistralnaya substation is proposed.
