Ganus O. Operational reliabiliti improvement of voltage transformers in the electrical networks with the isulated neutral

Processes in the electrical networks with the isolated neutral with various high-voltage transformers. Reliability improvement of the electrical network operation at the cost of damageability reduction of voltage transformers. Theoretical methods of the electrical networks and mathematical analysis, mathematical statistics and theory of reliability, approximation, nonlinearity and mathematic simulation. The selection recommendations on voltage transformer types are developed, the suppression methods of ferroresonant processes are proposed. The influence of magnetic characteristics of voltage transformers on their damageability is determined and the recommendations on their removal are developed. The authenticity of theoretical conclusions is proved by experiments. The results have been implemented in JSC "Kharkovoblenergo", "Poltavaoblenergo", "Lvovoblenergo". Electroenergetics
