In 33kV/35kV high-voltage outdoor distribution systems, tentsio-transformadoreak (PTs) are core equipment for energy metering, voltage monitoring, and relay protection, directly affecting the accuracy of electricity billing and rapid clearing of grid faults. They must have extremely high measurement accuracy, long-term stability, and strong environmental adaptability to cope with global complex climate challenges including high temperature, high humidity, gatz spray, kutsadura handia, and high altitude. Traditional PTs often suffer from oil leakage, rapid oil aging, accuracy drift, and high pollution flashover risk, which are difficult to meet the harsh requirements of outdoor high-voltage scenarios.
