IEEE C57.13.5-2019 IEEE Standard for Performance and Test Requirements for Instrument Transformers of a Nominal System Voltage of 115 kV and Above

IEEE C57.13.5-2019 Стандарт IEEE для повышения производительности и испытаний Требования к приборам Трансформаторы Номинальное напряжение 115 кВ и выше

This standard is intended for use as a supplement to IEEE Std C57.13-2016 and as a basis for performance and safety of equipment.1 It also describes test sequences, criteria, methods, and documentation for tests. This standard applies to single-phase instrument transformers of a nominal system voltage of 115 kV and above with capacitive insulation system for line-to-ground connection and for both indoor and outdoor application.
