Application Summary AI generated
GB/T 23755-2009 specifies technical requirements, test methods, and acceptance criteria for three-phase site-combined power transformers, which are designed for on-site assembly of individual phase units. This standard is applied in large-scale power transmission and distribution projects, such as hydropower plants or substations, where single-phase transformers are transported separately and combined at the installation site to form a three-phase unit. It ensures performance, safety, and interoperability in high-voltage electrical systems where conventional three-phase transformers cannot be transported due to size or weight constraints.
