[0002] Due to the functional requirements of voltage transformers and lightning arresters, voltage transformers must be installed in the main electrical system to measure voltage, instrument voltage and protection voltage, and lightning arresters must be installed for overvoltage and lightning protection. Therefore, voltage transformers and lightning arresters play an important role in the main electrical system. Under normal circumstances, a switchgear whose main components are voltage transformers (including lightning arresters) is called a PT cabinet. However, due to the characteristics of the power grid and different installation and use conditions, voltage transformers and lightning arresters may be installed together with other main components in a switchgear. In order to distinguish it from conventional incoming line cabinets, outgoing line cabinets, and busbar cabinets, it is generally called a busbar PT combination cabinet.
