This Oil Immersed Combined Instrument Transformer, also known as an oil-immersed high-voltage metering box, is independently developed by Anqiang Electric and is suitable for both indoor and outdoor use. The three-phase three-wire metering box consists of two single-phase voltage and current transformers, while the three-phase four-wire metering box consists of three single-phase voltage and current transformers. These are installed in a box enclosure, with the primary and secondary terminals using porcelain bushings mounted on the panel. An electricity meter is installed on the outer surface for metering purposes.
