This product is mainly composed of two parts of the combined transformer and the meter box, the combined transformer is composed of two or three single-phase voltage transformer and current transformer, with 25#transformer oil as the insulating medium, the first and second outlet end are installed on the panel witn porcelain bushing. The watt-hour meter box is mounted on the side of the combined transformer and consists of a walt-hour meter and a reactive walt-hour meter. It has the advantages of high measuring accuracy, light weight, convenient installation and anti-theft.
This series of electric energy metering box is suitable for outdoor rated voltage 6, 10, 35kV, rated frequency 50Hz three-phase system network.
Product Advantage |
1. Supports dual current ratios to adapt to varying power loads at different periods.
2. When used with a bidirectional metering box, it enables network metering (separate measurement of power generation and consumption).
3. Features high accuracy, compact size, reliable insulation, excellent heat dissipation, stable operation, and easy wiring.
4. A wide range of models is available to meet customized requirements.
