Введение:
- Three phase electronic energy meters feature a variety of functions, including energy metering, load control, and user information management.
- Our three-phase electronic energy meters measure voltage, current, power factor, frequency, and demand, and support time-of-use (peak, off-peak, and shoulder) and bi-directional metering.
- The electricity meters manufactured by CNTN Electric feature no mechanical moving parts, offering a long service life, low power consumption, and strong anti-interference capabilities; they are adapted to withstand harsh environments ranging from -40°C to +70°C.
- Wiring Methods for CNTN Electric Energy Meters: Classified into Direct Connection (for low currents) and Connection via Instrument Transformers (for high currents).
