Feature of 3 phase smart meter
- Three-phase voltage, current, apparent power, power factor, frequency, active energy, and reactive energy measurements
- Four different types of rates and up to eight time periods per day are possible with multi-rate energy statistics. The function of historical power statistics
- Rated current A 10-100A LED shows the following: one road passive optical coupler collector active pulse output; default Modbus protocol; optional WiFi connectivity; phase failure; reverse power; and communication status.
- A variety of power metrics and information are displayed on a 7 +1 bit LCD.
- Real-time monitoring, an integrated clock, a maintenance-free battery, and data that is saved indefinitely after a power outage
- Installation of a conventional DIN rail measuring 35 mm is attractive and simple.
Relay included optionally for remote control
Applications of three phase smart meter
- In power systems with medium and low voltages
- Defend circuits from defects such as overload and short circuit.
- Within an industrial control system
- Safeguard other equipment, such as transformers and motors.
- utilized in developing electrical systems for homes, businesses, and industries
- used to safeguard communication connections, equipment, etc.
- Electrical system of renewable energy devices, like solar and wind power
- Make certain that electrical equipment operates safely.
