Din Rail Meter -Knowledge About Rail Type Electric Energy Meter The rail-type electric energy meter is currently used for the installation of the terminal electric energy meter. The traditional wall-mounted installation method is generally used, which has the disadvantages of large volume and inconvenient installation. The rail-mounted ammeter adopts a modular design, which has the advantages of small size, easy installation, and easy networking. It is easy to implement the terminal lighting energy measurement, and it is convenient for the retrofit of the lighting system with an installed electricity meter. Rail mounted energy meter is a new generation of mini smart energy meter. It is used for 380V / 220V terminal lighting system. It adopts standard DIN35mm rail type installation. The structure is modular design. The width is matched with the miniature circuit breaker. It can be easily installed in the lighting box. . The meter uses LCD display to measure electrical energy and other electrical parameters. It can be used to set parameters such as clock and rate periods, and has an energy pulse output function. The RS485 communication interface can be used to realize data exchange with the host computer. The rail-mounted energy meter has the advantages of small size, high precision, good reliability and easy installation. The performance indicators meet the technical requirements of the national standard GB / T 17215, GB / T 17883 and the power industry standard DL / T614 for the energy meter. It is suitable for the sub-metering of electric energy in government agencies and large-scale public construction, and it can also be used for evaluation of electric energy management in enterprises and institutions.

Knowledge About Three Phase Meter Definition: An electric meter used to measure the power of a three-phase power source is called a three-phase electric meter. A three-phase electric meter is constructed by connecting two single-phase electric meters through a shaft. The total energy is the sum of the readings of the two elements. Working principle of three-phase electricity meter Mechanically increasing the torque of the two components, the total rotation of the shaft is proportional to the three-phase energy consumption. Construction of three-phase electricity meter The three-phase meter has two disks installed on a common shaft. Both discs have their brake magnets, copper ring, shading tape and compensator to get the correct reading. These two elements are used to measure three-phase power. The structure of the three-phase electricity meter is shown in the figure below. For a three-phase electricity meter, the driving torque of the two components is equal. This can be done by adjusting the torque. By connecting the current coils of two components in series and their potential coils in parallel, the torque can be adjusted. Full-load current flows through the coil, so two opposing torques are established in the coil. The strength of the two torques is equal, so they do not allow the disc to rotate. If the torque becomes unequal and the disc rotates, then the magnetic shunt will be adjusted. Balance torque has been obtained before testing the meter. The position of the compensator and the brake magnet are adjusted to each element separately to obtain a balanced torque.
