What Does a Meter Consist Of?
A smart meter is mainly composed of three parts: switch, measure, and assembly. Within these categories, several key components play a crucial role, including the Latching Relay, Current , and manganin .

1. The Switch: Magnetic Latching Relay
At the heart of a smart meter’s functionality is the switch, which is often facilitated by a Magnetic Latching Relay (MLR). This component is essential for controlling the flow of electricity to and from the meter. Unlike traditional relays, which require continuous power to maintain their state, magnetic latching relays use a magnetic field to hold their position. This feature allows them to consume less energy, making them an ideal choice for smart meters.

2. The Measure: Current Transformer and Manganin Shunt
The measurement component of a smart meter is critical for accurately gauging energy consumption. Two primary elements involved in this process are the Current Transformer (CT) and the manganin shunt.

Current Transformer (CT)

The Current Transformer is a vital component that allows the smart meter to measure the current flowing through the electrical circuit. It operates on the principle of electromagnetic induction, where the primary current generates a magnetic field that induces a proportional current in the secondary winding of the transformer. This transformation allows for safe and accurate measurement of high currents without the need for direct electrical connections.
CTs are particularly advantageous in smart meters because they can provide real-time data on energy consumption, enabling users to monitor their usage patterns.

Manganin Shunt

Another critical measurement component is the manganin shunt. This device is used to measure the voltage drop across a known resistance, allowing the smart meter to calculate the current flowing through the circuit.
The manganin shunt is particularly effective in smart meters because it can handle high currents while maintaining stability and precision.

3. The Assembly: Integration of Components
The assembly of a smart meter involves the integration of the switch, measurement components, and additional circuitry that facilitates communication and data processing. This assembly is designed to ensure that all components work seamlessly together to provide accurate and timely information.

Conclusion
In summary, a smart meter consists of three main parts: switch, measure, and assembly. The Magnetic Latching Relay serves as the switch, providing efficient control over energy flow. The measurement components, including the Current Transformer and manganin shunt, ensure accurate monitoring of energy consumption. Finally, the assembly integrates these components, enabling communication and data processing that enhances energy management.

The centralized quarantine period for inbound international travelers and close contacts of confirmed cases has been shortened from 14 days to 7 days.
Inbound travelers only need to undergo centralized quarantine at hotels for 7 days, instead of 14 days, and then spend 3 days rather than 7 days of self-quarantine at home, according to a document released by the State Council, the country's Cabinet, on 28th June.
