The CT connection in the LDT302 is a key feature. Current transformers (CTs) play a vital role in accurately measuring electrical current. By having a dedicated CT connection, the smart meter can precisely measure high-current circuits, ensuring accurate billing and energy management. This is especially important in industrial settings where large amounts of electricity are being consumed.
4.2 Optional Auxiliary Power Supply
The option for an auxiliary power supply provides flexibility. In case of power outages or fluctuations in the main power source, the auxiliary power supply can keep the smart meter functioning. This ensures continuous monitoring and data collection, preventing any loss of important energy-related information.
4.3 Ultra-wide Voltage Range
The ultra-wide voltage range of the LDT302 is a significant advantage. It can handle a broad spectrum of voltage levels, which is crucial in industrial and substation environments where voltage can vary significantly. This feature allows the smart meter to operate stably and accurately, regardless of the input voltage, reducing the risk of inaccurate measurements or meter failures.
4.4 Neutral Sensor (Optional)
The optional neutral sensor offers an added layer of functionality. It can provide additional information about the electrical system, such as the balance of the three-phase system. This data can be used for more in-depth energy analysis and system diagnostics, helping to optimize the overall performance of the electrical grid.
4.5 Multiple Anti-tamper
With anti-tamper features for 4G/3G/2G or other wireless connections, the LDT302 ensures the integrity of the measured data. In smart metering, data security is of utmost importance. These anti-tamper measures prevent unauthorized access or manipulation of the meter, safeguarding the interests of both the energy provider and the consumer.
4.6 Delta Package Firmware Upgrade
The delta package firmware upgrade feature allows for easy and efficient updates to the smart meter’s software. As technology evolves, firmware upgrades are essential to keep the meter up-to-date with the latest features and security patches. This ensures that the LDT302 can adapt to new industry requirements and maintain its high-performance standards over time.
4.7 Internal/External Relay Control
The internal/external relay control provides flexibility in managing the electrical circuit. It can be used to control the connection or disconnection of power, for example, in case of emergencies or for load management. This feature is valuable in industrial applications where precise control of power distribution is necessary.
4.8 Smart Meter Exchangeable Battery
The exchangeable battery feature is practical. In the event of a battery failure, it can be easily replaced, ensuring that the smart meter continues to function without interruption. This is especially important for maintaining continuous monitoring and data logging in remote or unmanned substations.
