Application of Intelligent Instrument in Low Voltage Monitoring

Application of Intelligent Instrument in Low Voltage Monitoring What is the application of smart meters in low-voltage monitoring systems? All human activities must be inseparable from power, and the distribution of power networks is very common. At present, there are mainly the following three ways in the field of low-voltage power monitoring.

1, through the circuit breaker, contactors, thermal relays, fuses, control relays, a variety of master electrical appliances, transformers and a variety of electrical instrumentation (ammeter, voltmeter, power meter, energy meter, etc.) combination of low-voltage switch control Cabinets to realize functions such as distribution, control, protection and monitoring;

2. Use all kinds of current, voltage, power and other transmitters, access PLC to build low-voltage distribution monitoring system;

3. Adopt a powerful centralized RTU to integrate the on-site signals into the central control room for monitoring.

These three traditional methods all present many shortcomings today: traditional switch cabinets need to be equipped with a variety of analog pointer instruments and relays; it is inconvenient for production, storage, and maintenance, and it is mainly based on manual direct operation. Unable to implement intelligent computer management, it is difficult to implement more complex control logic. The use of a wide variety of transmitter wiring is complex. If you need to collect the 4-20mA analog signal from the transmitter, you also need to access the PLC or an on-site industrial PC to increase the cost of the system and have a high failure rate. It is difficult to upgrade and maintain the monitoring system structure that integrates the signals of multiple lines into a centralized RTU. If the RTU fails, the entire system cannot operate. At the same time increase the cost of field cables.
