1. Background

In the busy workshops of factories and the sprawling industrial parks, energy consumption is like an invisible network connecting production efficiency and operational costs, serving as a core indicator of green development. Acrel’s IoT electric meters, with their integrated capabilities of “metering + IoT + analysis,” combined with the AcrelEMS energy management platform, break down the information silos of traditional energy management, providing factories and parks with precise, efficient, and sustainable digital energy management and power operation solutions.

As the construction of new power systems accelerates, power operation and maintenance have become a core aspect of ensuring the safe and stable operation of the power grid. With the increasing complexity of distribution system structures and the growing number of electrical devices, traditional operation and maintenance models are gradually revealing many pain points:

1. Low efficiency of manual inspections, with data collection prone to errors and delays;

2. Distributed distribution nodes, requiring individual confirmation for fault diagnosis, leading to inefficiency;

3. Potential risks such as line overloads and equipment anomalies are difficult to detect, and once a power outage occurs, it directly impacts industrial production, residential life, and commercial operations.

How can we overcome these challenges and achieve the digital and intelligent upgrade of power operation and maintenance? The Acrel ADW300 wireless metering instrument, with its core advantages of precise metering, real-time monitoring, and flexible adaptation, combined with the AcrelEMS energy management platform, becomes a “breakthrough tool” for energy management and power operation and maintenance.

2. Case Study

In an economic development zone, dozens of manufacturing enterprises are gathered, with the park’s distribution network covering 15 distribution rooms and over 500 electrical circuits. Since the introduction of the ADW300 wireless metering instrument, the park’s energy management has achieved a “qualitative leap”:

1. Real-time monitoring, saying goodbye to manual meter reading: The ADW300 accurately collects electrical data from each circuit and uploads it in real-time to the AcrelEMS energy management platform via 4G wireless communication, allowing maintenance personnel to check the power consumption status of the distribution system at any time, significantly improving efficiency.

2.Fault warning, reducing troubleshooting time: The instrument can monitor line temperature in real-time, and when the line exceeds the temperature threshold, the platform immediately triggers an alarm and locates the fault point, enabling maintenance personnel to quickly complete troubleshooting and repairs, greatly reducing fault response time.

3.Energy consumption analysis, optimizing operation and maintenance costs: By using the ADW300 to collect power consumption data, high-energy consumption segments can be accurately identified, guiding enterprises to save energy, increase efficiency, and reduce costs.

3. Product Features

lFlexible installation, adaptable to various spaces: Adopting a standardized design for 35mm DIN rail, combined with two voltage acquisition modes (magnetic power and piercing power) and open-type current transformers, it can be installed without power interruption on-site, shortening the installation cycle;

lStrong environmental adaptability, stable operation without interruption: The ADW300 can withstand strong electromagnetic interference and significant temperature variations in harsh environments;

lMulti-communication compatibility: Supports various wireless communication methods such as 4G, Wi-Fi, and LoRa, without the need to build an additional transmission network.
