In today’s fast-paced industrial and commercial environments, efficient energy monitoring is more critical than ever. Go Monitor is excited to spotlight the innovative CT101 and CT103 self-charging, LoRaWAN® current transformers from Milesight. These devices represent a significant step forward in wireless energy monitoring, offering precise current measurement, seamless IoT connectivity, and unmatched ease of installation—all key factors in energy saving and submetering strategies.

Innovative Energy Monitoring at Its Best
The CT101 and CT103 current transformers are engineered to deliver real-time monitoring of electrical current flow, making them ideal for applications ranging from residential properties, smart buildings to manufacturing facilities and beyond. With a high sampling frequency of 3.3 kHz, these LoRaWAN current transformers capture accurate RMS current and accumulated energy data. This precision in energy monitoring is crucial for identifying inefficiencies, detecting early signs of equipment failure, and supporting proactive maintenance programs that lead to significant energy saving over time.

Self-Charging and Battery-Free Operation
One of the standout features of the CT101 and CT103 is their self-charging capability. By drawing power from the magnetic field around the measured circuit, these sensors eliminate the need for batteries or external wiring. This innovative design not only reduces maintenance and replacement costs but also supports a more sustainable and maintenance-free operation. The result is a reliable solution for continuous wireless energy monitoring without the typical power interruptions.
Seamless IoT Integration and Remote Management
Communication and data management are essential in modern IoT ecosystems. Both the CT101 and CT103 are fully LoRaWAN® enabled, ensuring effortless integration with existing gateways and network servers. This compatibility supports reliable, long-range data transmission for wireless energy monitoring. When paired with the Go Monitor Cloud Platform, facility managers can remotely monitor energy usage via an intuitive web dashboard. This real-time insight into energy consumption not only facilitates submetering but also empowers users to set threshold alarms and receive instant alerts on irregular current flows—making energy saving strategies more proactive and data-driven.
Enhancing Accuracy with Complementary IoT Devices
When combined with a smart plug such as the WS523, these CT current transformers gain an additional edge. The integration introduces a voltage reference that, together with the accurate current measurements from the CT101 and CT103, allows for an even more comprehensive analysis of power usage. This synergy is particularly beneficial in energy monitoring and submetering applications where precise calculations of power consumption are critical for driving energy saving initiatives. The additional voltage reference ensures that power usage is calculated with heightened accuracy, providing businesses with deeper insights into their electrical consumption patterns and enabling them to optimise operational efficiency.
Benefits Beyond Energy Monitoring
Beyond their impressive measurement capabilities, the CT101 and CT103 offer multiple benefits that extend into every facet of facility management. Their self-powered design minimises energy waste and lowers overall operational costs, while the non-invasive installation minimises risks during deployment. With high-accuracy data collection and IoT connectivity, these devices are an essential component in modern energy management systems. They enable effective submetering by allowing businesses to monitor specific areas or devices, ensuring that every watt is accounted for and optimised towards their energy saving goals.
