Introduction
Globally, Transmission System Operators (TSOs) face the challenge of maintaining the stability and reliability of the electric power grid. To address this, they employ a variety of tools and technologies such as load cells and weather stations—to help prevent outages caused by extreme storms or mechanical failures. However, installing and maintaining these systems in the most vulnerable locations remains particularly challenging.
These high-risk areas are often remote, accessible only by helicopter or require a six-hour drive or longer. Transmission lines in these regions are especially susceptible to outages because they lack real-time, robust monitoring systems. Moreover, the existing monitoring systems which are powered by batteries or solar panels, often prove unreliable because of power fluctuations and weak communication signals.
An example of a complex setup on a remote transmission line that combines multiple power sources to energize monitoring devices.
This article delves into Laki Power´s innovative patented power-harvesting technology, which harnesses transmission line current to energize monitoring devices equipped with high-definition cameras, line sensors, a weather station and communication capabilities. This breakthrough solution enables reliable, real-time monitoring of remote transmission lines, thereby enhancing grid stability and preventing power outages.
What is induction-based power harvesting?
Induction-based power harvesting from transmission lines captures energy from the electromagnetic field surrounding AC conductors. When alternating current flows through a power line, it creates a changing magnetic field. Placing a coil or similar inductive element near the conductor induces a voltage in the coil. This voltage is then converted into a stable DC output, which can be used to energize devices.
How does Laki Power´s patented power harvesting technology work?
Laki Power’s patented power harvesting technology employs an advanced cold rectification and regulation technique that minimizes energy losses and heat generation providing an environmentally friendly and stable power supply for sensors and cameras. With all components integrated into a single, self-contained device, installation and operation are simple and efficient. This non-invasive solution effectively extracts power from existing transmission infrastructure, eliminating the need for external sources such as diesel generators or solar panels.

AC to DC Conversion without Heat Waste: Using a cold regulation and rectification process combined with induction techniques, our system efficiently converts AC to DC with nearly 99% efficiency. Unlike conventional methods that waste energy as heat through power dump resistors, our technology only draws the power it needs, with no excess heat generated.
High efficiency Dynamic Power Harvesting: Depending on the conductor current, Laki Power´s technology can extract over 100W of power, with real-world observations showing up to 300W. This high-power output allows the system to dynamically allocate energy to critical components:
Communication: Ensuring reliable, real-time connectivity with mobile and satellite.
Sensors and Cameras: Providing always-on operation for continuous real-time data collection.
Heaters: In sub-zero temperatures, heaters are activated to maintain sensor and camera functionality. The system smartly manages power, prioritizing essential components to keep the network operational even in harsh conditions. Our devices have performed in environments as cold as -40°C in Canada and as hot as 50°C in Saudi Arabia.
Key Advantages of Laki Power’s Technology
Laki Power’s induction-based power harvesting delivers unparalleled situational awareness by integrating sensors, weather data, video, and image data into one compact device. This consolidation streamlines operations and eliminates the need for multiple separate systems. Acting as a single source of truth, the Laki Power device provides detailed, localized data for more informed decision-making.
Cost-effective and environmentally friendly: By eliminating the need for costly external power installations and reducing energy waste, this technology offers significant cost savings and lowers the environmental impact compared to traditional power sources like diesel generators.
Reliable in extreme weather conditions: The system's ability to efficiently harvest high power and dynamically manage energy distribution makes it ideal for remote or harsh environments. Whether it's activating heaters in freezing weather or cooling systems in high temperatures, continuous operation and real-time communication are maintained.
Enhanced Device Health Monitoring: Integrated sensors track temperatures, currents, and other critical metrics within the devices. This proactive monitoring enables early detection of potential issues, ensuring the system remains operational and reliable over time. Why Laki Power’s Non-Invasive Induction Technique is Superior
Windy conditions captured by the LKX-MULTI monitoring device.
Laki Power’s devices generate roughly 10-20 times as much power as competing market solutions, enabling comprehensive and reliable data collection. These monitoring devices capture a wide range of data points—including wind speed and direction—to give TSOs deeper insights into grid capacities, conditions, and critical weather parameters. This precise, in-depth information drives cost-effective decision-making and operational efficiency.
We measure and observe many parameters with precision as opposed to having a limited number of measurements with variable quality and then “guessing” the rest. Óskar Valtýsson, co-founder & Chief Technology Officer
