Energy Harvesting Cores
Our tape wound toroidal cores help enable the power and efficiency required from magnetic energy harvesting devices utilized in high-voltage power lines and smart grids.
Energy harvesting cores maximize the performance of devices such as current transformers (CT), power supplies, sensors, inductors, and AC/DC converters. These devices are used to monitor and harvest energy produced by high-voltage power transmission lines. Using our tape wound energy harvesting cores, produced by our proprietary winding configurations, enables these devices to extract energy and power monitoring systems that measure current, vibration, conductor temperature, and other parameters used in condition monitoring and predictive maintenance programs. Magnetic Metals’ nanocrystalline material provides high permeability and low core losses, making it particularly effective for energy harvesting applications that must operate reliably at lower conductor current levels.
Smart Grids, in particular, require devices powered by our magnetic cores for advanced energy management and communication systems. This enables rapid response to real-time changes in electricity demands. For higher-current applications, grain-oriented silicon steel core materials can provide high flux capability and support efficient energy harvesting across a wide operating range.
Magnetic Metals’ tape wound energy harvesting cores achieve a virtually complete magnetic circuit that enables them to provide the reliability, efficiency and power density required for energy-harvesting devices, while withstanding environmental conditions that could damage their operation. In addition, we carry a broad range of advanced-grade soft magnetic materials and the ability to tailor their properties and performance characteristics to your specifications, with the fastest turnaround in the industry.
Cut-core and split-core configurations are also available for installations on existing conductors where disconnecting the line is impractical or undesirable.
