26mm Split-Core Power Harvesting Current Transformer for Overhead Power Line Monitoring

26mm Split-Core Power Harvesting Current Transformer for Overhead Power Line Monitoring

Product Overview

The 26mm Split-Core Power Harvesting Current Transformer is designed for applications requiring energy harvesting from overhead power lines. Its split-core structure allows the transformer to be installed around an existing conductor without disconnecting the primary cable, subject to the installation requirements of the specific model.

This power harvesting current transformer can be integrated into suitable power line monitoring systems to provide harvested electrical energy for compatible electronic devices. Actual output performance depends on the primary conductor current, operating conditions, transformer design, and connected load.

Working Principle

When AC current flows through an overhead power line, it generates a magnetic field around the conductor. The magnetic core captures this magnetic field, and the secondary winding converts the induced magnetic energy into electrical energy.

The harvested energy can be used as an auxiliary power source for compatible monitoring equipment, sensors, and communication modules. Actual output power depends on the primary line current, core characteristics, winding configuration, connected load, and power conditioning circuit.

Feature

1. The harvesting energy CT is of open structure, easy to install and operate.

2. The inner diameter of the transformer can be selected according to the diameter of the primary high voltage line.

3. Transformers of different types and sizes can be matched according to the current of the primary side high voltage line.

4. Energy transformers and induction power modules are used.

5. Rational planning of load distribution according to the conventional operating values and power curves of the conductor currents.

6. Due to the magnetic circuit, there will be a slight ticking sound when the energy transformer is working, which is a normal phenomenon.
