Product Overview

The High Precision Power Harvesting Module is designed for power line monitoring and intelligent electrical measurement applications. It integrates a permalloy magnetic core, a precision winding coil, a durable protective housing, and a specialized clamping structure.

With a 300-turn winding design and high-performance permalloy core, this module provides reliable current sensing and energy harvesting capabilities.

The module supports electric-tool-assisted installation, making it suitable for power line monitoring systems that require convenient installation and stable operation.

We provide customized current transformer and power harvesting solutions to meet different cable dimensions and application requirements.

Key Features

• High-Precision Current Sensing: Typical current sampling accuracy of less than ±0.2% when tested with the corresponding circuit board.

• Efficient Energy Harvesting: At an input current of 1A and a load resistance of 1.8kΩ, the output voltage exceeds 3.1V.

• High-Performance Magnetic Core: Uses a permalloy core with a 10 × 20 mm cross-sectional specification.

• Electric Tool Installation: Designed for installation using a specialized electric installation tool.

• IP68 Protection: Tested at a water depth of 1.5 meters for 36 hours.

• Durable Construction: PC + fiberglass housing and 304 stainless steel spring.

• Wide Operating Temperature: Suitable for operating temperatures from -40°C to +75°C.

Cable Compatibility

The module is designed to accommodate insulated cables with different outer diameters:

• 11–22 mm cable diameter: Rubber pad required.

• 22–28 mm cable diameter: Rubber pad not required.

The clamping structure helps secure the module to the cable during installation.

Mechanical Performance

• Drop Resistance: Withstands three drops from a height of 1.2 meters at 0° without structural breakage.

• Clamping Force: With rubber pad installed, horizontal spring clamping force ≥60N and vertical clamping force >120N.

• Corrosion Resistance: 96-hour medium-level salt spray test.

• Screw Tightening Torque: 7–8 kgf·cm, using a diagonal tightening sequence.

Applications

This high-precision power harvesting module is suitable for: Overhead power line monitoring systems/Smart grid monitoring equipment/Distribution network automation/Intelligent current measurement systems/Power line condition monitoring/Online monitoring devices for electrical infrastructure.
