With the rapid development of economy, the electricity demand increasing, the power stability & uninterrupted are more and more important. It's imminent to online real-time monitoring on high-voltage transmission lines to guarantee the safe and stable operation of transmission lines.  The high voltage inductive power supply is the best choice for online equipment functions, because is suitable for different climates, stable&reliable power supply, maintenance-free operation. Today, let’s talk about the inductive power supply.

The inductive power supply (Energy Harvesting Coil) is a device, that use the CT installed on the power line to obtain power through the electromagnetic induction principle. It's combined by current transformer (enrgy-taking transformer) and power conversion module (Converting the electrical energy obtained by CT into the required DC voltage) two parts.

• Anti-rust treatment

Under the premise of the performance of the magnetic core is not affected，our cores passed high standard salt spray test, which guarantee the core with excellent rust-proof ability.

• Mirror Cut

All our cores cutting surface as smooth as mirror. To achieve this appearance:

We imported curing glue, improving the core hardness & reducing the cutting surface defects. We improved cutting processes, vertically centered cutting surface, and the formula of the cutting blade is adjusted to achieve the mirror cutting effect, which is basically the same as the performance before cutting.

• Flat winding

When winding, we precise machine winding number and tension to ensure winding coils flat.

Advantage of Energy Harvesting Coil

• No special installation required
• Small size, canintegration with monitoring equipment
• Simple insulation design
• contactless electricity
• Installation without power outage
• Disadvantage
• Output power limited by line current
