Introduction:
CT power taking device is a new type of induction power taking device that uses electromagnetic energy induced around high-voltage transmission lines to obtain electrical energy. This device uses the principle of electromagnetic induction, uses a current transformer to directly induce AC voltage from the high-voltage bus, and then undergoes rectification, filtering, and voltage stabilization to obtain a stable and reliable DC voltage to provide a stable power supply for electrical equipment installed nearby. It can ensure the long-term stable power supply of the load equipment. It is suitable as a power supply device for on-line detection, monitoring, inspection, anti-theft and other electrical equipment on high-voltage transmission lines.

Features:
1. Start to take electricity from a small load current and maintain a regulated output.
2. CT with open circuit and high current impact protection, and maintain a regulated output.
3. Open type current transformer structure, easy to install and unload.
4. Insulating shell, epoxy potting, explosion-proof and flame-retardant, safe to use.
5. Replace high-pressure PT, economical and practical.
Application:
- Suitable for motor protection ,relay protection,small current grounding system
- Suitable for electrical fire monitoring systems
- Flexible output method
- Through structure ,epoxy resin casting,good stability
- High permeability permalloy or nanocrystalline ,with good linearity and high sensitivity
- Excellent balance characteristics and extremely strong immunity to electromagnetic fields.split-core current transformers. The CT can be mounted to existing panels, such as control centers or load centers, to measure or monitor wattage. These CTs can be mounted without removing existing cables for easier installation.
