Compatible with a 10kV primary and secondary integrated pole-mounted circuit breaker, it meets the power requirements of low-power intelligent FTUs (Feeder Terminal Units), aligning with the integrated design demands of electrical grid equipment. The device features no-load and short-circuit protection in its secondary output, along with high output power, anti-resonance capabilities, compact size, and enhanced reliability and safety.
Application scope
It is suitable for many occasions such as power grid, mine and rail transit, and can provide stable and reliable power supply for all kinds of measurement, protection, control and online monitoring equipment.
Features
· Stable Power Extraction: Utilizes 10kV line voltage for power extraction, unaffected by load current magnitude, ensuring stability and reliability.
· Safe & Reliable: Avoids ferromagnetic resonance, with safety theoretically and practically verified over the long term.
· Energy Efficient & Environmentally Friendly: Significantly lighter than conventional electromagnetic power extraction PTs, reducing the overuse of ferromagnetic and resinous materials.
· Compact & Versatile: Offers integrated design compatibility and convenient installation.
