Protection set: Digital Protection Relay with Potential Transformer (PT) and Current Transformer (CT)

HVEX Protection System

The relay is primarily used for feeder, recloser, and primary substation protection, featuring functions including protection, control, measurement, communication, data processing, energy management, etc. When associated with electronic transformers, saturation and resonance are eliminated, enhancing electrical endurance. Furthermore, it reduces equipment cost and weight, enabling compact primary substations. It can be combined with internal and external primary equipment, providing a variety of automation solutions compliant with international standards. With a wide range of essential functions for electrical systems, it emphasizes protection, control, measurement, and communication, ensuring operational safety and efficiency. Additionally, it boasts advanced data processing and energy management functions, allowing real-time monitoring and adjustment, including current, voltage, active power, reactive power, apparent power, and up to 11 harmonics. With support for multiple feeder protection functions, the system can record faults and analyze load profiles, facilitating issue detection and resolution, promoting power quality analysis, harmonic verification, and ensuring optimal system performance.
