Multifunction Digital Protection Relay

The HVEX Multifunction Digital Protection Relay is the ideal solution for protection, monitoring, and control of electrical systems in overhead lines, cables, transformers, and medium-voltage switchgear (10 kV to 40.5 kV). Designed to provide safety, reliability, and automation, the device integrates protection, current measurement, voltage measurement, temperature monitoring, fault recording, and power quality analysis into a single unit. With support for communication protocols such as Modbus, IEC 101/104, and DNP3.0, the relay enables full integration into supervisory and control systems (SCADA), ensuring operational efficiency and reliable energy management. It also features advanced ANSI functions such as overcurrent, overvoltage, undervoltage, sensitive ground fault, overfrequency, underfrequency, and automatic reclosing, ensuring comprehensive protection of electrical assets. Key benefits of the HVEX Relay include: • Accurate measurement of current, voltage, and power with high reliability. Event and disturbance recording with capacity for thousands of data entries. • Intuitive LCD display interface for real-time local monitoring. • Distribution automation, including loop schemes and reclosing. • Robust construction with IP54 front panel protection, ideal for critical environments. • Compliant with international standards IEC 60255, IEC 60947, IEC 60076, and NBR IEC 60529, the HVEX Protection Relay ensures electrical safety, energy efficiency, and technical compliance in industrial and power applications. With HVEX technology, your company benefits from a high-performance multifunction digital relay capable of reducing unexpected failures, optimizing predictive maintenance, and extending the lifespan of transformers, cables, and switchgear.
