- High – Precision Measurement: The REF615C – D HCFFAEAGABC2BAA1XD has an accuracy class that ensures precise measurement of electrical parameters. In a power substation, it can detect even small changes in current and voltage, enabling early detection of potential faults. For example, it can detect a 0.1% change in current, which is crucial for preventing major power outages.
- Flexible Configuration: It allows for easy configuration of protection and control functions. In a complex power distribution network, engineers can customize the relay’s settings according to the specific requirements of different sections of the network. This flexibility reduces the need for multiple types of relays, simplifying the system design.
- Reliable Communication: With multiple communication interfaces such as Ethernet, IEC 61850, and Modbus RTU, the relay can communicate effectively with other devices in the power system. In a smart grid application, it can transmit real – time data to a central control center, enabling remote monitoring and control.
- Application Areas: The REF615C – D HCFFAEAGABC2BAA1XD is used in power generation, transmission, and distribution systems, including power plants, substations, and industrial power networks.
- Application Case: In a large industrial power network, the REF615C – D HCFFAEAGABC2BAA1XD was installed to protect a critical transformer. When a short – circuit fault occurred in the transformer, the relay detected the abnormal current within milliseconds and quickly tripped the circuit breaker, isolating the fault. This action prevented further damage to the transformer and minimized the impact on the industrial production process. As a result, the production downtime was reduced from several hours to just a few minutes.
Compared to similar products in the market, the REF615C – D HCFFAEAGABC2BAA1XD offers higher – precision measurement, which is essential for accurate fault detection. Its flexible configuration options provide more customization possibilities compared to some competitors. The reliable communication interfaces also give it an edge, as they enable better integration into modern smart grid systems.
