Description

The GRV8-03 to 08 series three-phase voltage monitoring relays are key components for ensuring stable operation and equipment safety of three-phase power systems. Its high-precision measurement, flexible configuration options, reliable protection functions, and compact design make it perform well in various application scenarios such as industrial automation, mobile devices, power switching, and power protection. Choose the GRV8 series to provide a professional and reliable voltage monitoring solution for your electrical system.
GRV8-03 to 08 series three-phase voltage monitoring relay product features:
1. True RMS measurement:
By using true effective value measurement technology, it can accurately reflect the actual voltage waveform of the power grid, effectively respond to voltage monitoring needs in harmonic distortion or waveform distortion environments, and provide more reliable protection benchmarks.
2. Wide range rated voltage options:
Provide 8 standard rated voltage specifications (GRV8-03 to 08) to choose from, covering mainstream industrial voltage levels worldwide, with good global applicability, simplifying equipment selection and inventory management.
3. Flexible wiring methods:
Supports two common three-phase system wiring methods, 3-phase 3-wire (Delta) and 3-phase 4-wire (Wye/Star), to adapt to different distribution network structures.
4. High precision voltage monitoring:
The voltage measurement accuracy is controlled within ≤ 1% to accurately determine the system voltage status and avoid misoperation or protection failure.
5. Intuitive status indication:
Equipped with high brightness LED indicator lights, it clearly displays the current working status of the relay (such as power supply, fault type, output status, etc.), facilitating quick on-site diagnosis and maintenance.
6. Compact design, space saving:
Adopting ultra-thin design, with a width of only 18mm, it supports standard 35mm DIN rail installation, saving valuable installation space inside the control cabinet, especially suitable for space limited occasions.

Advantages of GRV8-03 to 08 series three-phase voltage monitoring relays:
1. Wide applicability:
Multi voltage specifications and dual wiring mode design meet the application needs of different regions and systems worldwide.
2. High reliability:
The combination of true effective value measurement technology and high-precision monitoring ensures the accuracy and timeliness of protective actions in various complex power grid environments.
3. Easy installation:
The ultra-thin and compact body and standard DIN rail installation method simplify the installation process and save control cabinet space.
4. Maintain intuitive:
Clear LED status indication facilitates quick understanding of equipment status by operators and facilitates troubleshooting and maintenance.
5. High cost-effectiveness:
The three-phase voltage monitoring and protection function provided at a reasonable cost effectively reduces the risk of equipment failure and maintenance costs.
