3 Phase Voltage Relay GRV8-03X hangtod 08X

Paggamit sa GRV8-03X hangtod sa 08X series three-phase voltage monitoring voltage relay products:
Ang serye sa GRV8-03X hangtod sa 08X gi gamit kauban sa mga sumusunod nga key areas tungod sa iyang reliable nga performance sa pag-monitor ug flexible nga adaptability:
1. Mobile devices ug special vehicle power management:
Arong makapahibalo og stable nga three-phase power monitoring alang sa on-site engineering equipment, agricultural machinery ( sama sa harvesters, tractors), refrigerated transport vehicles ug uban pang mobile equipment, nagpahigayon og safe ug reliable nga operasyon sa complex ug changing power supply environments ( sama sa generator power supply o temporary power access), ug nagpreventa sa shutdown o damage sa equipment gikan sa abnormal nga voltage.
2. Equipment rotation direction protection:
Accurately monitor ang phase sequence sa three-phase power supply ug maayo nga detect ang phase sequence errors (nga mao ang mahimong magresulta sa reverse rotation sa motor)
Ipadala ang control signals aron maprevent ang mechanical damage, production accidents, o safety incidents gikan sa reverse operation sa mechanical equipment.
3. Automatic Switching System (ATS) for Primary and Backup Power Supply:
Sa mga lugar nga nanginahanglan og high reliability power supply, sama sa data centers, hospitals, ug critical production lines sa factories, gigamit kini aron imonitor ang status sa normal (primary) power supply ug emergency (backup) power supply ( sama sa generators). Kung ang main power supply moguba ( sama sa voltage loss, undervoltage, overvoltage, phase loss), mahimo kini nga reliably trigger ang signal aron drive ang switching device, seamless o brief interruption sa load aron iswitch sa backup power supply, nagpahigayon og continuity sa power supply.
4. Motor ug power load protection:
Real time monitoring sa three-phase power supply alang sa electric motors ug uban pang important power loads. Sa event sa phase failure, mahimo kini nga immediately detect ug output an alarm o cut off control signal, effectively preventing the motor from overheating and burning out due to single-phase operation, ug protecting valuable equipment assets.
5. Industrial production lines ug mechanical equipment protection:
Widely used in various industrial automation production lines, pumps, fans, compressors and other equipment, as a front-end voltage protection unit, to prevent equipment shutdown, production interruption or component damage caused by unstable grid voltage (overvoltage, undervoltage) or phase loss.

GRV8-03X hangtod sa 08X series three-phase voltage monitoring type voltage relay product features:
1. High precision true effective value measurement:
Thru ang paggamit sa true effective value measurement technology, mahimo kini nga maghatag og accurate nga voltage measurement results (accuracy ≤ 1%) even under non sinusoidal voltage conditions containing harmonics, truly reflecting the state of the power grid.
2. Wide voltage adaptability and wiring flexibility:
Provide 8 adjustable rated voltage levels that can adapt to standard grid voltages in different countries and regions around the world. Simultaneously supporting both 3-phase 3-wire and 3-phase 4-wire (3L/3N) wiring methods to meet diverse on-site requirements.
3. Excellent anti-interference performance:
The internal circuit has undergone professional anti harmonic design optimization, and has been strengthened for high interference industrial environments (such as near frequency converters and high-power rectification equipment), effectively suppressing harmonic interference and ensuring the stability and reliability of monitoring.
4. Intuitive status indication:
Equipped with high brightness LED indicator lights, it clearly displays the current working status of the relay (such as power supply, faults, alarms, etc.), making it easy for on-site personnel to quickly identify the system's operating status.
5. Ultra compact design:
Adopting an ultra-thin design with a width of only 18mm, it greatly saves installation space inside the control cabinet. Supports standard 35mm DIN rail installation, with easy and quick installation and disassembly, suitable for high-density wiring applications.
