The LY-8801 switchgear status indicator is an advanced intelligent switch cabinet monitor designed for comprehensive real-time monitoring of switchgear operations. Beyond basic status display, it integrates high-voltage live indication, environmental monitoring, and fault diagnosis, making it a cornerstone of modern power infrastructure. Engineered by LIYITECH, this device enhances operational efficiency, enables proactive maintenance, and ensures the safety of electrical systems in diverse applications. Its user-friendly interface and versatile functionality make it indispensable for power professionals.
Equipped with high-precision temperature sensors, humidity sensors, and current/voltage sensors, the LY-8801 captures a wide range of operational parameters. It also supports dual temperature and humidity sensors for comprehensive environmental monitoring.
Leveraging AI algorithms, the device processes real-time sensor data to identify trends and predict potential failures (e.g., insulation degradation). This proactive approach reduces unexpected downtime and maintenance costs.
All collected data is stored in the cloud, enabling secure, remote access from anywhere with an internet connection. Facility managers can share data across teams (operations, maintenance) for collaborative decision-making.
The device offers customizable switch status dashboards displaying real-time data, historical trends, and alarms. Detailed reports support performance analysis, compliance, and maintenance planning.
Featuring high-voltage live indication (A/B/C phase) and passive normally closed interlock output, the LY-8801 enhances operational safety by preventing accidental contact with live equipment. It also includes wire break alarm for sensor fault detection.
The LY-8801 operates on AC/DC 110V-220V power supply, with an ambient temperature range of -20℃-65℃. It offers ±1℃ temperature accuracy and 5%RH humidity accuracy, complying with IEC255-22 anti-electromagnetic interference standards.

In power substations, the LY-8801 monitors switchgear status and environmental conditions, ensuring stable power transmission.
Industrial control centers rely on the device for real-time switch monitoring, supporting efficient production operations.
Distribution rooms use the indicator to track circuit breaker status and prevent humidity-related issues, enhancing power distribution reliability.
In solar/wind power stations, the device adapts to variable operating conditions, ensuring safe and efficient switchgear performance.
Ensure the device’s power supply (AC/DC 110V-220V) matches your system’s voltage to avoid malfunctions.
Select the LY-8801 if you need to monitor switch position, live status, energy storage, and environmental conditions simultaneously.
Check that the ambient temperature (-20℃-65℃) and humidity (≤95%RH) ranges align with your application environment.
Opt for the LY-8801 if RS485 communication and cloud data access are required for centralized management.
Fix the indicator to the switchgear cabinet using compatible fasteners; ensure proper alignment with sensors.
Connect power supply terminals to AC/DC 110V-220V (follow wiring diagram).
Wire sensors (temperature/humidity, live detection) to corresponding terminals (12-15 for live sensors).
Connect heating/dehumidification devices to passive normally open terminals and interlock systems to passive normally closed terminals.
View real-time status via LED indicators (yellow/red/green for different states: unenergized/energized, breaker on/off).
Use control I/II buttons to switch between manual and automatic modes for heating/dehumidification.
Initiate self-test to verify sensor and indicator functionality.
If live indication fails, check sensor wiring and pull out terminals during withstand voltage testing.
For communication issues, verify RS485 wiring and network connectivity.
Refer to the fault diagnosis guide for remedial actions if alarms are triggered.
