Looking for Wireless Switchgear Temperature Monitoring?
If you are searching for:
- switchgear temperature monitoring
- wireless switchgear temperature sensor
- wireless temperature monitoring for electrical cabinets
- MV switchgear temperature monitoring
- medium voltage switchgear temperature sensor
- electrical contact temperature monitoring
- busbar temperature monitoring
- circuit breaker contact temperature monitoring
The Acrel ATE400 + ATC600-C solution is designed for monitoring temperature at electrical connection points inside switchgear.
ATE400 can be installed at electrical joints such as breaker contacts, busbars and cable connections, while ATC600-C receives the wireless temperature data and provides RS485 communication to the upper-level device or monitoring system.
You may need this solution if:
- You need temperature monitoring without running signal cables from every measuring point.
- You need to monitor multiple switchgear cabinets from a centralized device.
- You need temperature data available on a local display or monitoring system.
- You need a sensor suitable for breaker contacts, busbars or cable connections.
Solution Architecture
Electrical Connection → ATE400 → ATC600-C → Display / Monitoring System
This architecture is particularly suitable when multiple switchgear cabinets require centralized temperature monitoring.
The uploaded project materials show applications involving high-voltage switchgear breaker contacts, busbar connections and cable connections, with wireless temperature data collected and uploaded to power monitoring systems.
Local Temperature Display
ATE400 → ATC600-C → Display Device
For projects that mainly require local temperature viewing and alarm indication.
Centralized Monitoring
ATE400 → ATC600-C → Gateway → Monitoring System
For projects where temperature data needs to be integrated into an existing power monitoring system.
Larger Switchgear System
Multiple ATE400 Sensors → Multiple ATC600-C / ATC600-Z → Monitoring System
For larger switchgear installations where the wireless network needs to be expanded.
The project materials specifically document ATC600-Z as a LoRa relay device, with relay distance stated as up to 1000 m in open areas.
Why Monitor Electrical Connection Temperature?
Electrical connection points inside switchgear can be important temperature monitoring points, including:
- Circuit breaker contacts
- Busbar connections
- Cable connections
- Busbar-to-cable joints
The Acrel solution focuses on direct temperature measurement at these electrical connection points, rather than simply monitoring the ambient temperature inside the cabinet.
This allows temperature data from multiple measuring points to be collected and presented through a centralized architecture.
