Acrel ATE400: Wireless Temperature Monitoring for Thailand's Substations & Distribution Rooms
Dec 29, 2025
For substations and distribution rooms—critical to Thailand’s power supply—temperature anomalies in electrical contacts (e.g., busbar joints, circuit breaker contacts) pose severe risks. Acrel’s ATE400 wireless temperature monitoring system is tailored to address this core need, ensuring compliance and operational safety.
As Thailand advances its power infrastructure upgrade, substations and distribution rooms demand reliable, real-time temperature monitoring for high-voltage electrical contacts.The ATE400 focuses on precise monitoring of busbar joints, circuit breaker contacts, cable connections, and dry-type transformer terminals—key risk points in electrical facilities—delivering unmatched performance for Thai users.
1. Compliance with IEC international norms
The ATE400 fully complies with IEC international norms, with ±1℃ measurement accuracy and a -50℃ to +125℃ range—ideal for capturing temperature fluctuations in electrical contacts. It provides traceable, real-time data, helping enterprises avoid non-compliance penalties and reduce electrical fire risks, a top concern for Thai power facilities.
2. Stable Operation for Substation/Distribution Room Environments
Adopting CT inductive power supply (starting current ≥5A), the ATE400 boasts a 10+ year service life, eliminating frequent battery replacements in Thailand’s humid, high-temperature electrical facilities. Its 470MHz wireless module ensures stable data transmission (150m open-space distance), penetrating the complex electromagnetic environment of switchgear in substations, guaranteeing uninterrupted monitoring of critical contacts.
3. Flexible Installation on Key Electrical Contacts
Designed for 3-35kV high-voltage and 0.4kV low-voltage switchgear, the ATE400 supports bolt-on, magnetic, and strap-on installation—perfect for busbar joints, circuit breaker contacts, and cable connections. Without cumbersome wiring, it simplifies retrofits in existing Thai substations and distribution rooms, cutting installation time and costs by 40%.
4. Real-Time Alarms & Predictive Maintenance
With a 15-second sampling cycle, the ATE400 transmits real-time temperature data to Acrel’s ARTM-Pn devices or centralized monitors, triggering multi-level alarms (relay/SMS/app) for anomalies. By analyzing temperature trends, it enables predictive maintenance of electrical contacts, reducing unplanned downtime and extending equipment lifespan—critical for Thailand’s power infrastructure reliability.
5. Scalable for Power Facility Needs
A single ATC600-C manages 240 sensors simultaneously—adaptable to small distribution rooms or large substations. It integrates with Acrel’s remote platform via RS485/Ethernet, enabling centralized management of multi-site Thai power facilities, aligning with the country’s smart infrastructure trend.
Globally trusted in power grids, the ATE400 has proven its value in Thai substations and distribution rooms, ensuring stable temperature monitoring of electrical contacts to meet regulatory demands and enhance operational safety. As Thailand strengthens its power infrastructure safety, the ATE400 stands as the preferred solution for precise, compliant, and intelligent temperature monitoring of critical electrical contacts.
