DGA ATHERO S250-2
Next-Generation Stationary System
* The DGA ATHERO S250-2 model can be supplied either with or without a monitor
ATHERO introduces a new generation of DGA monitoring devices with the ATHERO S250-2 – a more advanced version of the S250, offering optimal transformer protection in harsh operating conditions.
The core measurement technology of the stationary DGA device ATHERO remains advanced chromatography, which requires no frequent calibration, carrier gas, or other consumables. This technology delivers high-precision laboratory readings.
Monitoring with the DGA ATHERO S250-2 involves real-time tracking of transformer conditions, including gas levels in oil, moisture, and pressure, with remote access and control features. Sampling intervals start from 30 minutes, ensuring stable performance, eliminating false alarms, and delivering the most reliable long-term measurements for all types of fault gases.
Key Benefits
- Real-time monitoring enables immediate notifications about multi-gas diagnostics and transformer condition deterioration.
- Data can be transmitted to both the device’s internal management system and external enterprise systems, such as SCADA.
- Supports a wide range of communication methods and protocols for seamless integration.
- Early detection of transformer issues ensures preventive maintenance and operational efficiency.

Advantages of ATHERO DGA Monitoring Systems

Durability
ATHERO's DGA systems are built for long-term reliability, even in challenging environments. With superior resistance to external factors, these systems are capable of maintaining stable performance over extended periods, minimizing the need for frequent maintenance or replacement.

Minimal Maintenance
Designed for low-maintenance operation, ATHERO devices require fewer service interventions, ensuring they run smoothly and efficiently over time, with minimal upkeep needed.

No Need for Carrier Gas
In contrast to other systems, ATHERO's DGA technology operates without the need for carrier gas. This eliminates complexities in maintenance, lowers operating expenses, and reduces the risks linked to handling and storing carrier gases.
