* 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.
  • Long device operating cycle with minimal technical maintenance and the ability to remotely monitor its status.
