Preventive & Diagnostic Solutions

Sensors installed in power equipment collect and analyze facility operation data in real-time to detect anomalies in advance.

They promote the stable operation of grids and the enhancement of power quality by preventing operation interruptions due to unanticipated accidents at major power facilities in advance.

Features and Benefits

We offer specialized solutions based on superior technology.

  • High sensitivity

    • Utilization of high-sensitivity sensors and the most recent RF design technology to ensure excellent measurement sensitivity.

  • High Analytical Reliability

    • It will be available to analyze the cause and the risk with high accuracy through its own AI diagnosis algorithm.
    • Improvement of operational dependability via field-specific optimization by employing additional functions such as noise elimination and location-tracking algorithm.

  • High Stability

    • Securing stability by protecting hardware devices from incoming surge currents in the event of accidents, such as ground faults and lightning strikes, etc. that may occur in the system.

  • Diverse Delivery Performance

    • We have earned a reputation for quality by supplying for over 300 projects in 13 countries.

  • Continuous Product Innovation

    • Based on our expertise as a manufacturer with a cutting-edge R&D center, we continuously develop new products and pursue product innovation.
