Advanced monitoring of electric power systems such as electrical substations

Smart maintenance technology
for electric substation facilities

Improving production efficiency Improvement of labor productivity
Our partial discharge analysis technology constantly monitors
various power receiving and distribution
facilities to detect signs of failure.
Solution Point
  • Discharge signal analysis enables noise discrimination and estimation of the cause of discharge.
  • The partial discharge analysis technology enables continuous monitoring of various types of switchboards and receiving and distribution facilities.
  • Trend monitoring makes it possible to identify deterioration progress and reflect the result in maintenance plans.
Problems that can be solved
If an insulation breakdown accident occurs in power receiving and distribution facilities, it would have a huge impact on production activities and business continuity,
However, it was difficult to detect the signs of failure through diagnostics, and thus equipment management has typically been done through long-cycle periodic replacement maintenance (TBM, Time Based Maintenance).
Challenges for conventional electric equipment management

Controlling water in powder such as ore
Technology to prevent
the slurrying of bulk materials
This technology prevents the slurrying of ores, etc. that tend to go into a slurry state due to moisture adhesion, by adding chemicals to modify their properties.
Data science
Temperature measurement technology that is less affected by emissivity variations
This technology reduces measurement errors due to the fluctuation of emissivity,which has plagued measurement using conventional radiation thermometers.
Metal oxide film deposition for next-generation solar cells
Electron transport layer deposition technology for organic solar cells

The electron transport layer deposition, which previously took several hours, can now be done in a matter of seconds and reducing deposition costs as well.
Negative electrode material for lithium-ion batteries (LiB)
Technology for suppressing negative electrode material swelling during charge and discharge
(JFE Chemical Corporation)
This technology suppresses the negative electrode swelling during charge and discharge,greatly improving the cycle characteristics of LiB.
Visualize compressed air or gas leaks in piping and flanges
