 Product Summary
Description:
As industry trends continue to require
higher transformer utilization with reduced
operations and maintenance budgets it is
becoming vital to reliably monitor asset
health in real time. Real time monitoring of
important parameters such as traditional
transformer main tank/LTC/ cooling
systems, partial discharge, dissolved gas
analysis and bushing health may indicate
early warning signs of potential risks to the
electrical network and associated assets.
Early detection of transformer abnormally
may allow for a shorter issue resolution
