In the past, DC withstand voltage tests were widely used for on-site insulation testing of cables and rotating electrical machines, valued for their compact size and low power requirements for capacitive test samples. However, over two decades of global field practice and industry research have show Read More

Shunt reactors are critical reactive‑power compensation assets for high‑voltage transmission networks. They stabilize system voltage, absorb excess capacitive reactive power from long lines, and maintain grid operating quality. However, hidden mechanical and electrical defects such as inter‑turn sho Read More

Transformers are the most valuable and critical equipment assets within a power grid. An unplanned outage of a large power transformer can trigger a cascading power grid disruption, resulting in millions of dollars in direct and indirect economic losses.Traditional diagnostic systems relying on insu Read More
