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

Current transformers and voltage transformers are core components for metering and protection in high-voltage systems of substations and transformer factories. Transformer performance testing is a mandatory item in commissioning tests, periodic preventative maintenance, and routine factory tests. Tr Read More

Relay protection serves as the primary safety barrier for modern substations. When faults including short‑circuits, overloads and ground faults occur on transmission lines, transformers and busbars, protective relays must quickly detect abnormal conditions and issue trip commands to isolate faulty s Read More
