How one “mystery trip” in a thermal power plant led to a new class of DC control relays. When a Control Box Trips “For No Reason” In 2003, a large thermal power plant ran into a problem no operations team wants to see: the local operation box on a high-voltage bay would trip seemingly at random . No breaker failure, no misoperation recorded—just nuisance trips from the control box, often when nearby bays were being operated. The unit was safe, but the operators were not: ev

“Fast, Stable, Efficient” – What Data Acquisition Really Needs At generator sets and plant switchboards, most engineers want the same three things from an AC transducer: Fast – the measured values must follow real power changes in time. Stable – outputs must remain accurate under strong electromagnetic disturbance and changing loads. Efficient – the device should save space, wiring, and commissioning effort. ODES has upgraded its long-running SET503 AC transducer into a ne
