Today many Transmission System Operators (TSO) use Independent Pole Circuit Breakers to enhance power system stability and reliability. Each pole can be independently tripped and so the circuit breaker requires three trip coils.
Features & Benefits
PROFILE IP3 is designed specifically for circuit breakers with multiple trip coils such as independent pole and transmission circuit breakers with dual trip coils, provides a unique insight into their true condition. Capturing the vital ‘first trip’ simultaneously on multiple trip coils, combined with powerful analysis algorithms, shows how the breaker would perform in a real-life fault situation.
After a ‘First Trip’ test has been completed, results will be displayed on the PROFILE IP3.
The values of the key parameters, such as Buffer, Acon & Mcon can be individually selected and displayed for each phase.
After tests have been completed they can be saved for subsequent retrieval from the Auxilary menu. A record can be selected and graphed, which displays a Trip / Close profile for each phase.
Up to four test records can be graphed for comparison and analysis. The First Trip / Close profiles on any phase can be compared with subsequent Trip / Close profiles.
