For intelligent switchgear, the opening time shall be the time from the reception of the first message containing the trip command via the interface according to the IEC61850 series (GOOSE message), the circuit-breaker is in the closed position, to the instant when the arcing contacts have separated in all poles.
For intelligent switchgear, the closing time shall be the time from the reception of the first message containing the close command via the interface according to the IEC61850 series (GOOSE message), the circuit-breaker is in the open position, to the instant when the contacts touch in all poles as shown in the figure.
In the case of time measurements, coherence shall be checked between the position indication via the serial interface(see figure) in the secondary system and the real position of the intelligent switchgear.
In this Op/Cl delay time testing, the DANEO 400 Omicron test tool (publish IEC 61850 GOOSE Op/Cl trip command as a timer start signal and monitor the breaker Op/Cl contact signal as a stop signal) is an usual way.
Do you have another way or know any test tool for this testing?
Hi
Thank you for your comment.
DANEO 400 Omicron is a fault recorder for IEC 61850 and conventional signals in high voltage substations.
You can find some other equipment like this as TESLA 4000-SV Recorders or from other brands.
