Ripple.Fault acquiring terminal collection devises the remote signalling Key dithering time per remote signalling all the way, its physical significance be relay tip most
Long shaky time.It is less than the stable state before recovering after Key dithering time, telesignalling dithering when the signal jitter time, is defined as electricity
Magnetic disturbance is influenceed, and shake is filtered out.Markers is recorded when signal is shaken, if the signal elapsed time shakes, stabilization is reached
State, can confirm that signal changes.Generally, it is 5ms~20ms to set the time.Obtained by GOOSE communication modes
When taking primary equipment quantity of state, directly read correlation behavior in communication message and conjugate markers.
Actuating signal, which is obtained, two ways, and a kind of mode is to receive the device tripping operations such as protection, peace control using cable mode
Signal, its acquisition modes are identical with cable remote signalling acquisition modes.A kind of mode is to receive GOOSE trip signals acquisition action displacement
Signal carries out markers processing, it is necessary to receive the time to GOOSE.
During fault acquiring terminal record data, each data point carries high precision collecting markers, fault acquiring terminal
