How Binary channel supervision works in Arc Protection relay VAMP 321

How can we help you today?

Binary channels are supervised with the test pulses which are sent by binary-out channel (BO) & received by binary-in channel (BI).
Binary-out sends a test pulse in every 137 msec. When binary-in channel doesn't receive a test pulse inside the 500 ms delay, ASF Arc Function Self Supervision is activated.
