PC74HCT20N PC74HCT20N PC74HCT20N on stock Under normal conditions little ground, or zero-sequence, current flows in a line. Thus, the pre- sence of such current is a good-indication a fault has occurred, and the main relaying problem is determining whether the fault is internal. For this reason ground relays can normally be much simpler than the phase relays they complement. Minimum Data Active Time Before Clock Pulse (Data Set-Up Time) ...........
