Relay Minimum Time Gaps

Option Descriptions

Option	Description
Relay Minimum Time Gaps	The time gap between two protective devices ensures selective coordination. It is dependent on the combination of the devices. The spreadsheet lists different combinations of protective devices consisting of induction disks (ID) and solid state (SS) relays, fuses and LV breakers. The minimum time gap is the sum of the Overtravel, Safety Margin, auxiliary, and breaker opening times.
