		abstract={The protection system functions as a safety for the electric power system from disturbances that can cause damage to the electricity distribution equipment, one of which is a 1-phase fault to the ground. The protection system in the distribution
area is Ground Fault Relay (GFR). Debur area is the electricity service area of PT. PLN (Persero) UP3 Bandengan. In this discussion, the working coordination of the ground connection relay time must be selective, to secure the debtor feeder
from disturbances, it is necessary to calculate the short circuit and setting the relay from Circuit Breaker Outgoing Middle Point (CBOMP), Outgoing Feeder and Incoming Feeder. The data obtained by the observation method. From the calculation of the data obtained, the largest single-phase fault current to ground
is 929.50 A and the smallest is 708.47 A.By having a delay time of 0.3 seconds on the Circuit Breaker Outgoing Middle Point (CBOMP), 0.7 seconds for the Outgoing Feeder, and 1.1 seconds for the Incoming Feeder}
