Short circuit fault phase to ground and phase to phase is one of the problems that may arise in the operation of the power transformer in a Substation. The interference caused by the presence of a short circuit caused a lot of losses, losses on the transmission system of electricity and losses on the part of consumers of electric energy. One way to overcome this disorder is with safety protection relay OCR and GFR that works with the Power Breaker (Circuit Breaker). This research will create a Programming-Based Object (PBO) using the GUI of MATLAB, where programs are designed is one answer to cope with the calculation of the adjustment GFR (Ground Fault Relay) attached on the network, the validation of the programming that is done using armed forces data from the company, which for reasons of privacy mentioned as XYZ. Great protection Setting of the interference 1 phase ground occurs along the feeder can be concluded that the working time of GFR on the side of the outgoing and incoming have a difference of 0.4 seconds, thus the design of programming windows in this study can be used as a reference as setting tms on GFR which is mounted on an equipment of protection of electric power because it has been in accordance with the applicable standards.
