Introduction
The electric power system that generally consists of a channel and load generator is a system that processes the empowerment and use of electrical energy.The need for electrical energy is a primary priority in supporting development activities in various aspects of life [1].So Conducted several studies and studies that are analyzed to improve reliability in the process of empowerment and use of electrical energy.In operation, the power system can not be separated from interference, be it interference that is temporary or permanent disturbance. Interference in the power system consists of symmetrical disruption, asymmetric interference and open conductor disruption [2]. The complex power system implies that the system has multiple machines in the service of the load, so special handling is required in providing customer service continuity by maintaining, effectively handling disturbance conditions so that the distribution of electrical energy does not experience significant constraints .From this it is necessary to conduct a series of analysis of electric power system, one of which is a brief short-circuit analysis using a practical computer.
The learning model (CBL) is a form of computer-based learning model. Computers are used as a medium / tool to deliver materials and teaching materials in the learning process to be able to attract the attention of learners.The teaching materials to be delivered are developed using a learning development model that can be used to create computer-based learning.In the teaching materials, it has included material, questions, and feedback or tasks presented in a single program package.CBL learning model is a teaching and learning system that uses computer equipments as a tool of help together with its knowledge base (knowledge base), is the development of integrated information technology ie communication (interactive), audio, video, image appearance Packed with multimedia designations.WithBenefits of using CBL learning model, among others: (A) Able to reduce training costs, (b) Flexibility of time, (c) Flexibility of learning speed, (d) Standardization of learning, (e) Effectiveness of learning, (f) Can store student data, lessons and ongoing learning process [2] .

The Computer Based Learning (CBL) For Short Circuit Analysis.
The design of instructional media designed to produce an interactive learning media for protection system applied to industrial electrical system, In the sample paper has presented plot of relay coordination response curve for industrial system grid system 3 bus By using this package students get simulation experience as well as knowledge about Industrial applications. The created package has been able to complete the course activity and as a teaching tool For lecturers and students. Computing The program is designed to help students avoid the boredom to calculate the industrial security system by replacing the method of calculation with a simulation dish. This approach can provide a very important stimulus in building self-learning concepts for students [3] The simulated model built asks and directs them (the students) to provide space to discuss the results of short-circuit analysis on the outcomes of the project, (3) Report on simulation results in practical practical laboratory-models of their PSP simulation experiments in learning. And observing And measure Tingat motive Studying students from the PSP-based model of computer simulation experiments. Network modeling, power flow and short-circuit current analysis and Over Current Protection (OC) and coordination of protective relays have been presented using computer-assisted software in ETAP. In addition, students can visualize the results of observing domain errors with OC, distance and differential protection in software PSCAD / EMTDC. Protection for transformer equipment from Over Current (OC), simulation Over voltage and phase imbalance for induction motor device protection have been tested in practical experiment learning with the help of LabVolt electrical module.
