Simulator is a tool or means that is needed in learning to replace the role of a real system or equipment. The simulator providing a solution for repetitive operation of equipment. This is not possible on the actual equipment such as in a high voltage transformer of electrical distribution system. The purpose of this study was to design a simulator of a 150/20 kV transformer bay interlock system using a PLC as a control device and computer monitor as a display (human machine interface). In this simulator there are 15 states to describe the interlock system between the circuit breaker and the disconnecting switch both on the 150 kV side and on the 20 kV side. Interlock system design using state diagram method. PLC Ladder diagrams are written with CX-programmer software and HMI programming using CX-Supervisor software. The validity test of the simulator is done by using event validity techniques. The design results show that the overall interlock system runs as a whole with the percentage of validity is 100 percent or with a validity index 1, so it can be concluded that the simulator of the 150/20 kV transformer bay interlock system can be used as a learning tool to replace the real system.
