Debugging a relay model can be advantageous when having trouble with the model. There are multiple cases where you have to debug a relay model. For example the relay does not trip and you want to find…

For this, you will have to assign the circuit breaker of interest inside of the relay logic block (RelLogdip). Status of each assigned circuit breaker can be accessed by defining "_SWTx" Input Signal.…
Yes, this is possible. For this task, we will have to make changes in the relay model itself. This means we will have to add a second current transformer (CT) device, measurement block and to add…
For this task: 1) Navigate to the relay type of interest inside the data manager. 2) Create a new relay object (ElmRelay) and name it "default". 3) Assign the relay type to this new relay. 4) Once the…
The attached document shows the steps necessary to plot an impedance trajectory in the RX diagram. The steps are the same for RMS and EMT simulations and also explained below: 1. Locate the polarizing…
There are two possible ways: 1) Right click on the asynchronous machine of interest using the right mouse button and choose->Show->Time-overcurrent plot. A new time overcurrent plot will…
In attached example (Detailed Model of a CT) a detailed model of a current transformer is presented. By using the EMT simulation saturation of the current transformer is represented in time domain.…
