Here you will find help and support information for using the: Relay Tripping Curves PRO 2 software.
Relay Tripping Curves-PRO2 is a software that allows calculating the mathematical equations of the characteristic curves of the overcurrent protections according to the different standards of the main manufacturers of protection relays that exist in the market and representing these curves in a chart with a Log-Log scale in a friendly and simple way.
This software is born from the need to have at hand, at the level of engineers, technicians and engineering students, a simple tool when representing the characteristic curves of the settings of the ANSI 50/51 and ANSI 50N/51N functions of the protection relays, since it performs the calculations of all the mathematical equations and with it feeds the data for the graph of the curves, it can also represent the tripping data of a protection equipment and compare it with the setting curve, also make a report of the tests, which includes setting data, trip verification table and include an image of the tests, additionally with this software you can compare the selectivity between two curves and optimize it.
Toolbar: Contains all the buttons necessary for the program to run, and is divided into three groups:
​
Graphic menu buttons: This contains the buttons necessary to graph the curves in the Log-Log Chart, to go from Secondary values ​​to Primary values, to change the scale of the Log-Log Chart, to change the background color of the Log-Log Chart, to perform numerical calculations and to go to the window for calculating the selectivity between two curves.
​
​
​
​
Test menu buttons: These buttons are used to graph the Current/Time points, to delete the graphed trip points, to activate the cursor to watch the Current/Time values ​​along the graphed curve and to go to the window to make a report.
​
​
​
General menu buttons: With these buttons, the basic functions are performed, to save a graphed curve in the Log-Log Chart, to print the graphed curves, to change the language from English to Spanish, to go to the help for this application and to exit the program.
Data module: This is where you enter all the settings data for the ANSI 50/51 or ANSI 50N/51N functions of the protection relay once the manufacturer has been chosen, that is, the data for the ANSI 51 Function: pickup current (Ip), Time Dial (TD) value, the curve standard to be used with its respective curve type is also chosen.
The data for the ANSI 50 function is also entered: instantaneous current (I>) with its time delay (TI>)
The nomenclature of this data will be as shown by the manufacturer on its protection device.
​
Here you also select the number of the relay to which its settings curves will be represented and enter its respective identification.
Manufacturer Data: This MENU contains the options for the protection relay manufacturer to choose from and for which we want to represent the settings and graph its curve. When selecting one of these manufacturers, a mimic will be displayed that simulates the front screen of the protection relay.
​
If you select the SIEMENS option, 3 options will be displayed to choose from: SIPROTEC5, SIPROTEC4 and Reyrolle with their respective mimic of their front.
If you select the ABB option, 2 options will be displayed to choose from: REF Series and DPU2000 with their respective mimic of their front.
Test points: In this menu, the values ​​of fault currents and trip times are entered, such as the current injection values ​​of a test case or the result of an event recorded by the protection relay.
These points are plotted on the inverse curve graphed on the Log-Log Chart, in this way it is checked if the protection equipment acts within the range of the curve. If any point falls within a range of 10% of the curve, this point will be placed in green, but if the point falls above or is less than 10% of the curve, the point will be placed in red.
Vn and Tc data box: in this menu you enter:
.- Values of the current transformer (CT) ratio when working with secondary values.
.- Operating voltage values of the protection equipment and the reference value with which the inverse curves will be plotted on the Log-Log plane (when working with primary values).
.- The equation of the curve is shown, according to the chosen standard
Log-Log Chart: This screen shows the inverse curves of the selected protection relay, after entering the settings data ANSI 50/51 functions and clicking the button:
​
Trip points (fault current and trip time) are also shown, once the data has been entered in the "Test Points" menu and clicking in:
​
A cursor can be displayed on this screen to view the Amps and Time values ​​along the graphed curve. To activate and / or deactivate this cursor, click on the button:
​
The name of the protection relay to which the graphed curves belong is also identified, as well as the reference voltage of the Log-Log Chart in case of working with primary values.
Once we have graphed a curve and if necessary also the test points on the Log-Log Chart, we can make a report by clicking on the button:
