Relay Tripping Curves PRO

Those who work in the field of electrical design for power systems might be well aware of the ANSI Standard Device Numbers, as well as the normative framework that is imposed when dealing with phase overcurrent situations, such as in the ANSI 50 protection function. Testing the adjustment curves for such protection relays requires specialized software, such as Relay Tripping Curves PRO.

Built with a standardized layout, which contains brand, relay settings data, test points, as well as a plotting area, the app’s control panel allows one to select a preferred manufacturer, manually input the ANSI 51 or 50 values, select a curve type and preview the plotted data on the graph.

Having selected the required curve and CT ratio, users will then be able to preview the curve equation and a dedicated value calculator will provide numerical inputs for all of the selected amp points on the plotted curve.

One can alter the graph’s scale parameters, by inputting minimum and maximum values for the current and temporal axes. Several, on-screen commands offer quick access to features for cleaning the points on the graph, the curve as well as for generating reports and setting the background color characteristics.
