Protective devices may have adjustable settings for pickup current or the time delay. You may specify any adjustable data range as either continuous or discrete.
Discrete: A range is discrete if there are a finite number of discrete values to which you can adjust the settings. If you select any range as discrete, you must specify all the possible settings available in the rows in the spreadsheet. For example, if the Tap range of a relay is {0.5, 0.6, 0.8, 1, 1.2, 1.5, 2} then select the data range as “Discrete,” and enter the different tap values in separate rows in the spreadsheet called “Values.” Similarly, if time dial of a relay is discrete, select “Discrete” in the dialog box. All the discrete time dial values must be entered separately in consecutive rows in the spreadsheet for time dial.
Continuous: A range is continuously adjustable if it is divisible by a step value. When adjustments are made the setting is incremented or decremented by a multiple of the step value. When you select any range as continuous, you must also specify the step value. For continuous ranges, it is sufficient to provide only two settings: the minimum and the maximum values in the range. For example, if the pickup of a relay is continuously adjustable from 0.5 to 2 with the smallest increment being 0.01, then enter 0.5 as the minimum, 2 as the maximum, setting type as continuous, and the step value as 0.01. When you enter any data range as continuous, EasyPower calculates the intermediate values for the selected setting by interpolation.
