What Is Relay Setting Calculation. Relay pick up current= %current setting * ct ratio. By using these we can calculate. For inverse time relays the operating time (s) can be calculated from the equation: Ground fault currents in solidly grounded systems can approach phase fault levels. The trip time of an inverse curve is calculated from the following parameters: Plug setting multiplier & time setting multiplier calculation: The generic inverse definite minimum time (idmt) time current curve calculator will allow you to not only produce curves for standard iec and ieee relay characteristics but will. Plug setting multiplier is nothing but a ratio between the actual fault current in the relay operating coil to pick up current (the relay current setting). Enter the tms, current setting and fault current, then press the calculate button to get the tripping time based on the relay characteristics setting. Selected from the standard set of iec. Α i ⋅β t = k (8.2.1) i > 1 −. Is an adjustable time multiplier.
