Owning Palette: Utility VIs
Requires: Electrical Power Suite
Calculates the zero crossing indexes for a voltage and/or current waveform. Zero crossing is the instantaneous point at which the voltage or current turns from positive to negative or from negative to positive.
|reset? specifies to restart the calculation process. The default is FALSE. When you run this VI for the first time, the calculation process restarts automatically.|
|waveforms in specifies voltage or current waveforms. Each array element represents one phase and contains samples representing 10-cycle time interval for a 50 Hz power system or 12-cycle time interval for a 60 Hz power system. Voltage waveforms are in volts and current waveforms are in amperes.
|system info in specifies basic configuration of the electrical power system, which you generate from the Initialize System VI.|
|waveforms out returns voltage or current waveforms after zero crossing calculation.
|zero crossings returns zero crossing indexes.|
|samples since the last cross returns the number of samples since the last cross.|
|system info out returns information about the basic configuration of the electrical power system, which you can pass to further analysis.|
|error out contains error information. This output provides standard error out functionality.|
