Apparatus and Method for Calibrating Voltage Spike Waveforms for Three-Phase Electrical Devices and Systems
Abstract
This patent application discloses an apparatus and method for calibrating three-phase voltage spike waveforms used in testing three-phase electrical devices. The apparatus includes a circuit having a plurality of phase voltage lines and a ground line. Phase voltage outputs and a ground output are provided for connection to a device under test. A selection circuit selects one of the phase voltage lines and provides a synchronization voltage signal based on the other lines. A voltage spike generator is joined to the selection circuit for generating a voltage spike waveform synchronized with the voltage signal. Additional circuitry is joined to the voltage spike generator, the phase voltage lines, and the outputs, which applies the voltage spike waveform across the selected phase voltage line and the ground line.
