Abstract: An intelligent static transfer switch provides a primary voltage source to a destination facility via a primary power supply, monitoring the voltage level associated with the primary power supply. When the primary voltage drops below a threshold level (e.g., conditions normally associated with a transfer to a backup power supply), the switch samples the waveform of the primary voltage and compares the sampled waveform to reference waveforms stored to memory, each reference waveform corresponding to an order to allow or inhibit the transfer to backup power. When the sampled waveform matches a reference waveform, the switch carries out the corresponding order (allow or inhibit). When there is no match, the switch allows transfer to backup power but continues to monitor the sampled waveform to determine whether the transfer should have been allowed or inhibited. The sampled waveform is added as a reference waveform with the appropriate allow or inhibit order.
