Abstract:
A software management system of an intelligent power conditioner with backup system option employing trend analysis for early prediction of AC power line failure, utilizing a microprocessor based control system for providing suitable alarms when an operating input AC line is imminently defective and for initiating an inverter control signal when an inverter module is attached as an option, whereby said control system analyzes the input and output voltages, provides analysis of input voltage surges and sags, measures transient amplitude and transient pulse width, counts glitches, and discontinuities or dropouts, measures frequency, and identifies each defect and computes associated trends, stores all accumulated data in a Log Buffer for digital printout and video display, and then provides appropriate alarms to the user advising of imminent power failure and the need for said inverter module, if said inverter module, which can be attached by simple plug in, has not been attached thereto.
