Abstract: Disclosed is a simplified electrical power disturbance gage. The gage is capable of measuring high-speed anomalies on power mains. The gage includes elements capable of detecting power line anomalies that effect the operation of electrical devices connected to the power line.

Abstract: An simplified power disturbance gage is provided which can measure and quantify high speed anomalies on the power mains, and which requires no special training and can be used by a service technician in just a few moments to determine which power line anomalies are the cause of failure of connected equipment, without the need for complicated graphs or analysis by experienced technicians or engineering professionals additionally, the gage of the present invention can learn the acceptable limits of operation and report when the power lines deviate from the normally established limits of the power disturbances or the learned limits of the power disturbances.

Abstract: This invention relates to methods of providing uninterruptible, regulated, single phase power to a critical single phase load when such power is derived from two of the phases of a polyphase power source. This invention describes a dual primary ferroresonant transformer which provides regulated and isolated voltage to a single phase critical load, when powered by a plurality of phases from a polyphase power source, and whereby a loss of electrical power to either a first or a second primary does not disturb the single phase power output voltage.

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. An AC line power conditioner utilizing a microprocessor based control system for providing suitable alarms when an operating input AC line is defective or the trend of measured deficiencies predicts line power failure and for initiating an inverter control signal when an inverter module is attached as an option. The software controlled 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 dropouts, measures frequency, and identifies each defect and computes associated trends, stores all accumulated data in a Log Buffer for digital printout, and then provides appropriate alarms to a user.
