    Abstract: The techniques described herein allow a wind turbine generator system to automatically capture voltage waveform data corresponding to a voltage disturbance event. Data corresponding to a period preceding the voltage disturbance event, during the event and a period of time after the event are captured and stored for further analysis. The sampling rate is relatively high compared to the frequency of the power provided by the generators.

    Abstract: A GFCI device which has reverse wiring protection is provided where no power is present at the face terminals even when the device is reverse wired. The device has a pair of movable bridges connected to its terminals. The terminal bridge pair makes contact with the load and face terminals providing power to these terminals when the device is reset. The device also has a reset lockout feature that prevents it from being reset after having been tripped if the circuit interrupting portion of the device is non-operational.

    Abstract: A system and method is provided for monitoring the operating condition of a pump by evaluating fault data encoded in the instantaneous current of the motor driving the pump. The data is converted to a frequency spectrum which is analyzed to create a fault signature having fault attributes relating to various fault conditions associated with the pump. The fault signature is then input to a neural network that operates in conjunction with a preprocessing and post processing module to perform decisions and output those decisions to a user interface. A stand alone module is also provided that includes an adaptive preprocessing module, a one-shot unsupervised neural network and a fuzzy based expert system to provide a decision making module that operates with limited human supervision.

    Abstract: In a load for testing an energy production device, such as a fuel cell, a technique is provided for sensing one or more operational parameters for each of a plurality field effect transistors. Analog and digital feedback are provided to adjust the control signal to the FETs to ensure that each remains within its individual safe operating area. The technique preferably takes all of the various operational parameters into account to determine if any individual FET is approaching the SOA boundary, and prevent that single FET from leaving the SOA while continuing to manage the operation of the entire load.
