Circuit For Protection Against Slow Circuit Breaker Closure During Synchronization Of A Generator And An Associated Electrical System
US Patent:
6324039, Nov 27, 2001
Filed:
Oct 15, 1997
Appl. No.:
8/950970
Inventors:
Lawrence C. Gross - Pullman WA
Assignee:
Schweitzer Engineering Laboratories, Inc.
International Classification:
H02H 706
US Classification:
361 86
Abstract:
The protecting apparatus includes a circuit for automatically and continuously determining the difference voltage between the voltage at the input side of a connecting circuit breaker and the voltage at an output side thereof between an electric generator and an associated power system, following initiation of closure of the connecting circuit breaker. The difference voltage is representative of the voltage angle of the generator relative to the electrical system. The difference voltage is compared against a reference value, which is selected such that a voltage angle value greater than the reference value will result in damage to the generator and/or the electrical system. An output signal is developed which can then be used to trip circuit breakers serving the electrical system if the reference value is exceeded by the difference voltage.
Stand-Alone Device For Determining Communication Parameters And Channel Configuration Of An Asynchronous Serial Channel Using A User Determined Methodology
US Patent:
2005020, Sep 22, 2005
Filed:
Mar 17, 2004
Appl. No.:
10/803019
Inventors:
Lawrence Gross - Pullman WA, US
David Bogut - Pullman WA, US
David Bogut - Pullman WA, US
International Classification:
H04L012/16
US Classification:
370260000
Abstract:
A computer program controlled microprocessor enables the user to create scripts which are used as input to asynchronous serial devices to prompt the serial device to transmit communication parameters to DTE and DCE drivers which communicate via UART and pulse width detectors with the microprocessor allowing determination and display of communication parameters including Baud Rate and other such communication parameters.
