摘要： A visual monitoring system for an electric power substation includes at least one camera for obtaining the image of various operational indicators in the substation, either within the control house, outdoors or both. The indicators could be the status of various gauges, including current, voltage and temperature gauges, or other structural elements, such as the position of various switches, the level of oil in a transformer sight glass, or whether a transformer fan is running, among others. The image is then enhanced to accentuate the desired features, and the desired data is then image detected. The resulting information is then compared against a standard to determine whether or not the operational status of the indicator is abnormal.

摘要： The angle between the negative sequence and zero sequence currents for a power signal on a transmission line is measured and compared against a plurality of successive angle ranges from 0.degree. to 360.degree.. If the angle is 0.degree..+-.30.degree., an AG fault is indicated and a first section output is produced blocking ground elements BG and CG and phase-to-phase elements AB and CA. An angle of 120.degree..+-.30.degree. indicates a BG fault, resulting in a second output blocking ground elements AG and CG and phase-to-phase elements AB and BC, while a phase angle of 240.degree..+-.30.degree. indicates a CG fault, resulting in a third output blocking ground elements AG and BG and phase-to-phase elements BC and CA. If the phase angle is not covered by the above three primary ranges, then a second stage of comparisons are made, including determining the magnitudes of the phase-to-phase distance elements, and then comparing the phase-to-phase resistance of the lowest of those with the apparent resistance of the one ground element, i.e. AG, BG or CG, associated with the non-primary (secondary) range of angles which includes the measured phase angle. If selected criteria are met, then an output is asserted to block the ground and phase-to-phase elements noted above associated with that ground element.

摘要： The motor relay includes thermal models representing the start and run conditions of a motor. The thermal models are implemented using measured current values and certain known operating parameters available from the manufacturer, specifically full load current, locked rotor thermal time and rated service factor. The thermal model information is compared with threshold thermal model values to determine when an overload condition has been reached.

摘要： The relay includes means for obtaining current and voltage samples on the power transmission line for a particular possible fault type. The current sample is multiplied by the replica impedance of the power transmission line, while the voltage sample is multiplied by a polarizing voltage to provide a first complex expression having a real portion and an imaginary portion. The product of the current sample and the replica impedance is multiplied by the polarizing voltage to produce a second complex expression having a real portion and an imaginary portion. The real portion of the first complex expression is then divided by the real portion of the second complex expression to produce a scale value m which is compared against known reference scale values for each zone, so as to determine underimpedance conditions in any one of the zones.

摘要： In a protective relay (10), which contains a microprocessor (30), for monitoring a power transmission line, an output enable decoder (72) and a one-shot timer (74) produce a very short (5 microsecond) signal in response to an address signal from the microprocessor. The output from the timer is applied as one input to AND gate (70). A conventional address decoder, responsive to an address signal identifying a particular output port from the microprocessor, provides another output to AND gate (70). AND gate (70) produces a latch control signal when the two signals are coincident in time. The latch control signal enables the particular output port to receive instructions from a data bus (60).
