Title: Transformer protecting device
Inventor: SASAKI HIROSHI
IPC: H02H7/04
Filed: 1978-05-24
Abstract: PURPOSE: To improve sensitivity and to prevent malfunction by taking out two elements of ratio differential and higher harmonic ratio separately for protecting a transformer when tripping is permitted by both decisions on the basis of respective elements.  
     CONSTITUTION: The abnormal current in a transformer T is detected by current transformers CT 1  and CT 2  to be added to a scalar sum arithmetic circuit 1 and a vector sum arithmetic circuit 2, and the resultant outputs are respectively supplied to a ratio differential element 3 and a higher harmonic ratio element 4 and a higher harmonic ratio element 4. Agreed conditions between both signals are taken by an AND circuit 5 to be used for a trip instruction signal. Level decision circuits L 1  and L 2  are added to a fundamental harmonic detecting circuit F 1  and the second higher harmonic detecting circuit F 2  not to give any blind area to the higher harmonic ratio element 4. Since this construction serves to eliminate the interference between the ratio differential characteristic and the restraining characteristic at the switch-on time of the transformer, both characteristics can be highly promoted in their sensitivity and the system is prevented from malfunctions.

Abstract: PURPOSE:To improve the conpressibility of picture data without losing the reproducibility of the picture by discriminating a section with a constant density level in the said picture data from the section whose density level is continuously changed, and encoding at every section. CONSTITUTION:An analog picture obtained from a original 1 is converted into a digital value by an A/D converter 2 and the converted output is supplied to a subtractor 1 and a delay circuit 4. The subtractor 3 calculates the absolute value and code of the density level difference between adjacent picture elements and the found absolute value and code are inputted a zero detector 5 and a density changing band encoder 6, respectively. When detecting the density difference ''0'' inputted from the subtractor 3, the detector 5 sends the detected signal to a run length encoder 8 and the encoder 6. The encoder 8 counts up the number of picture elements of a picture data during the detected signal is applied, and outputs a run length code at the time when the detected signal is reduced. The encoder 6 recognizes a division whose density level is continuously changed and generates a density changing band code and a discrimination code. Outputs from the encoders 6 and 8 are sent to a transmission line alternately through a switching circuit 10.
