IPC: H02H3/08
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To prevent the incorrect detection of abnormality of an analog detection circuit during protection relay test by single-phase input, by detecting ON state of a circuit breaker which turns ON/OFF a main circuit system, and monitoring the soundness of the analog detection circuit by monitoring a zero-phase current or a zero-phase voltage during the ON state of the circuit breaker. SOLUTION: In a protection relay 10, an ON/OFF state input terminal 12 is provided for the circuit breaker which turns ON/OFF the main circuit system 1. Then ON state of a circuit breaker to which an input is made from the ON/OFF state input terminal 12 of a circuit breaker is detected by CPU 8 and, if the breaker is ON state, that is, in the state of load operation, then the soundness monitor for the analog detection circuit is executed by the monitoring of zero-phase current or zero-phase voltage. Also, other than ON state of the breaker to which the input is given from the ON/OFF state input terminal 12 of the same breaker is detected by the CPU8, and the soundness monitoring of the analog detection circuit by zero-phase monitor is locked other than ON state, that is, other than load operation.

Filed: 1990-07-11
Abstract: PURPOSE:To improve the processing speed of a processor by sending writing image data information to a video memory buffer to temporary store it and sending the writing image data information from the video memory buffer to a video memory through a common bus. CONSTITUTION:Independently of the access of a device 30 to the video memory 11 or not, a processor 14 sends writing image data information to the video memory 11 through the video memory buffer 13. The buffer 13 temporarily stores the writing image data information sent from the processor 14. When the device 30 does not access the video memory 11, the buffer 13 sends the stored writing image data information to the commun bus to write the information in the video memory 11. Consequently, the processing speed of the processor 14 can be improved without lossing the processing speed of image data.
