<P>PROBLEM TO BE SOLVED: To minutely analyze a system response and a device response by storing a duration from a fixed period before first data save trigger start to a fixed period after the last data save trigger start as continuous data without any interruption in the continuous start of a data save trigger although a protective relay device issues a data save trigger start command at occurrence of relay operation, trip command output, or a device fault, and stores analog data such as current and voltage, an operation state of each relay, an equipment state, and an operation state of a device mounted switch or the like, and signal information of each part of a digital sequence logic in a memory within a device. <P>SOLUTION: The continuous data save trigger can be started, and data is stored in the memory within the device as continuous data save without any interruption from the first data save when a new data save trigger is started during data save. <P>COPYRIGHT: (C)2011,JPO&INPIT |
