Hi everyone, I have got maintenance in one substation and one of the electromechanical relays had a problem so the local guys decided to replace it. The old relay is CTG25 (GEC) and it has two stages Overcurrent, one with IDMT curve, and instantaneous stage. The problem is that measured tripping...
Hello, I have problem with downloading records from REF615, but I think the problem is with the entire series 615. I prepared setting for several device REF615, I upload setting to them without any problem, I tested all settings with injection device, but when I try to see records from...
Hello! I have to program one relay REM543. With displeasure I saw that in the Application library of CAP505 didn't have any configuration template only empty configuration. In my experience with REF54x there are several factory configuration, but for REM relay nothing. It is not a big deal, but...
Hello! I have a lot of problems with the communication between LDCM modules of three end overhead line. The problem is that I lost receive signal from time to time from 100% to 20-30%, and I receive synchronization error. For example for 24 hours I have 10-15 comm fail signals. I use...
