34 DESIGN OF DIGITAL TRANSIENT RECORDER

Abstract

The use of new advanced engineering tools to perform the daily work of the operators, such as Digital Transient Recorder (DTR) which gives a fast and enough information of any abnormal condition to the monitoring personnel which intern, without doubt enhance the control of the system. This device can use simulated or recorded or online signals in advance passed into a personal computer through an interface circuit and processed in the computer using a special software designed for this purpose and the obtained data can be stored for a long period of time according to the sequence events. This device can be used easily by any operator without special knowledge in power system. The Digital Transient Recorder is designed and tested and the obtained results are acceptable. The used language is VISUAL BAISIC. The recorder records only the abnormal (transient) conditions.
