Among various algorithms used to diagnose electrical disturbances, the transient detection is considered one of the most important functions. The objective of this paper is to present the Park's transformation (Tdq0) as a simple and efficient tool to detect transients in EHV transmission lines. The evaluation of such technique is performed with actual records from a Brazilian power system utility...
This paper presents the mechanical effect on transformers when subjected to one of the power quality indicators, i.e., the electromagnetic transients. A common reason for internal faults in transformers windings is the weak insulation. This effect can be caused and accelerated by the electromechanical efforts produced by the inrush and short-circuit currents. Even though the transformer energizing...
