Description

Overview

GAOTek Advanced Transformer Frequency Analyzer, 1 MHz Range, FRA based on the measurement of the windings characteristic parameters inside the transformer, the tester using the world’s developed countries sound internal fault frequency response analysis (FRA) method, able to make an accurate internal transformer fault judgment. After the completion of the design and manufacture transformers, coils and its internal structure to be finalized, therefore a transformer coil winding, if the voltage level, method of winding are the same, each coil corresponding parameters (Ci, Li) is determined. Thus, the frequency domain response characteristics of each coil also will determine, among the corresponding three-phase coil has a comparable frequency spectrum.
