GDRB-Ⅱ Sweep Frequency Response Analyzer

GDRB-Ⅱ Sweep Frequency Response Analyzer

GDRB-Ⅱ Transformer Frequency Response Tester detects transformer winding movements and mechanical failures due to mechanical shock, transportation or short circuits. Detection of these displacements ahead of a dielectric failure can reduce unplanned maintenance costs, and provide the possibility to improve system reliability by preventing outages. Additionally, when damage is discovered, repairs may be targeted to a specific phase winding. GDRB-Ⅱ can detect all level power transformers.
