Description
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.
