Last week our VIP customer ordered one set GDGS Transformer Tan Delta IPF Insulation Power Factor Tester from our company. This week we already completed the production and arranged the shipment.GDGS is used to measure tan delta.capacitance,power factor and so on of transformer or other insulation m

The Variable Frequency Series AC Resonant Test System is mainly composed of Variable frequency control power supply, excitation transformer, high voltage reactor, high voltage divider and so on. The Variable Frequency Series AC Resonant Test System uses the principle of series resonance, uses the ex

GDRZ-902 Transformer Sweep Frequency Response SFRA Analyzer can draw the frequency response curve accurately. Then you compare the curves horizontally or vertically to detect the deformation of the transformer.
