Kpm, Sfra, Ia a specialised equipment based on two methods to detect the deformation of the transformer concurrently with time. One is the sweep frequency response analysis method, The other is low, Voltage short, Circuit impedance method. Using two methods can effectively reduce incorrect judgments. The tester is Well-suited for utilization for iec60076, 18, 2012 and iec60076, 5, 2006. Features 1. Using the advanced technical of dds, 2. Using the rapid pace and advanced microprocessor to design, 3. Using ad chip of 16 bits, 4. With seven inch lcd touch screen of which the brightness can function as adjusted, 5. Equipped with a heat-based printing device of which the print thick is capable of being modified, 6. It could store one hundred and twenty groups of fra data, Fifty groups of sci data and thirty groups of which could, Sci data be read to current screen or upload to the pc, 7. With pc software using which we could upload data, Test, Print data, Or create analyze data, Word document, 8.
