The invention relates to a VFTO (Very Fast Transient Overvoltage) filter suitable for a GIS (Gas Insulated Switchgear) body type digital collecting device, belonging to the power electronic technical field. Two groups of N-turn coils are symmetrically wound on a same magnetic core. An internal resistor Rs11 and an inductor Ls11 of each turn of coil connected in parallel are grounded through a stray capacitor Cp11. An internal resistor Rs11' and an inductor Ls11' of the coil symmetrical to the coil connected in parallel are grounded through a stray capacitor Cp11'. The N turns of coils are connected in series. The filter has the advantages that the VFTO filter based on theoretical calculation and distributed capacitance conversion technology is provided for effectively avoiding the problem that the high-frequency performance of a low-pass filter is remarkably decreased due to parasitic parameters. The electromagnetic noise degeneration amplitude over 50dB is ensured at the frequency over 1MHz. Meanwhile, a novel passive LC filter which can be directly installed at the front end of a digital circuit of the GIS body type digital collecting device is formed, and has the advantages that the distributed capacitance is utilized, the circuit form is simplified and the cost is lowered.
