The utility model discloses a partial discharge pulse amplitude detection circuitry based on multiple process relates to high -voltage electrical equipment inspection technical field. Partial discharge pulse amplitude detection circuitry based on multiple process includes that high -voltage testing transformer, coupling capacitor, quilt are surveyed high -voltage electrical equipment, pulse current sensor, are kept apart protective film piece, AD conversion module, filtering amplification module, control module, communication module and embedded industrial computer, liquid crystal display, overcome different position, characteristic nature and the transmission influences to detecting discharge pulse of discharging, promoted the degree of accuracy of discernment discharge mode with the position. Realized to coil high band frequency response characteristic and the test system that the limit distributes that the technological problem inconsistent with the degree of actually discharging that has effected a radica
