The invention discloses a novel insulating live detection device based on an intelligent sensor technology and relates to the field of live detection. The novel insulating live detection device comprises a processor module, a current transformer, a first signal conditioning and transmitting module, a voltage transformer and a second signal conditioning and transmitting module. The input end of the first signal conditioning and transmitting module is connected with the current transformer, and the input end of the second signal conditioning and transmitting module is connected with the voltage transformer. The output end of the first signal conditioning and transmitting module is connected with the third input end of the processor module, and the output end of the second signal conditioning and transmitting module is connected with the fourth input end of the processor module. The fifth input end of the processor module is connected with a temperature and humidity detecting module. The coupling problem of flux weakening signals in a strong electromagnetic interference environment is solved, and signal distortion is decreased. In addition, temperature compensation and humidity compensation are achieved through an environmental monitoring function in a sensor, the long-term troubled shortcoming that the detected data consistency of the live detection device is poor due to temperature drifts of components and parts is overcome.
