Live detection system for insulators with multiple different voltage grades

The invention discloses a live detection system for insulators with multiple different voltage grades. The live detection system comprises a signal acquisition module used for receiving, amplifying and processing an output signal of an electric field sensor; the data processing and analyzing module is used for processing, analyzing and judging the acquired electric field distribution data so as to determine the insulation condition and the damage condition of the insulator; the data display and alarm module is used for displaying a processed result and giving an alarm; the data storage and management module is used for storing and managing the detected electric field distribution data for subsequent analysis and query; and the system control module is used for controlling and managing the operation of the detection system. The method has the advantages of high sensitivity, non-contact detection, high adaptability, automation, real-time monitoring, large data volume processing, comprehensive analysis and the l
