The invention discloses an automatic feeder testing system free of networking, wherein the automatic feeder testing system is connected with a distribution network which comprises power distribution terminals and protective relays. Each power distribution terminal and each protective relay respectively comprise a remote measurement module, a remote signaling module and a remote control module. The automatic feeder testing system comprises a plurality of automatic feeder testing instruments which are connected with the power distribution terminals or the protective relays respectively, and working stations which are in communication connection with the automatic feeder testing instruments through USBes respectively. The automatic feeder testing system is a testing system which verifies automatic processing logic of the power distribution terminals or the protective relays deployed on site and feeders of the power distribution terminals or the protective relays. No networking is needed during testing, workloads of site test are greatly reduced, whether a deployed power distribution automating system can correctly process various faults or not in the normal state can be tested, and whether the deployed power distribution automating system can process various faults or not under the various interference conditions can be verified.
