Product Introduction
The Six Phase Relay Protection Tester is a new miniaturized microcomputer relay protection tester based on DL/T 624-2023 "Technical Conditions for Microcomputer Relay Protection Test Equipment" issued by the Ministry of Electric Power. It has widely listened to user opinions, summarized the advantages and disadvantages of similar domestic products, and fully utilized modern advanced microelectronics technology and devices. The flexible combination of voltage and current output can reach up to 6-phase voltage and 6-phase current, and can be freely combined to achieve traditional 4-phase voltage, 3-phase current type, 6-phase voltage type, 6-phase and 12-phase output modes. It is not only compatible with various traditional testing methods, but also convenient for differential testing of three-phase transformers and rapid cutting off and preparation of plant power for self injection testing.
