Abstract In relay protection testing work, the disassembly and wiring steps of the terminal block signal circuit of the protection device are complex and risky, involving the disassembly and assembly of screws and signal wires, as well as the fixing screws after the pin connection, etc. This not only increases the difficulty of operation but also can easily lead to miswiring, accidental contact of signal lines, and other safety incidents, which may cause the protection devices to malfunction. To improve testing efficiency and ensure the safety of the testing process, this paper designs and develops a Phoenix terminal relay protection test adapter that does not require disassembly and wiring. The adapter aims to simplify the wiring process, reduce the difficulty of operation, effectively avoid safety risks caused by misoperation, and provide a more convenient and safe solution for relay protection testing work.
