The HZJB-340S Microcomputer Relay Protection Tester is widely used in line protection, main transformer differential protection, excitation control, and various other fields. It features standard four-phase voltage and three-phase current output, making it capable of testing both traditional relays and protection devices as well as modern microcomputer protections. It is especially convenient and effective for testing transformer differential protection and auto-reclosing devices.
The instrument meets the national standard GB/T 7261-2016 Basic Test Methods for Relay Protection and Safety Automatic Devices and the national standard DL/T624-2010 Technical Conditions for Micro-computer Relay Protection Test Devices.
