HZJB-340S Three Phase Secondary Current Injection Protection Relay Testing Equipment Microcomputer Control

Product Overview

The HZJB-340S is a microcomputer-controlled three-phase secondary current injection relay protection test instrument. It is widely used in line protection, main transformer differential protection, excitation control, and various other fields.

This instrument features standard four-phase voltage and three-phase current output, capable of testing traditional relays and protection devices as well as modern microcomputer protections. It is especially convenient and ideal for testing transformer differential protection and auto-reclosing devices. It 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.

  • Resists high heat, humidity, and salt spray for tropical island use
  • Runs stably at -40°C, cold-proof and anti-condensation
  • IEC compliant, complete calibration certificates provided
  • Local support: spares, on-site training, and instrument calibration
