Description
Product Overview

The Hertz HZJB-340A is a high-precision three-phase protection relay tester designed for substation applications. It is capable of testing various traditional relays and relay protection devices as well as modern microcomputer protection devices. It is particularly convenient for testing transformer differential protection and auto-reclosing devices.

The HZJB-340A Microcomputer Relay Protection Tester is a new, compact microcomputer relay protection tester developed by extensively consulting user feedback and summarizing the advantages and disadvantages of similar domestic products. It fully utilizes advanced modern microelectronic technology and devices. This tester can operate independently or be connected to a laptop.

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