Product Description

KVJB-610H Six Phase Relay Protection Tester

Six Phase Relay Protection Tester plays a key role in operating electricity power systems reliably and safely. Type KVJB-610H device has 6 phase voltage and 6 phase current output, suitable for various types of relay protection device test.

Feature

  • Comprehensive Field Test Capabilities:This tester meets all field test requirements with standard 6-phase voltage and 6-phase current output, delivering up to 125V/phase and 30A/phase. When 6 phases are connected in parallel, the current can reach up to 180A. Equipped with a Digital Signal Processor (DSP) microcomputer, it tests both traditional relays and protectors as well as modern microcomputer relays, making it ideal for transformer differential protection and transfer equipment testing.
  • Advanced Control Board:Utilizes a DSP + FPGA architecture with a 16-bit DAC output, generating high-density sine waves with 2000 points per cycle, significantly improving wave quality and instrument accuracy.
  • User-Friendly Interface:Features a high-performance embedded industrial control computer and an 8.4-inch TFT true color display with a resolution of 800 × 600, providing rich visual information, including current working conditions and various help information. The interface is designed for ease of use and fast operation.
  • Reliable System:Features reliable and perfect protection measures and power soft start, with a certain degree of fault self-diagnosis and blocking function.
  • Convenient Input Devices:Comes with an ultra-thin industrial keyboard and an optical mouse, allowing for a variety of operations just like on a regular PC.
  • High-Fidelity Linear Amplifier: Ensures accuracy at low currents and stability at high currents.
  • USB Connectivity:Directly connects to a PC via USB without the need for an adapter cable, simplifying usage.
  • Laptop Compatibility: Can be connected to a laptop computer (optional). The same software is used for both laptop and industrial machines, eliminating the need to learn new operating methods.
  • Dedicated DC Auxiliary Voltage Source:Provides a separate DC auxiliary voltage source with output options of 110V (1A) and 220V (0.6A) to power relays or protective devices requiring DC power.
  • Self-Calibrating Software:Features a self-calibrating function, reducing the need for manual calibration adjustments after opening the case, and greatly enhancing accuracy stability.
