TWJB-03B Microcomputer Relay Protection Tester

TWJB-03B Microcomputer Relay Protection TesterKey Features:

1. Meet all on-site testing requirements. It can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential protection and backup automatic switching devices, making testing more convenient and efficient. It has a standard four phase voltage and outputs three-phase current simultaneously, with a voltage of 125V/phase and a current of 40A/phase. The parallel connection of three-phase current can reach up to 120A.

2. All technical indicators meet the standards of DL/T624-1997 "Technical Conditions for Microcomputer based Test Devices for Relay Protection" issued by the Ministry of Electric Power.

3. Single machine independent operation, built-in high-performance industrial computer, clock speed 300-600MHz, 512M memory, built-in 4G/CF card, running Windows XP operating system.

4. The domestic industry first adopted imported brushed stainless steel panels, stainless steel keyboards, and touch sensitive mice to overcome the disadvantages of inflexible and easily damaged operation of trackball mice. They also chose an 8.4-inch TFT true color display screen with a resolution of 800 × 600, making single machine operation convenient and durable.

5. The main control board adopts a DSP+FPGA structure and a 16 bit DAC output, which can generate a high-density sine wave of 2000 points per week for the base wave, greatly improving the quality of the waveform and enhancing the accuracy of the tester.

6. The power amplifier adopts high fidelity linear power amplifier, which ensures the accuracy of small current and the stability of large current.

Software installation and driver installation:

1. Software installation

TWJB-03B Microcomputer Relay Protection TesterAt the factory, a software CD is provided, which includes three folders: SETUP.EXE, drivers, and user manual. The industrial computer has already installed the application software and USB driver before leaving the factory, and the accompanying laptop has also installed the above programs. If the user wants to reinstall, they can directly double-click the SETUP.EXE file, follow the prompts, and the program will automatically complete the installation.

2. Driver installation

Insert the USB cable, the computer automatically detects a new USB device, selects the directory for installation, enters browsing, finds the location of the driver program, and clicks OK to perform automatic installation. After installation, a label similar to a USB flash drive will pop up in the lower right corner of the screen. Move the mouse to this location to view detailed information, and the screen will display the words USB FOR DSP, indicating that the driver installation is successful and can be used now. If the industrial computer needs to reinstall the program, you can copy the files on the CD to a USB flash drive, insert the USB flash drive into the USB1 port of the industrial computer, and perform the above installation operation on the USB flash drive.
