1Characteristics and main functions

1）Six phase relay protection testerMeet all on-site testing requirements. This instrument has standard six phase voltage and six phase current output, which can be used to test various traditional relays and protection devices, as well as various modern microcomputer protections, especially for transformer differential power protection and backup automatic switching devices, making testing more convenient.

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) Classic Windows XP operating interface, user-friendly human-machine interface, easy and fast operation; A high-performance embedded industrial control computer and a 10.4-inch resolution 800 × 600 LED true color display screen can provide rich and intuitive information, including the current working status of the device and various help information.

4) The Windows XP system comes with a built-in recovery function to prevent system crashes caused by illegal shutdowns or misoperations.

5) The equipment panel is equipped with an ultra-thin industrial keyboard and optical mouse, which can complete various operations through the keyboard or mouse just like operating a regular PC.

6) 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.

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

8) It uses a USB interface to communicate directly with the PC without any adapter cables, making it convenient to use.

9) Can be connected to a laptop to run. Laptops and industrial computers use the same software, so there is no need to relearn the operating methods.

10) Equipped with an independent dedicated DC auxiliary voltage source output, the output voltages are 110V (1A) and 125V (0.6A) respectively. To be used for relays or protective devices that require DC working power supply.

11）Six phase relay protection testerIt has software self calibration function, which avoids the need to open the chassis and adjust the potentiometer to calibrate accuracy, greatly improving the stability of accuracy.
