Secondary Current Injection Kit Protection Relay Tester

Core Description

The instrument has standard four phase voltage and three-phase current output (six phase voltage and six phase current output). It can not only test various traditional relays and protection devices, but also test various modern microcomputer protection, especially for transformer differential power protection and standby automatic switching device. The test is more convenient and perfect.

Introduction

1. Classic Windows XP operation interface, friendly man-machine interface, simple and fast operation; High performance embedded industrial control computer and 8.4-inch resolution of 800 × The TFT true color display of 600 can provide rich and intuitive information, including the current working state of the equipment and various help information.
2. The native Windows XP system has its own recovery function to avoid system crash caused by illegal shutdown or misoperation.
3. It is equipped with ultra-thin industrial keyboard and photoelectric mouse, which can complete various operations through keyboard or mouse like ordinary PC.
4. The main control board adopts DSP + FPGA structure and 16 bit DAC output. It can generate 2000 high-density sine waves per week for the fundamental wave, which greatly improves the quality of the waveform and the accuracy of the tester.
5. The power amplifier adopts high fidelity linear power amplifier, which not only ensures the accuracy of small current, but also ensures the stability of large current.
6. It adopts USB interface to communicate directly with PC without any adapter line, which is convenient to use.
7. It can be connected to a laptop (optional) for operation. The notebook computer and industrial computer use the same set of software, and there is no need to learn the operation method again.
8. It has GPS synchronization test function. The device can be equipped with a built-in GPS synchronization card (optional) and connected with PC through RS232 port to realize the synchronous adjustment test of two testers in different places.
9. It is equipped with independent and special DC auxiliary voltage source output, and the output voltage is 110V (1a) and 220V (0.6A) respectively.
It can be used for relays or protective devices requiring DC working power supply.
10.It has the function of software self calibration, which avoids opening the chassis and calibrating the accuracy by adjusting the potentiometer, thus greatly improving the stability of the accuracy.
