Relay Fuse Tester

Given the different functional requirements of grid protection systems, testing capabilities require a higher level of sophisticated testing hardware and software to analyze the operation of the entire protection system (or individual protection components) under "real life" situations. Similar improvements in simplifying the user interface and software control of test instruments are further necessary to meet these expanding test capabilities. Rest assured, no matter how complex, every aspect of relay testing can be easily handled with Weshine®'s comprehensive line of Relay Fuse Tester (VS-JB900 series). Plus, whether you're testing traditional electromechanical relays or modern IEC 61850 networked devices, our rugged products deliver the high power you need while still being portable for practical testing.

Product Description

Weshine® Relay Fuse Tester

Weshine developed the first software-driven protective Weshine® Relay Fuse Tester in 2013, and we continue to offer models ranging from computer control (with a comprehensive and simple built-in touch screen user interface) to portable and laboratory-style hand-operated test fixtures to meet every requirement. A Relay Fuse Tester requirement. Relay testing solutions can be an expensive proposition when software is charged separately, but with Weshine solutions, the software required to test most relays is included in the test set so you won't incur additional costs.

Our rich heritage in manufacturing relays and primary injection test solutions benefits from the company's extensive relay testing experience. This experience also drives the success of our global support system - we're here to help you wherever you are!

1. Meets all the requirement of field tests. Relay Fuse Tester with standard 6 phase voltage, 6 phase current output, voltage 125V/phase, current 30A/phase, 6 phases in parallel can up to 180A. Digital Signal Processor Microcomputer. Not only test the traditional relays and protectors, but also test the modern micro computer relays, special for transformer differential protection and transfer equipment.

2. All technical indicators fully meet the standard DL/T624-1997: Technical condition of the relay computer test device.

3. Classic Windows XP operating interface, friendly man-machine interface, easy and fast to operate; High-performance embedded industrial control computer and 8.4 inch resolution of 800 × 600 TFT true color display which provides rich visual information, includes the current working condition and all kinds of help information.

4. The Windows XP system comes with the restore function; avoid system crashes caused due to illegal shutdown, or malfunction, etc.

5. Equipped with ultra-thin industrial keyboard and optical mouse, complete a variety of operations using keyboard or mouse the same as ordinary PC.

6. The main control board is DSP + FPGA architecture, 16 bit DAC output, generates high - density sine wave 2000 points each circle to fundamental wave, which greatly improves the wave quality and the accuracy of the test instrument.

7. Using high-fidelity linear amplifier. Both to ensure the accuracy of a low current, but also guarantee the stability of the high current.

8. USB directly connect with PC, without any adapter cable, easy to use.

9. Can be connected to a laptop computer (optional). Laptop computers and industrial machines use the same software, no need to re-learn the methods of operation.

10. With a separate DC auxiliary voltage source, output voltage 110V(1A), 220V(0.6A), provides relays or protective devices which require DC power.

11. The software with self calibrating function, which avoid to calibrate accuracy by adjusting relays after open the case, greatly improve the stability of the accuracy.
