Product Description

KDJB-803 Three phase relay protection tester

Product Introduction

KDJB-803 three-phase relay protection tester meets all field test requirements. This instrument has a standard four-phase voltage, three-phase current output, voltage 125V/ phase, current 40A/ phase. Three-phase parallel up to 120A. Both the traditional relay and protection devices can be tested, but also a variety of modern computer protection tests, especially for transformer differential power protection and self-throwing devices, the test is more convenient and perfect.

Product Characteristics

1, the standard 4-phase voltage and 3-phase current output has a 4-phase voltage and 3-phase current output, which can be easily carried out a variety of combined outputs for various types of protection tests. Each phase voltage can output 120V, current three and can output 120A, the fourth phase voltage Ux is a multi-function voltage item, can be set to 4 kinds of 3U0 or detection voltage, or any voltage value of the case output.

2, the single machine is easy to operate by the convenient and flexible photoelectric trackball mouse through the large screen LCD display, all Chinese display. It can complete most of the field test and verification work, can verify all kinds of relays and microcomputer protection, and can simulate all kinds of complex transient, permanent and transformational faults for whole group tests. Boot can be used, easy to operate.

3, double operation mode, connect the computer to run through the full set of Chinese operating software on the Windows platform, can carry out a variety of large complex and more automated verification work, can easily test and scan a variety of protection set values, can store test data in real time, display vector graphics, draw fault waveform, online printing reports, etc.

4, powerful software can complete a variety of large and complex calibration work with high degree of automation, such as three-phase differential test, plant power quick cutting, ready self-feeding test, line protection inspection reclossing, etc., can easily test and scan a variety of protection set values, fault playback, real-time storage of test data, display vector diagram, online print reports.

5, the switch quantity contact rich 10 contact input and 8 air contact output. Input contacts are null contacts and 0 ~ 250V potential contacts compatible, intelligent automatic recognition. Input and output contacts can be expanded according to user needs.

6, large screen TFT display This machine adopts 640×480 dot matrix large screen TFT high resolution true color LCD, all operation process are set on the display, the operation interface and test results are displayed in Chinese, the display is intuitive and clear.

7, self-protection using a reasonable design of heat dissipation structure, and has a variety of reliable and perfect protection measures and power soft start, and a certain fault self-diagnosis and blocking function.

8, with an independent dedicated DC power output device with a 110V and 220V dedicated DC power output.

9, cost-effective belongs to the cross-professional joint design products, comprehensive multi-professional advanced scientific and technological achievements. Both the performance of a large tester, and the price of a small tester, with a high performance-to-price ratio.
