What Are The Characteristics Of Relay Protection Tester

       After understanding the basic introduction of the relay protection tester in the previous section, GDZX further explains what features the relay protection tester has according to the requirements of the majority of users.

1. High performance host

       The output part is controlled by DSP, which has fast running speed, strong real-time digital signal processing ability, wide transmission band and high-resolution D/A conversion. The output waveform has high precision, small distortion and good linearity. The new technology and precision component materials are adopted, and the specialized structure design is carried out. Therefore, the device has the advantages of small volume, light weight, complete functions, easy to carry, and can work after starting up. The flow test is very convenient.

2. High fidelity linear power amplifier

       The well-designed voltage and current amplifier realizes AC and DC sharing, and the output terminal always adopts high-precision, high fidelity and high reliability modular linear power amplifier with excellent performance. The high precision and high precision of medium frequency current will not be produced in the whole test.

3. Large LCD screen

       Large screen high-resolution graphic liquid crystal display is adopted. All operation process is set on the display screen. The operation interface and test results are displayed in Chinese, which is intuitive and clear.

4. Single machine operation is convenient

       It can complete most of the field test and verification work, and can calibrate various relays and microprocessor-based protection, and simulate all kinds of complex transient, permanent and conversion faults for the whole group of tests. The relay protection tester can be used after starting up, and the operation is convenient and fast.

5. Independent special DC power output

       The device is equipped with a 110V and 220V special adjustable DC power output. It can be used to protect the power supply without setting and adjusting by software.

6. Self protection function

       With reasonable design of heat dissipation structure and reliable and perfect protection measures, it can judge the phenomena of over-current, over-voltage, overload, short-circuit, high temperature and abnormal data at the same time, and has certain fault self diagnosis and locking function.

7. Powerful software

       It can complete all kinds of large-scale and complex verification work with high degree of automation. It can test and scan various protection setting values conveniently, carry out fault playback, store test data in real time, display vector diagram, print report online, etc.

8. The interface is complete

       The panel of the device has its own keyboard and mouse, which can be operated by a single computer or by connecting the keyboard and mouse interface with the keyboard and mouse. It also has two USB ports and RS232 ports, which can communicate with computers and other external devices. The test results can be automatically sorted out and recorded into test reports for reference. The test results can also be directly saved by U-disk and easily transmitted to the external PC for editing and printing.

       There are many types of relay protection tester produced by GDZX, which can meet different needs of customers. The main models are: ZX-702 microcomputer relay protection tester, ZX-802 microcomputer relay protection tester, ZX-1200 microcomputer relay protection tester, ZX-1600 microcomputer relay protection tester, ZX-6000 optical digital relay protection tester, etc.
