Product Description

GDJB-1200A Relay Protection Tester

Product Description

Relay Protection Microcomputer Test Device plays a key role in operating electricity power systems reliably and safely. It is the testing device used in professional field of microcomputer protection, relay protection, excitation measurement, fault recorder.


High-Performance Industrial Control Computer

High performance Industrial control computer is adopted as the controlling computer, by which users can run the windows operating system directly. With 8.5"TFT true color LCD display, tracking ball and optimized keyboard, which can be used without the external mouse and keyboard. USB interface, 10-100M net mouth and serial communication interface are located on the back plate of this tester, by which users can access data, communicate data and upgrade software conveniently.

Digital Signal Processor Microcomputer

High-speed digital controlling processor is adopted as the output core of the tester. 32 bit double precision arithmetic is employed in the software, through which arbitrary high-accuracy waveform of each phase can be produced. Since integrative structure is adopted, the structure of the tester is layed compactly.The distance of data transmission is short with tight structure, which overcomes the problem of fewer points of waveform output due to long datacommunication line and narrow frequency band when using the test controller controlled directly by PC.

D/A Conversion and Low-Pass Filtering

High precision D/A converter is employed for ensuring the precision and linearity of current and voltage in the whole range.

Due to high density of fitting point, fidelity of waveform is high and harmonic component is small, which doesn't have a strict requirement on the low-pass filter. Consequently, it has good characteristics of transient, phase frequency and amplitude frequency, which is easy to perform accurate phase-shifting and harmonic superposition and ensures very high precision even when the frequency is high.

Voltage and Current Amplifier

For phase current and voltage, high performance linear amplifier output mode is used in order to make the current and voltage source to directly output all kinds of waveform from the DC waveform to the waveform including all kinds of frequency components, such as square wave, combined waveform overlapped by each order harmonic, fault transient waveform, etc. In addition, the output waveform is clear and smooth without high-frequency radiated interference with neighboring equipment. It can simulate well all kinds of current and voltage characteristics under the circumstance of short circuit fault.

Digital Input and output

This tester has 10 channels digital input and 8 channels output, please refer to the corresponding instruction to hardware structure of 702/703" Tester.

The switching input circuit is compatible for both the empty contacts and 0-250V electric potential contacts in the input and output circuit. When the electric potential contacts are selected, 0-6V belongs to closed switch and 11-250V belongs to open switch. The switching capacity can test the action time and the action time interval of every phaseswitch's contact conveniently.

Auxiliary DC Power Supply Output for Special Use

A circuit of special adjustable DC power supply output is located on the rear panel, which has 110V and 220V two shifts that can be used as test standby power supply on the spot. We still set a potentiometer for this power supply, it can be adjusted within the range of 80%-110%. Rated current of this power supply is 1.5A, which can be used as DC power supply of protective tester or switch loop supply. If overload or short circuit occurs, corresponding protector tube will be burned out (2A/250V), uses only need to change this protector tube at that time.
