RDJB-802M Protection Relay Test Set
Product features:
1. Flexible combination of voltage and current output
Four phase voltage and three phase current can be outpu. It not only can be compatible with the traditional way of various tests, but also can conveniently carry out differential test of three-phase transformer.
2. Operation mode
The device can run independently, and can also be operated by an external laptop or desktop computer, which is convenient and efficient and stable performance.
3. A new hi-fi linear power amplifier
The output port has always insisted on using the modular linear power amplifier instead of the switching power amplifier, which has the high fidelity and high reliability function and excellent performance. High-mid frequency will not be produced to disturb the test, also ensure the smoothing accuracy of waveform produced by the whole course of the high current to the tiny current is excellent.
4. High performance Mainframe
The output part adopts DSP control, which has fast operation, real-time digital signal processing capability, wide bandwidth and high resolution D/A conversion control. The output waveform has the features of high precision, small distortion and good linearity. With using a large number of advanced technology and precision components and materials and the structure of professional design, the device has the features of small volume, light weight, full function, easy to carry, boot can work, flow test is very convenient.
5. Powerful software function
It can complete all kinds of high automatic validation work which is large and complex. It can also conveniently test and scan protection setting, playback of fault, real-time store test data, display vector, online print report and so on. Besides, six-phase current can facilitate the test of three-phase differential protection.
6. Independent DC power output
An 110V and 220V adjustable DC power is designed to supply output.
7. Complete interface
The device with USB communication port can communicate with the computer and other external devices.
8. Perfect self-protection function
With reasonable design of the heat dissipation structure and the reliable and perfect hardware protection measures, it has the power soft start function and the software of the fault self-diagnosis and the output latch function.
