NANAO ELECTRIC Manufacture NAWDA Relay Protection Test Set

NAWDA Relay Protection Test Set

Product characteristics

1. Flexible combination of voltage output and current output

The output voltage and output current can reach six-phase, and also can arbitrary combine with regular four-phase voltage and three-phase current, six phase voltage, six phase current, and 12-phase output mode. It not only compatible with the traditional way of various tests, but also used for three-phase transformer differential test and auxiliary power fast switch over and automatic transfer test easily.

2. Operation

This device can contact the laptop and notebook computer to operate directly, is convenient and stable performance.

3. Newly high-fidelity linear amplifier

The output terminal always adopt modular linear amplifier with high-fidelity and high reliability, not use switching amplifier. Testing on site will not generate medium or high frequency interference, and guaranteed the smooth and precision waveform which from high-current  to small-current.

4.High-performance of host

The output part adopt DSP control, high speed of calculation, powerful real-time digital signal processing capability, widely transmission frequency, controlled high-resolution D / A converter. High precision of output waveform, good linearity distortion. Adopting lots of advanced technology and precision components materials, and with professional structural designed, which make the device small, light, full-functions, easy to carry, boot to use, and the flow testing is very convenient.

5.Powerful software function

It can complete a variety of large and complex calibration task with highly automatization, that can test and scan varies protection value easily, make fault recurrence, real-time storing of test data, display vector and online printing reports. 6-phase can test three-phase differential protection conveniently.

6.Separate and special DC power output

Setting 110V and 220V special adjustable DC power output.

7.Completely interface

The device has a USB interface to communicate with computers and other external devices.

8.Perfect self-protection function

Reasonable thermal structure designs, comprehensive and reliable hardware protection measures, with a power soft-start function and functions of software self-diagnostics and fault output latch.

Power supply: AC110V/115V/120V/127V/220V/230V/240V optional

Input frequency: 50Hz/60Hz optional

Note: The users can select the corresponding power which based on their local supply voltage and frequency, and we will confirm it before the delivery (or inform us that the goods will be used in which country advance)
