Product description
Product parameters
Reference standard: DL/T624-1997, JJG1112-2015.
Features:
● Output up to 6-phase voltage 6-phase current, which can be combined to realize conventional 4-phase voltage 3-phase current type, 6-phase voltage type, 6-phase current type, and 12-phase output mode;
● The output part is controlled by DSP, which has fast calculation speed, strong real-time digital signal processing capability, transmission frequency bandwidth and high-resolution D/A conversion. The output waveform has high precision, small distortion and good linearity. It adopts a large number of advanced technologies and precision component materials, and has carried out professional structural design. Therefore, the device is small in size, light in weight, full in function, easy to carry, and can be operated at startup, and the flow test is very convenient;
● It can complete large-scale complex verification work with high degree of automation. It can easily test and scan various protection settings, perform fault playback, store test data in real time, display vector graphics, print reports online, etc.
● It has one independent 110V and 220V dedicated adjustable DC power supply output, which is convenient for on-site inspection and use;
● The new generation ND-1200 tester is equipped with 10-way opening and 8-way opening for easy self-injection test. The input contact is compatible with the 0~250V potential contact, which can be intelligently and automatically recognized.
● Provide a variety of automatic test software modules and GPS synchronization trigger test （optional）.
