Project Description
Product Features:
Calculation volume: active power, reactive power, frequency, positive sequence, negative sequence, zero sequence, vector sum (difference) and phase angle, etc., and the generated calculation volume is displayed in real time;
The electrical test of the general start-up of the generator: the generator characteristic test can be completed, including the generator no-load test, generator short-circuit test, main excitation no-load, load test, etc.; excitation test, including zero-start boost test and de-excitation test , 10% step test, etc.; concurrent test; other tests required by users.
Using advanced industrial control kernel, combined with embedded operating system, users can easily perform operations such as data storage, backup, analysis, and output.
The portable fault recorder is based on the structure of an industrial portable computer. It uses high-performance DSP, high-precision ADC chip, and embedded operating system as the hardware and software architecture. It integrates data acquisition, processing, transmission, storage, analysis and other functions. All-in-one portable device. It also belongs to digital fault recorder.
The DSP acquisition chip performs data acquisition and calculation, so as to achieve full digital analog signal filtering. The flexible and diverse sampling frequency can be selected by users from 10K/s, 20K/s, 50K/s, and 100K/s, which can be used for transient electrical signals. Waveform recording and analysis.
The portable fault recorder is an intelligent instrument that integrates the functions of fault recorder and generator characteristic test. It is favored by the majority of users due to its small size, strong functions, wide application range, flexible configuration and many other advantages. Practical tools for electric power workers, which will make due contributions to the production and technological progress of the electric power industry.
