Multi Phase Voltage Calibration Source , Standard Electrical Test Meter Calibration

1. Function Description

1) High-precision programmable voltage and current output, amplitude, phase and frequency are arbitrarily adjustable
2) Support state sequence output mode, state switching delay is less than 100uS
3) Support the trigger signal, start the output when the trigger pulse arrives, and the trigger delay is less than or equal to 100us
4) Support multiple devices to synchronize output synchronously under the synchronization signal, and use GPS second pulse signal to achieve long-distance synchronization
5) Support recording playback function
6) The multi-phase currents are isolated from each other and can be output in parallel. The total output current is the vector sum of the multi-phase outputs. The total current can be obtained by setting the phase to the same phase.
7) Note: Multi-phase voltages are not isolated and cannot be used in series or in parallel. In severe cases, the equipment will be burnt.

2. Application field

Distribution network terminal test, transformer test, electric energy meter test, etc. where large output power and output current are required

3. Main features of the product

1) It is possible to output a pure sinusoidal power signal with a distortion of 0.05% (typical).
2) The frequency output can be adjusted from 40Hz to 100Hz, the resolution is 0.001Hz, and the accuracy is 0.002Hz.
3) Each phase frequency is individually adjustable, so it can be phase-separated.
4) The phase 0~360 degrees can be adjusted arbitrarily, which can easily simulate various power supply situations and even reverse power transmission.
5) Strong load capacity, full load capacity, inductive, resistive load or composite type load, and the load regulation rate is better than 0.05% RG.
6) Excellent temperature stability, the core device is a military grade product with a temperature coefficient as small as 1PPM, which can guarantee the output precision in the outdoor temperature environment.
7) It is powerful and flexible with 32-bit MCU+DSP processor.
8) The waveform of the power frequency is up to 50,000 points per week, and the internal signal output is smoothed without filters. It ensures the accurate output of the waveform, making the output of higher harmonics possible, and the system has excellent harmonic distortion. Degree indicator.
9) It has RJ45 network port and RS232 port for convenient connection with PC or secondary development.
10) Improve the protection function.
11) Hardware PID, response time is less than 100us.
12) Typical load regulation is less than one in ten thousand.
13) The main control module + expansion module combination structure can be easily combined into a 1~4 phase test system.
14) Multiphase currents can be connected in parallel to obtain a large current output.
15) Provide multi-platform protocol library interface to facilitate secondary development of users. The specific development platform is welcome to call us.

Shenzhen Xinglong Technology Co., Ltd. was established in 2004, is located in the Nanshan District, Shenzhen high tech Industrial Park, is a professional engaged in the Smart Substation detection equipment R & D, production and sales of national key high-tech enterprise (certificate number: GF201244200546). Attention to intelligence (in the field of digital substation testing technology research, from the beginning of 2009 will be gradually introduced various types of testing equipment, including electronic transformer calibrator, digital electric energy meter calibrator (check), with unit testing instrument, and wisdom to substation field testing and acceptance of the project provides the means and tools. Companies actively involved in the development of a number of national standards, to help power companies to solve some of the problems in the field of intelligent substation testing industry technology.

- SYN is a technology started the company, our unremitting pursuit of technology embodied in products of excellent performance, company's substation intelligent test series products has 26 provinces in the country get successful application, and successfully applied to the "China Electric Power Research Institute (EPRI)", "Chinese Academy", "national high voltage metering station" national level institutions.

The company established a complete quality control system and after-sales service system, as of the end of 2014 the company engineering staff has been involved in the testing of more than 100 National Smart substations, for users to solve a lot of technical problems.

Company has won 7 provincial and ministerial science and technology award, the product has laid a good reputation in the industry.

2014 August Xinglong technology successfully in the shares of small and medium-sized enterprises transfer system (the new board) listing (Stock Code: 830924 and become a public company.

Syn can not develop without the support from all sectors of society, we warmly welcome domestic and foreign customers, agents, investors and our sincere cooperation, common development. The future of the company will be with the national system for the transfer of shares in the capital market platform, efforts to technology upgrades and new product research and development, with three to five years to intelligent substation test products to cover all aspects of the smart substation. Strive to become a benchmark for the field of intelligent substation testing business, for the construction and development of China's smart grid to contribute their own diligence and wisdom.
