  • Learn Intermeter Harmonic Testing for Smart Meters with ITECH
    Smart meter is one of the basic equipment for data collection of smart grid (especially smart distribution grid), which undertakes the tasks of original electric energy data collection, metering and transmission, and is the basis for realizing information integration, analysis and optimization, and information presentation. In addition to the basic power consumption measurement function of the traditional power meter, smart meter can also monitor the power quality and power supply condition in real time, so as to respond to users' complaints timely and accurately and take measures in advance to prevent the occurrence of power quality problems, of which the interharmonic detection is a very important part.

  • One article quickly understands the subdivided golden track in green energy-the test application of energy storage converters
    The demand for energy in countries around the world continues to increase, but due to the unstable nature of renewable energy, solar photovoltaics, wind turbines, and energy storage equipment must be widely installed. This has become an emerging high-tech industry and has been listed by the government as one of the six core strategic industries.

  • Standard Analysis ISO 21498-2 Electrical Performance Test Method for High Voltage Components of New Energy Vehicles
    With the rapid development of electric vehicles, testing of high-voltage components has become increasingly critical. High-voltage components are the core components of electric vehicle power systems, mainly including battery packs, motor controllers, high-voltage cables, etc. These components are directly involved in the storage, conversion and transmission of electrical energy, and are directly related to the performance, safety and overall reliability of the vehicle. Therefore, the testing of high-voltage components of electric vehicles is particularly important. ISO 21498-2 came into being in this context.

  • Test solutions for avionics field
    There is always a contradiction between the power supply system and the power-using equipment: the power-using equipment requires uninterrupted, transient-free, pure sine-wave AC power supply and pulsation-free, transient-free DC power supply; while the power supply system expects the power-using equipment to be a constant load, which should not result in voltage waveform distortion due to the fluctuation of the load. For ordinary small appliances, even if they stop working under the influence of fluctuations in the power supply system, it will not cause too much damage. However, for public transportation such as airplanes and ships, the stability of the electrical system should not be taken lightly.

  • Testing Energy Storage BMS Multi-channel Solution for Efficient Simulation of Cells
    In energy storage systems, the testing and validation of the battery management system (BMS) is a crucial part. To ensure that the BMS can accurately collect voltage and current information and respond correctly under various complex battery states, it becomes especially important to simulate the behavior of the cells and packs. The IT2700 Multi-Channel Source-Load Module System, with its powerful multi-channel serial and parallel capabilities, provides an ideal solution for energy storage BMS testing.

  • Low power consumption test ( nA level)
    With the rapid development of microelectronics technology and the improvement of design level, the integration degree and operation capacity of the chip have increased significantly. This leads to a sharp increase in the power consumption of the chip. Therefore, the low-power design and testing of chips is particularly important. Some of the electronic products in our life, such as IoT devices and portable battery-powered products, must also be tested for low power consumption in order to ensure a longer working condition.

  • How to test the surface resistivity of semiconductor materials
    Many important parameters of electronic devices are closely related to the resistivity and the uniformity of its distribution, such as the reverse saturation current of the diode, the saturation voltage drop of the transistor and the magnification β, etc., which are directly related to the resistivity of silicon single crystal. Therefore, the resistivity test of devices has become an important process in chip processing, and its uniformity control and accurate measurement are directly related to whether power devices with better performance can be manufactured in the future.
