LEM Electronics, the leader of global power sensor and the expert of power measurement solutions, has made its appearance at the EP Shanghai 2020 from December 3 to 5. The exhibition was held in Shanghai New International Expo Center.
With the theme of New Infrastructure, New Technology and New Opportunities, the exhibition gathered a lot of power and electrical equipment enterprises and professional visitors, providing a diversified and rich industrial exchange platform for people in the power industry.
In this exhibition, LEM Electronics revealed many new products, such as Rogowski coil in ART series and ARU series, several supporting integrators, ATO series open-ended mutual inductor and HMSR series current sensor, which have won the favor of many customers. It was highly recognized by its flexible structure of the product design and its application advantages in the power industry.

A set of Rogowski coil solution simulation system on display has become the highlight of this exhibition, attracting many professionals onsite. This system simulates the field application of ART. The whole system consists of primary circuit, Rogowski coil, integrator and display instrument. The primary current of 30A is provided by industrial power supply, and then the current is sampled by Rogowski coil. The 4-20mA standard signal output by the integrator is converted into the actual current value by the instrument at the back end and displayed on the instrument panel. The overall system accuracy can be achieved to 5%.
LEM Electronics has been adhering to “Green, Energy-saving and Efficiency” as the brand concept and has provided customers with innovative technology and high-quality power measurement solutions. The products and solutions displayed by LEM Electronics in this exhibition are also designed by combining with its own R&D advantages, constantly innovating and optimizing, which helped customers solve practical problems and improve efficiency.
