High Voltage Generator PrincipleBode Relay Protection TesterThree-Phase High Current GeneratorOn August 25th, Chengxi Company successfully completed the power transmission for the formal power supply of the 10kV single-power 500kVA user substation at Yibinli Primary School in Nankai District, Tianjin. It is understood that the user of Yibinli Primary School in Nankai District, Tianjin, was originally powered by the low-voltage outgoing line of a 10kV public transformer. With the increase in modern teaching equipment and the capacity of students in the educational area, the 50kW low-voltage residential meter (for urban and rural primary and secondary school electricity use) can no longer meet the normal teaching electricity demand. This capacity expansion changed from low-voltage power supply to high-voltage 10kV 500kVA dedicated box-type substation power supply. To ensure the school opens on time this autumn, Chengxi Company proactively undertook the social responsibility of safeguarding power supply on campus. Automatic Capacitance Current Tester. Chengxi Company strictly followed the service standards for key projects, addressing the school's high-reliability electricity needs, considering the surrounding grid structure and channel paths, comparing multiple plans, and formulating a high-standard power supply plan to ensure supply reliability. Li Yue, the key account manager responsible for this project at Chengxi Company, tracked the entire process, and based on the customer's electricity expectation and project construction cycle, jointly formulated the construction plan for internal and external power projects with the customer, further promoting the connection between the expansion supporting project and the customer's internal power project, and providing advance guidance on the difficulties of distribution engineering construction, Qualifications and Honors. Timely inspections and defect elimination were carried out, solving problems one by one.
