  • On-site inspection and design requirements for microcomputer relay protection devices

    ​1. On-site maintenance items of microcomputer relay protection devices include:

  • How to ensure the transportation of DC resistance testers?

    The transformer DC resistance tester is commonly used to measure the DC resistance of large capacity transformers. It is a high-precision stable current power supply and testing part designed as a whole. The testing process is controlled by a microcomputer and automatically completes stable current judgment, data acquisition, data processing, resistance value display and printing. This instrument can complete the longitudinal test of the on load voltage regulator with one power supply, fully saving test time.

  • Development status and trends of integrated substation automation

    The substation is an indispensable and important link in the power system. It is responsible for the heavy tasks of power conversion and power redistribution, and plays a decisive role in the economic operation of the power grid. In order to improve the stable operation level of substations, reduce operation and maintenance costs, improve economic benefits, and provide high-quality electric energy services to users, comprehensive automation technology for substations has begun to emerge and has been widely used.

  • What current is generally selected for a transformer DC resistance tester?

    ​The DC resistance test of transformer windings is an indispensable test item for transformers after handover, overhaul, and change of tap changer. Under normal circumstances, measuring the DC resistance of transformer windings and high-power inductive equipment using traditional methods is a time-consuming and labor-intensive task. To change this situation, shorten measurement time, and reduce the workload of testers, a transformer DC resistance tester can be used.

  • Multiple measurements of power quality

    ​Weshine's independently developed power quality analyzer is a portable product that detects and analyzes the operational quality of the power grid. It can provide harmonic analysis and power quality analysis in power operation, and is equipped with large capacity memory for long-term data collection and detection of power grid operation. At the same time, it is equipped with PC application software to upload the collected data to the computer for various analyses.

  • The difference between current transformers and voltage transformers

    ​1. A transformer that converts high values of current into low values is called a current transformer, while a transformer that converts high values of voltage into low values is called a voltage transformer.
