Read MoreElectrical system is the basic technical guarantee for high-rise buildings to provide user-friendly services to owners and ensure the stable operation of building automation system. At the same time, in the total energy consumption of high-rise buildings, the electrical system also accounts for a large part of the energy consumption.
Read MoreThe quality of the distribution box is closely related to the transformer of the distribution box, but most people do not understand the transformer of the distribution box, nor do they know what the role of this part is, in fact, the role of the transformer of the distribution box is very large, and relay protection is one of the well-known roles. Through the relay protection can ensure the stability of the current, to ensure that the enterprise does not have any problems in the production process.
Read MoreThe transformer, as an important measuring instrument, is used in the power system, which makes the high voltage and current visible through the transformer. The transformer can measure the voltage, current and electric energy of the primary system in combination with measuring instruments and metering devices. Together with the relay protection and automatic device, it can constitute the electrical protection and automatic control of various faults in the power grid. The performance of transformer directly affects the accuracy of power system measurement and measurement and the reliability of relay protection device.
Read MoreThe current transformer installed at the outlet of the generator can be used as a current signal acquisition device to provide current signals to the generator power meter and realize power statistics.
