After nearly ten years of development, the functions of electric power testing instruments have gradually changed from simple and low-end to intelligent, miniaturization, networking and diversification. Precision, performance stability, communication means and protocol openness are also further improved. The development and popularization of intelligent power detection instruments and meters, relying on the energy management of intelligent power meters, Internet of things, smart grid and other applications have become the focus of future development, and will drive the sustained and rapid development of intelligent power detection instruments and meters. At the same time, with the development of computer technology, power monitoring instruments have been applied to the power system, transmission, change, distribution, use, scheduling links, to achieve the measurement of grid parameters, measurement, analysis, diagnosis, control, protection, and with analog output and standard communication interface. As a new industry, electric power monitoring instrument has become the information "sensor" of each power grid link, which makes the electrical equipment information "connected" under the smart grid ". Therefore, the power monitoring instrument will also gradually expand the market capacity with the popularity of intelligent distribution at the user end. Among them, the advantages of power meters, analog screens, nuclear radiation detectors, multi-function, high-precision, multi-rate, automatic meter reading and other products are highlighted, and they have gradually become the mainstream of the development of electric energy meters. In the next few years, this trend Will be more obvious.

Electric power testing instrumentation is a wide range of applications in the industry, because of its special status, the role of the national economy has played a huge multiplier and pull. Therefore, it has good market demand and great development potential. Although there is a big gap between China's electric power testing instrument market and foreign countries, it has never stopped developing, especially in the past ten years of construction and development. China's electric power testing instrument has initially formed an industrial system with relatively complete product categories and a certain production scale and development capacity.

Talk about the principle and function of variable frequency series resonant voltage withstand test equipment

Variable frequency series resonant withstand voltage test equipment is mainly used for AC withstand voltage test of cross-linked cable, hydraulic generator, main transformer, bus, GIS and so on. It is composed of variable frequency control power supply, excitation transformer, reactor, capacitor voltage divider and compensation capacitor. Because the voltage, waveform and frequency and the electric field state inside the insulation of the tested object are consistent with the actual operation, and the test voltage is higher than the actual operation voltage, therefore, the insulation strength is strict, direct and effective method.

Overview of Operation Test of Electrical High Voltage Test Equipment

In addition to the long-term operation under rated voltage, the power generation, supply and consumption equipment in the power system must have the insulation strength under overvoltage. Overvoltage refers to the voltage rise that exceeds the normal operating voltage, which is the damage of electrical equipment or protective equipment. In all kinds of power system accidents, a large part is caused by the insulation damage of equipment caused by overvoltage. When the insulation is defective, if it is not found and eliminated in time, it will eventually lead to equipment damage and power failure.

Characteristics of gas-filled test transformer

The inflatable test transformer is a brand-new test equipment, which adopts the characteristics of GIS combination cabinet, with small quality, light volume and beautiful appearance. Its technical indicators have reached the standard requirements, high insulation strength, compressive strength for the same pressure of nitrogen 2.5 times, 2.5 times the breakdown voltage of air. It is equal to the breakdown voltage of oil at 0.25MPa and twice the breakdown voltage of oil at 0.45MPa.
