As an emerging sub-industry of electrical instrumentation industry, power monitoring instrument belongs to mounted digital instrument, evolving from analog pointer instrument and electricity transmitter. With the development of computer technology, power monitoring instrument has been applied into the transmission, transformation, distribution, usage and other links of power system, enabling to achieve measurement, metering, analysis, diagnosis, control, and protection of electrical parameters on the grid; in addition, power monitoring instrument has analog output and standard communication interface. In face of different applications, the functionality shows different combinations, simple or complex; but it commonly can be divided into three categories: monitoring and protection devices, power analysis and management instrumentation, electrical safety instrument. And its development is mainly related to three factors:
Propulsion of the intelligent demand from power distribution system and of smart grid
Currently, electricity production, transmission and high-end users, such as telecommunications, bank, petrochemical and other large users’ power distribution is achieving information, intelligence. With the advance of smart grid, electricity production, transmission will see information sharing; smart electricity meters will be the information
sensor of various grid links, combining the electrical equipment information under smart grid. As such, power monitoring instrument will gradually expand market capacity with the popularity of intelligent user-end distribution.
The energy-saving of industrial and mining enterprises and buildings
Given the great promotion to energy saving from government policy, high power consumption enterprises should establish energy management system, adopt saving technology and measures to improve the efficiency of energy. Electricity is the major energy; the user-end company with large power consumption should establish electricity metering system. As a result, the smart electricity meters for internal management will increase with the promotion of energy saving policies.
The development demand for new energy and industry
With the development of society, the demand for nuclear power, hydropower, solar energy, wind power and other new energy gradually expand to reduce dependence on non-renewable energy. The development of new energy also brings development opportunity to power meters.
In addition, the protection of the safety of human life also increasingly gains traction. For the safe use of electricity, many countries issued a number of design specification, providing theaters, shopping malls, exhibition halls, hospitals, telecommunications, building, broadcasting stations, high-rise buildings and other personnel-intensive or an important place to install residual-current fire monitoring device, preventing the fire caused by leakage.
At present, the market is basically monopolized by the German Bender; despite the provision asking for installation, power monitoring instrument still can not achieve popularity. However, with the launch of local products, breaking the monopoly, and the resulting price falling as well as the popularity of health, market will further expand. So, power meter also exhibits strong demand in new energy and novel industry.
