Power quality monitoring device TC-50B

Power quality monitoring device TC-50B

       With the widespread use of power electronic devices, the nonlinear load is increasing, and the harmonic content in the power grid is also rising. Harmonic pollution poses a potential threat to the safety, stability and economic operation of the power system, and has a great impact on the surrounding electrical environment。Such as: consume the reactive power reserve of the power system;Increased power line losses;The additional harmonic loss of the motor is increased，Heat up，Shorten the service life;The measurement of electric energy produces a large error;Causing disruption of important and sensitive automatic control and protection devices，The phenomenon of false movement and refusal to move increased，The reliability deteriorates。

       TC-50B power quality monitoring device is a new generation product of our company，It can monitor and analyze 2 ~ 25 harmonics of base wave of voltage and current of bus and line in power grid in real time，It can give alarm to harmonic overreach，The data is uploaded to the background monitoring system through the RS485 or RS232 communication interface，Meet the user's monitoring requirements for power quality。

       TC-50B power quality monitoring device is widely used in power supply systems of power plants, substations, petroleum, coal, iron and steel, metallurgy, chemical and other large factories and mining enterprises with various voltage levels from 380V to 220kV。

       Advanced industrial-grade central processing unit is adopted, which has the advantages of fast operation speed, stable working state and strong anti-interference performance。

       The device adopts frequency automatic locking technology, when the system frequency changes, the device can still get the correct analysis result。

       Based on the principle of fast Fourier transform, the calculation results are fast and accurate, and the basic wave can be used for daily monitoring of 2-25 harmonic voltages, currents, total harmonic distortion, active power, reactive power, power factor, frequency, unbalance, voltage, current deviation, frequency deviation, etc。

       Man-machine interface is friendly, Chinese character display, simple and intuitive operation。

       The device can record 20 off-limit records。
