坦桑尼亚通信公司（Mobitel）基站

Mobitel began operations in 1994 under the name Mobitel and launched Tanzania’s first cellular service. And it expanded significantly and began pre-paid service under the brand “SIMU POA”and began issuing pre-paid cards under the brand “kadi poa”.Base station of telecommunication are mainly basis of functional units . 

The base station contains equipment for transmitting and receiving signal , antennas ,and equipment for encrypting and decrypting communication with base station controller(BSC), which is interrupted by harmonics. The load voltage often fluctuates by poor power quality caused high frequency harmonic. We decided to install the GreenSine with parallel circuit to compensate harmonic in order to decrease the interference of high frequency harmonic in voltage. As far from operation , Mobitel avoids the power quality caused by harmonic and keep base station work well.
