Sistem pengaitan ( coupling system) diklasifikasikan menurut pengaitan induktip dan pengaitan kapasitip. Karena jebakan saluran (line trap) merupakan impedansi tinggi terhadap frekuensi pembawa, maka jebakan ini diserikan dengan saluran transmisi tenaga guna memperbaiki karakteristik penyaluran gelombang-gelombang pembawa. Pengaitan induktip lewat udara menggunakan penghantar yang dipasang sejajar dan dengan jarak tertentu dari saluran transmisi; sistem ini dipakai untuk mengaitkan peralatan PLC ...

Komunikasi Gelombang Mikro
Jangkau frekuensi untuk komunikasi dengan gelombang mikro (microwave) adalah 300 – 3000 MHz (dinamakan ultra-high frequency, disingkat UHF) dan 3000 30000 MHz (dinamakan super-high frequency, disingkat SHF).” Frekuensi UHF ke atas dinamakan gelombang mikro, meskipun ada juga yang menggunakan batas 1000 MHz. Frekuensi yang biasanya digunakan oleh perusahaan listrik’adalah frekuensi sekitar (band) 400 MHz, 2000 MHz dan 7000 MHz. Spesifikasi ...

Telecommunications with many radio sets are also used in the electric power industry as shown in Table 6-5. Its use seems to remain will play an important role, particularly because of its superiority in a state of natural disasters (hurricanes, floods) compared to communication via a wire. Specification change the working frequency is used, namely the very high frequency (VHF) ...

Reach frequency for communication with the microwave (microwave) is 300-3000 MHz (called ultra-high frequency, abbreviated UHF) and 3000 30000 MHz (called super-high frequency, abbreviated SHF). “UHF frequencies up called microwaves, though there is also a limit of 1000 MHz. The frequency is typically used by companies around the listrik’adalah frequency (band) 400 MHz, 2000 MHz and 7000 MHz. Specification of ...

There are two kinds of power sources for control in GI, is a source of direct current and alternating current source. Power source to control always have to have a high reliability and stability. Due to this requirement a battery used as a source of direct current. There are two macarn battery (battery): lead and alkali. Now it was Black ...

Linkage system (coupling system) are classified according to the association of inductive and capacitive association. Because the trap line (line trap) is a high impedance to the carrier frequency, then the trap is in series with the power transmission line in order to improve the characteristics of the distribution of the carrier waves. Inductive association through the air using a ...
