  1. TRAFO TRANSFORMATOR TRANSFORMER

  2. TRAFO/TRANSFORMATOR/TRANSFORMER

  3. TRAFO

  4. POKOK BAHASAN • KONSTRUKSI • PRINSIP KERJA • MACAM-MACAM • WATAK TEGANGAN DAN ARUS • EFISIENSI

  5. KONSTRUKSI • KUMPARAN PRIMER • KUMPARAN SEKUNDER • INTI BESI

  6. PRINSIP KERJA

  7. PRINSIP KERJA

  8. MACAM-MACAM • Trafo audio: pada rangkaian amplifier • Trafo radio: pada rangkaian pemancar • Trafo matching impedans : pada speaker / horn • Trafo daya 1 fase : adaptor, jaringan listrik 1 fase • Trafo daya 3 fase: gardu induk, jaringan listrik 3 fase • Autotrafo: tegangan outputnya variabel • Trafo pengukuran: trafo arus dan trafo tegangan

  9. MACAM-MACAM Auto transformer Trafo 3 fase Trafo 1 fase

  10. WATAK TEGANGAN DAN ARUS • Trafo ideal

  11. Sistem Tenaga Listrik 150 kV INDUSTRI 500 kV 150 kV TRAFO STEP UP 20/500 kV 20 kV BISNIS TRAFO GITET 500/150 kV TRAFO GI 150/20 kV TRAFO DISTRIBUSI 220 V PEMBANGKIT PLTA PLTD PLTP PLTG PLTU PLTGU 220 V SOSIAL RUMAH PUBLIK

  12. EFISIENSI BEBAN output intput Pinput = Vp x Ip Poutput = Vs x Is

  13. CONTOH SOAL Trafo daya sebuah amplifier digunakan untuk menurunkan tegangan dari 220 volt menjadi 30 volt. Arus yang mengalir dari trafo menuju amplifier tersebut 20 ampere. Bila efisiensi trafo 80 %, hitunglah: • Daya input trafo tersebut. • Arus input trafo tersebut.
