  • 2. 

    Pengontrolan suatu instalasi tenaga yang secara utuh dilakukan dengan tangan dan dengan peralatan sederhana disebut .....

    • Manual control

    • Magnetis control

    • Perencanaan

    • Semi otomatis control

    • Manual magnetis control

    Correct Answer
    A. Manual control
    Explanation
    The correct answer is manual control. This refers to the process of controlling a power installation entirely by hand and using simple equipment. It does not involve any automation or advanced technology.

    Rate this question:

  • 3. 

    Rangkaian instalasi tenaga yang pengoperaiannya menggunakan kontraktor magnet dan push bottom termasuk jenis pengendalian ...

    • Manual control

    • Magnetis control

    • Perencanaan

    • Semi otomatis control

    • Manual magnetis control

    Correct Answer
    A. Semi otomatis control
    Explanation
    The given correct answer for this question is "semi otomatis control". This is because the question states that the power installation circuit operates using a magnetic contractor and push button. These components are commonly used in a semi-automatic control system, where the operator has some control over the operation of the circuit through the push button, but the magnetic contractor also plays a role in controlling the flow of electricity. Therefore, the correct answer is "semi otomatis control".

    Rate this question:

  • 4. 

    Suatu saklar yang bekerja berdasarkan kemagnetan lintrik adalah ....

    • Push button

    • Kontaktor magnet

    • Limit switch

    • Float switch

    • TPDT

    Correct Answer
    A. Kontaktor magnet
    Explanation
    A switch that operates based on electromagnetic force is called a magnet contactor. It is used to control the flow of electricity in an electrical circuit by using a magnetic coil to open or close the contacts. This type of switch is commonly used in industrial applications to control large electrical loads.

    Rate this question:

  • 5. 

    Pengertian dari “interlocking” pada rangkaian instalasi motor listrik adalah ... .

    • Dua motor yang bekerja bersama

    • Dua motor bekerja berurutan

    • Sebuah motor dikendalikan dari beberapa tempat

    • Motor bekerja secara otomatis

    • Dua motor bekerja bergantian

    Correct Answer
    A. Dua motor bekerja bergantian
    Explanation
    The term "interlocking" in the context of electrical motor installations refers to two motors working alternately or in sequence. This means that both motors take turns operating, rather than operating simultaneously or independently.

    Rate this question:

  • 6. 

    HC pada magnetik kontaktor berfungsi untuk ... .

    • Menahan kemagnetan

    • Penghubung sumber – motor

    • Mengunci kontaktor lain

    • Pembalik putaran

    • Pembangkit kemagnetan

    Correct Answer
    A. Pembangkit kemagnetan
    Explanation
    HC pada magnetik kontaktor berfungsi untuk pembangkit kemagnetan.

    Rate this question:

  • 7. 

    Cincin hubung singkat pada magnetik kontaktor berfungsi untuk ... .

    • Agar kontaktor tidak bergetar

    • Menahan kontak

    • Menghasilkan arus searah

    • Membalik ggl induksi

    • Mengikat inti besi

    Correct Answer
    A. Agar kontaktor tidak bergetar
    Explanation
    The short-circuit ring on the magnetic contactor functions to prevent the contactor from vibrating. When an electrical current passes through the contactor, it creates a magnetic field that causes the contactor to vibrate. The short-circuit ring helps to stabilize the contactor and prevent this vibration, ensuring that the contactor remains in a stable position and operates effectively.

    Rate this question:

  • 8. 

    Kontaktor type SN 21, mempunyai ....

    • 1 HC, 3 NO, 1 NC

    • 2 HC, 4 NO, 2 NC

    • 2 HC, 5 NO, 1 NC

    • 1 HC, 5 NO, 1 NC

    • 1 HC, 5 NO, 2 NC

    Correct Answer
    A. 1 HC, 5 NO, 2 NC
    Explanation
    The correct answer is 1 HC, 5 NO, 2 NC. This means that the Kontaktor type SN 21 has 1 normally closed (NC) contact, 5 normally open (NO) contacts, and 2 holding coils (HC).

    Rate this question:

  • 9. 

    Fungsi NO (13 – 14) pada magnetik kontaktor berfungsi untuk ... .

    • Mengalirkan arus utama

    • Menghubungkan sumber ke beban

    • Mengalirkan arus lampu tanda

    • Mengalirkan arus lampu start

    • Mengunci kemagnetan HC

    Correct Answer
    A. Mengunci kemagnetan HC
    Explanation
    The function of NO (13-14) in a magnetic contactor is to lock the magnetism of HC.

    Rate this question:

  • 10. 

    Fungsi NC (21 – 22) pada kontaktor magnet dengan lampu-lampu tanda adalah ....

    • Mengalirkan arus utama

    • Menghubungkan sumber ke beban

    • Mengalirkan arus lampu tanda

    • Mengalirkan arus lampu start

    • Mengunci kemagnetan HC

    Correct Answer
    A. Mengalirkan arus lampu tanda
    Explanation
    The function of NC (21-22) in a magnetic contactor with indicator lights is to allow the flow of current to the indicator lights.
