Untuk membedakan antar fasa dalam pemasangan pengahantar instalasi Penerangan 3 fasa adalah....
- A.
Ukuran Penghantar
- B.
Menggunakan taspen
- C.
Taspen
- D.
Warna penghantar
- E.
Ukuran Pipa
Correct Answer
D. Warna penghantarExplanation
The correct answer is "Warna penghantar." In the installation of 3-phase lighting conductors, the differentiation between phases is done by using different colors for each conductor. This helps to identify and distinguish the different phases easily. The size of the conductor, the use of taspen, and the size of the pipe may also be important factors in the installation process, but they are not specifically mentioned in the question.Rate this question:

Correct Answer
A. Panel Hubung BagiExplanation
To avoid interference with lighting installations, the power installation must be separated. This separation starts from the Panel Hubung Bagi, which is a distribution panel that divides the power supply to different circuits. By separating the power installation, any issues or disruptions in the lighting installations can be isolated and addressed without affecting the rest of the power supply.Rate this question:

- D.
Fasa R untuk lantai 1, fasa S untuk lantai 2 dan fasa T untuk lantai 3
- E.
Yang digunakan 2 fasa saja, yang lainya untuk cadangan.
Correct Answer
C. Beban antar fasa dibuat seimbangExplanation
The correct answer states that "Beban antar fasa dibuat seimbang" which means that the load between phases is balanced. This is important in a 3-phase lighting installation for an industrial building with multiple floors. Balancing the load between phases ensures that the electrical system operates efficiently and prevents overloading of any single phase. It also helps to distribute the load evenly across the three phases, reducing the risk of voltage fluctuations and improving the overall stability of the electrical system.Rate this question:

Apabila tegangan 220 volt, cos j 0,9, berapa besarnya daya dan arus fasa 1 pada bagan disamping ini...
- A.
250 watt dan 1,26 Ampere
- B.
340 watt dan 1,26 Ampere
- C.
540 watt dan 3,74 Ampere
- D.
640 watt dan 3,74 Ampere
- E.
740 watt dan 3,74 Ampere
Correct Answer
E. 740 watt dan 3,74 AmpereExplanation
The correct answer is 740 watt dan 3,74 Ampere. This is because power (P) is calculated by multiplying voltage (V) with current (I) and power factor (cos j). In this case, the given voltage is 220 volts, the power factor is 0.9, and the current is unknown. By rearranging the formula, we can calculate the current as I = P / (V * cos j). Plugging in the given values, we get I = 740 / (220 * 0.9) = 3.74 Ampere. Therefore, the power and current for phase 1 are 740 watt and 3.74 Ampere, respectively.Rate this question:

Ruang tamu mempunyai data sebagai berikut:
- Panjang : 3,5 meter
- Lebar : 3 meter
- Lampu PL-C 26 W : 1800 lumen
- Efisiensi 80 % : 0,8
- Intensitas penerangan ruang tamu menurut tabel (E) = 250 lux
- A.
1 buah
- B.
2 buah
- C.
3 buah
- D.
4 buah
- E.
5 buah
Correct Answer
B. 2 buahExplanation
Based on the given data, the room has a length of 3.5 meters and a width of 3 meters. The lamp used is a PL-C 26 W lamp with an efficiency of 80%. The intensity of the illumination in the living room according to the table is 250 lux. To calculate the number of lamps needed, we can use the formula:
Number of lamps = (Illuminance x Area) / (Lamp Lumen x Efficiency)
Plugging in the values, we get:
Number of lamps = (250 lux x 3.5 m x 3 m) / (1800 lumen x 0.8)
Simplifying this equation gives us approximately 2 lamps, which is the correct answer.Rate this question:

- B.
208,33 lux
- C.
209,33 lux
- D.
242 lux
- E.
210,33 lux
Correct Answer
B. 208,33 luxExplanation
The intensity of illumination in a room is calculated by dividing the luminous flux (in lumens) by the product of the room's length and width (in meters squared). In this case, the luminous flux is given as 5000 and the efficiency is given as 86%. Therefore, the actual luminous flux is 5000 * 0.86 = 4300 lumens. The room's length is 6 meters and the width is 4 meters. So, the intensity of illumination is 4300 / (6 * 4) = 208.33 lux.Rate this question:
