THIS CONSIDERATIONS SHOULD BE STRICKLY FOLLOWED: SOUND ENGINEERING AND ACCEPTABLE ECONOMICS; 1.DEFINE DEMAND LOAD - BASED ON ACTUAL SYSTEM VOLTAGE AND PHASE. 2. ONE WAY LENGTH OF CABLE - FT. (AWG) OR MTR. (SQ.MM) SELECTION 3. MULTIPLY BY 125% TO THE CALCULATED LINE CURRENT TO GET AMPACITY REFERENCE 4. LOOK OR SELECT THAT NEAREST RESULT TO ANY LOCAL MEDIUM VOLTAGE CABLE SUPPLIER CATALOGUE OR NEC TABLES AND MATCH IT TO CORRESPONDING CABLE SIZE. 5. APPLY DERATING FACTORS - ALSO AVAILABLE TO NEC OR CABLE SUPPLIERS AND DEFINE THE FF: A. MEDIUM OF INSTALLATION - TRANSMISSION TOWER, PVC OR RSC CONDUIT, CABLE TRAY OR CABLE LADDER OR TRUNKING, THROUGH, ETC. B. AMBIENT TEMPERATURE - INDOOR OR OUTDOOR? C. GROUP FACTOR - CONSIST OF CABLE SPACING AND DISTANCE TO WALL OR INSIDE CONDUIT INSTALLED IN TRAYS OR UNDERGROUND 6. APPLY DERATION IN WHICH RESULT IS LESS THAN ONE (1) TO THE PRE-SELECTED CABLE - THIS IS NOW YOUR ACTUAL FOR SELECTED CABLE 7. DEFINE REQUIRED OR ACCEPTED VOLTAGE DROP IN PERCENT VALUE 8. NOW USE THIS FORMULA: VDapp(APPLICABLE VOLTAGE DROP) = %Voltage Drop x Actual Voltage x 1000 divided by Derated Current x One Way Length x 100 9. THE RESULT WILL HAVE A UNIT OF -- mV/A.Mtr OR MILLIVOLT PER AMPERE-METER 10. NOW COMPARE IT TO AVAILABLE TABLES FOR VOLTAGE DROPS OF CABLES - IF IT IS LOWER THEN SELECT THE NEXT SIZE OR WHICH EVER MEET THE REQUIREMENT.

What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
Whose law state that the induced voltage will produce a current that always act oppose the change that originally caused it?
It is the Micheal Faraday's law of electromagnetism.
What are variable length arrays in C99?
An array whose length is not known in compilation time. int testfun (int n) { int varr [n]; ... } it is ok in C99, invalid in earlier versions.
What is a resistor in electricity?
Resistor is an eletrical and electronical part whose function is to decrease the value of the voltage in a circuit, consequently reducing the value of the current, which is measured in Amperes.
What is direct and alternating voltage?
An alternating current (AC) is an electric current whose direction reverses cyclically, as opposed to direct current, whose direction remains constant. The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy.
How do you calculate the length of a side of a square whose area equals 8?
area - width = length
Calculate the length in centimeters of a side of a cube whose volume is 1.0 l?
10cm
How do you calculate the length of the whose breadth volume and height is given?
Length will equal the volume divided by the other two numbers.
How do you calculate the angle for length 2350 and height 500?
Find the angle whose tangent is 500/2350, about 12 degrees
What will be the voltage drop across two core cable whose length is 1500m and voltage is 24v dc and load is 2watt?
There is insufficient information in the question to answer it. You did not provide the size (gauge) of the cable. Please restate the question.
What is the length of the longest side of the triangle whose vertices have coordinates A(-1-2) B(42) and C(-24)?
Just calculate the length of the three sides using the distance formula, then compare which is largest.
How does a voltage controlled amplifier work?
A Voltage Controlled Amplifier or VCA is a device whose gain is set by the voltage level of a control signal.
Find the length of the hypotenuse of a right triangle whose legs are 8 and 15 units in length?
Find the length of the hypotenuse of a right triangle whose legs are 8 and 15 units in length.
What is the volume of a cube whose side length is 4cm?
The volume of a cube whose side length is 4 cm is: 64 cm3
what is current controller voltage source?
A voltage source whose voltage varies proportionally to a current flowing through some other path in the circuit.
How do you calculate the linear measurement of a circle?
In order to calculate the linear measurement of a circle, divide the circumference by pi to calculate the diameter of the circle. Then multiply the radius by 2 to find the diameter, and divide the radius by 0.5 to calculate the diameter.
The length of a side of a cube whose volume is 512 cm cubed?
The length of a side of a cube whose volume is 25cm3 is 5 centimeters.
