How do you calculate the phase current when working with a 10kw 3 phase electrical motor?
To calculate the phase current of a 10kW 3-phase motor, you can divide the total power (10kW) by the square root of 3 (approx. 1.732) and then divide that result by the line-to-line voltage. The formula is: Phase Current (Amps) = Power (W) / (√3 x Line-to-Line Voltage (V)).
What is the meaning of the term load shedding?
The term load shedding means the process of terminating or disconnecting the electrical currents on a line when the line is overloaded. Load Shedding is the deliberate shutdown of electric power in a part or parts of a power-distribution system, generally to prevent the failure of the entire system when the demand strains the capacity of the system
If my house has a 200 amp line what size generator would it take to run the house and have the same power?
Your house runs nowhere near 200 amps, so you need to make a list of appliances and fixtures that you use, or that you will need while the generator is running, and add their power consumption together. Add some extra capacity for growth and so the generator is not always at full power. Then talk to dealers about generators with the amount of power you need. To run the house on a generator with the same capacity as the service that you have in your house you would need a 50 Kilowatt generator.
How many amps does a 18000 watt generator provide at 120 volt 3 phase service?
The equation for power in a three-phase system is given by the following equation:P = 1.732 x line voltage x line current x power factorSo, to calculate the line current, we can manipulate this equation, as follows:line current = power / (1.732 x line voltage x power factor)As you make no mention of power factor, we shall assume the power factor is 1, and we also need to assume the 230 V you quote is a line voltage, so we can calculate the value of current as follows:line current = 18 000 / (1.732 x 120 x 1) = 86.6 A
What is the length of the line in millimeters?
By the line you mean? ------ 1 line = 2,116 mm (Line = old Englih unit of length)
How much power can a transmission line carry example how much power can a 69kv line carry compared to a 390kv line what is the formula for power capacity of a hvac line?
For a line of given cross section and material, the power capacity will depend on the current carried, since resistance heating is proportional to (current)2 . For a given power, current is inversely proportional to voltage. Thus raising the voltage from 69 to 390 kv would reduce the current by a factor 69/390 = 0.177 , for the same power transmission, and reduce the heating losses by 0.1772 = 0.031. So you can see why high voltage for long distance lines is essential. Obviously the limiting current on a power line has to be set by economic and practical considerations, but if this is predetermined and set, the limiting power will be that which produces that limiting current, and power = voltage x current. The actual limiting curent will depend on the line cross section, material, and length. The power that a line of a certain voltage can carry is calculated by using the following formula: (2.55×(KV)2 /1000) MW.

How do you Start three phase motors?
Three Phase Induction Motor is self starting motor so you can start it by conneting to power lines directly if the power line capacity is sufficient.
What is the maximum capacity for the water line in this building?
The maximum capacity for the water line in this building is 500 gallons per minute.
What is the purpose of having a low impedance for transmission lines?
in order to reduce the transmission line losses we need low impedance...Low impedance also improves power transfer capacity of the line..

A T1 line represents more line capacity than an E1 line.?
false
Which has greater line capacity T1 or E1?
The E1 has a greater line capacity. E1 is the European standard and runs at 2.084 Mbps. The American T-1 standard runs at a capacity of 1.544 Mbps.
How you can calculate current of a load when you have three phase supply with 237 volts328.4 KW Power and 0.99 cosfi?
The general equation for power in a BALANCED three-phase load is as follows:P = EL IL x power factor...where EL and IL are the line voltage and line current, respectively.So all you have to do is to manipulate the equation to make the line current the subject, and insert your figures.
A transmission line has 30 megawatts and 40 megavars what is the megavolt amps load on the line?
By definition, MVA is equivalent to the vector sum of MW and MVAR: MVA^2 = MW^2 + MVAR^2 = 2500 MVA = 50
What makes a power line work?
A power line works by electrons flowing through from power line to power line but if something interferes with the power lines the flow of electrons will not work. (flow)
How do you calculate 3 phase power factor?
The power factor for a three phase generator is 80 percent. The generator consumes 36 kilowatts and a line to line voltage of 400 volts.
