How is the total load in volt-amperes for lighting purpose determined?
LxW of building x 3 volt amps per sq. foot
How is the total lighting load in amperes determind?
The total lighting load in amperes is determined by first calculating the total wattage of all lighting fixtures in a circuit. This total wattage is then divided by the voltage of the circuit (usually 120V or 240V) using the formula: Amperes = Watts / Volts. Additionally, factors like the power factor (for non-resistive loads) may be considered to ensure accurate calculations. It's also important to account for any local codes or regulations that might affect the overall load calculation.
How is the load in volt amperes for lighting purposes determined?
LxW of building x 3 volt amps per sq. foot
If the 60 volts and the resistance of the load is 10 ohms the current is how many amperes?
6 amperes
How do you calculate lighting lpoad?
To calculate lighting load, you need to determine the total wattage of all the lights in the space. This is usually done by adding up the wattage of each light fixture or bulb. You can then convert this total wattage to kilowatts by dividing by 1000. Finally, multiply the total kilowatts by the number of hours the lights are on each day to calculate the daily lighting load in kilowatt-hours.
What are examples of amperes?
1 amp, 5 amp depends on the load
How the capacity of fuse is determined?
The capacity of a fuse is determined based on the expected current flow in the circuit. This is usually set slightly above the normal operating current to allow for surges without blowing the fuse unnecessarily. The capacity is typically indicated in amperes on the fuse itself.
Transformers are rated in what?
Transformers are rated in KVA. (this is because the transformer is Unity power factor device i.e.. PF = 1)AnswerThe selection of a transformer is determined by the apparent power of the load, expressed in volt amperes(V.A), the load current, and the line voltage of the supply. The transformer must be able to satisfy these requirements.Transformers are not 'unity power factor' devices, which is precisely why their capacity is expressed in volt amperes, rather than in watts.
Formula for 7.5va convert into Amperes load comsumption?
To convert 7.5 VA to amperes, you can use the formula: Amperes = VA / Volts. For example, if the voltage is 120V (typical for household circuits), then 7.5 VA / 120V = 0.0625 amperes.
Why capacitor can be defined in kvar?
Capacitors designed to be used for power-factor correction are rated in reactive volt amperes, rather than in farads.The reason for this is that in order to determine the necessary correction, a load's existing reactive volt amperes is first calculated, then the reactive volt amperes of the capacitor must be determined in order to achieve the required value of power factor. In other words, the capacitance (in farads) of the capacitor is irrelevant to the calculation.
How many amperes in kva?
It depends on the voltage and whether it is a single- or three-phase load.
