Power requirements are measured in KVA, which stands for Kilo-Volt-Amperes. To calculate the amount of power you require you would use the following formula.
KVA = Volts * Amps / 1000
Formula for what?!
The secondary current is determined by the load. So, divide the secondary voltage by the load impedance.
You first have to find out what the load amperage is going to be and second, what is the working voltage.
The question has to be more specific. Full load amps, watts or voltage. Please restate your question.
In this case, to get the equivalent resistance, first you use the parallel formula (1/R = 1/R1 + 1/R2) to calculate the equivalent resistors in parallel. Then you calculate the series resistance of this combination, with the other resistor.
no load voltage - full load voltage by full load voltage
Formula for what?!
The formula you are looking for is I = Watts/ Voltage, I = 3000/voltage.
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
To calculate the load on a 2.5 square mm cable, you can use the formula: Load (in watts) = Current (in amps) × Voltage (in volts). The maximum current that a 2.5 mm² cable can safely carry depends on factors such as insulation type and installation conditions, typically around 20-25 amps for standard installations. To find the load capacity, multiply the maximum current by the voltage of the circuit. Always consult local electrical codes for specific guidelines and safety standards.
To calculate the DG set current, you need the load current and the load voltage. To convert it into kilowatts it is divided by 1000.
To convert kilowatts to amps, you need to know the voltage of the circuit. The formula to calculate amps is: Amps = kilowatts / (volts * power factor). For example, if the voltage is 120V, then the amps would be 100A for a 12kW load.
Phase angle is defined as the angle by which the load current leads or lags the supply voltage in an AC circuit. There are numerous ways to calculate a circuit's phase angle, so there is no 'formula' as such. For example, if you know a load's resistance and impedance, or its true power and apparent power, then you can use basic trigonometry to calculate the phase angle, and so on.
Summation of individual load connected on the board gives the total load. Power (Load ) = Voltage x rated current.
There are various formula of load calculation. Power equals current multiplied by the voltage. Power can also be computed by multiplying the resistance by the square of the current.
To calculate the amperage of a 40 kVA load, you will need to know the voltage. The formula is: Amps = kVA / Volts. Assuming a standard line voltage of 120V, the amperage for a 40 kVA load would be approximately 333 amps.
The secondary current is calculated by dividing the secondary current by the impedance of the load. This value shouldn't exceed the secondary-winding's rated current except for short periods of time.
