The transformer size is calculated by using the load current that is required on the secondary side of the transformer. This secondary current is multiplied by the secondary voltage times 1.73. This total is then divided by 1000 to give you KVA. KVA = I x E x 1.73/1000.

Why would a generator put out 240 volt single phase?

For a home generator, to supply voltage for devices that require 220 V or 240 V. An electric oven or clothes dryer are examples of such devices. The generator at the power plant actually generates electricity at a much higher voltage, for easier transmission (and those are 3-phase generators). Also most homes run on 240 single phase. Power is split at the breaker box. To supply 120 loads and 240 loads. 240 single phase is a common voltage.


How do you calculate The Percentage Voltage Drop?

The percentage voltage drop is calculated using the formula: [ \text{Percentage Voltage Drop} = \left( \frac{V_{drop}}{V_{supply}} \right) \times 100 ] where ( V_{drop} ) is the voltage drop across the load or conductor, and ( V_{supply} ) is the supply voltage. Measure the voltage at the load and subtract it from the supply voltage to find ( V_{drop} ). Then, apply the formula to express the voltage drop as a percentage of the supply voltage.


How do you calculate amp draw if you have a 25KW strip heater?

Divide 25,000 by the supply voltage to get the current.


LVDT's can you have multiple devices on one dc supply?

Yes, you can connect multiple Linear Variable Differential Transformers (LVDTs) to a single DC power supply, provided that the power supply can handle the combined current requirements of all the LVDTs. It's important to ensure that the supply voltage is appropriate for each LVDT and that the total load does not exceed the power supply's rating. Additionally, proper wiring and signal isolation techniques should be used to avoid interference between devices.


Which laser printer component converts AC line voltage into the DC voltages the printer can use?

As in all electronics devices that obtain power from the AC electric system, a power supply converts the AC to the DC voltage(s) needed by the electronics in the device. Depending on the needs of the device this power supply may deliver a single DC voltage or as many as several dozen different DC voltages.

How can I prevent voltage fluctuations in my house to protect my electronic devices and appliances?

To prevent voltage fluctuations in your house and protect your electronic devices and appliances, you can use surge protectors, voltage regulators, and uninterruptible power supply (UPS) systems. These devices help stabilize and regulate the voltage supply to your devices, reducing the risk of damage from sudden spikes or drops in voltage. Additionally, ensuring proper grounding and wiring in your home can also help prevent voltage fluctuations.


What will happen if you use phase to phase voltage for a single phase device?

If a single-phase device is connected to a phase-to-phase voltage, the device may get damaged due to the higher voltage applied. Single-phase devices are designed to operate at a lower voltage compared to phase-to-phase voltage levels typically found in three-phase systems. It is important to match the voltage ratings of the device with the supply voltage to prevent damage.

What size wire 100 kva transformer?

Wire sizing of a feed conductor is based on the amperage that a device draws. To calculate amperage from KVA a voltage of the supply has to be stated. Without this voltage and whether the transformer is single or three phase an answer can not be given.
