How many KW of electrical equipment can be driven by 120KVA

Capacitance of 120kVA.

The electrical power that can be driven.

Load p = UICOS = 120 (kva) cos (kw) where ui is the apparent power s, unit va, the title gives 1200kva, cos is the power factor of electrical equipment.

Generally. For example, if the power factor is taken, the electrical capacity of 120kva can drive the load as: p = power load.

Look at what the total power factor of the load is.

The power factor is 108 kW.

The power factor is 102 kW.

The power factor is 96 kW.

q=u*i* is the power factor, which is the capacity in the transformer kva is the apparent power, and its size is related to the power factor! The active power p, the reactive power q, and the apparent power s have the following relationship p=s cos ( is the power factor) q=s sin s square = q square + p square For example: power factor cos = active power is p = 1kw then tg =, so the square of apparent power s = p square + p * tg square i.e. s = when the power factor is 1, 1kva = 1kw

Kilowatt (kW) = kilovolt amperes (kVA) multiplied by the power factor, assuming a power factor of 1Then a 50kVA transformer can drive a 50kw electrical appliance.

Volt amperes (KVA), the standard for measuring power, are 1 kilovolt amperes. KVA is equivalent to the current in a circuit generated by the voltage of that line, and is usually measured in a transformer, i.e. it is a unit of current.

The kilowatt refers to the power of an electrical appliance, that is, the unit of power. The rated capacity indicates the guaranteed value of the output power of the transformer under the rated working conditions, and is the apparent power of the transformer.

That is, the ability of the transformer to output the maximum electrical power, and the actual output power of the transformer cannot be confused with the capacity.

40kw, but the capacity of the largest motor cannot exceed 16kw

The output power of the transformer is the apparent power, and the relationship with the active power (kw) is: apparent power, active power, and power factor. In terms of average power factor, a 50 kva transformer can be a load power (50 kva of active power.

A transformer is a device that uses the principle of electromagnetic induction to change the alternating voltage, and the main components are the primary coil, the secondary coil and the iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulation (magnetic saturation transformer), etc.

According to the use, it can be divided into: power transformer and special transformer (electric furnace transformer, rectifier transformer, power frequency test transformer, voltage regulator, mining transformer, audio transformer, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.). Circuit symbols often start with t.

Summary. Hello, dear <>

A 110 kW electric motor requires a transformer with a capacity of at least 125 kva! Because, the best value of transformer working efficiency is 85-90% of the transformer! That is, if the power factor of a 125kVA transformer is 1, it can have a load of 125kw.

However, in actual work, it is difficult to achieve the ideal state of 1 in the economic operation efficiency of the transformer! Most of the time it can only be achieved between, so the economical operating efficiency of a 125kVA transformer can only be. Therefore, if your maximum power is only 110k, you can choose a 125kva transformer, if you want to leave a margin, then choose a 160kva transformer!

I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

I hope my answer is helpful to you, and finally I wish you good health and a happy mood again! <>

<> some of them said that they wanted 250kw if it was not so big, I think it should be enough to buy 200kw.

Hello, dear <>

That's enough, it doesn't have to be that big. Good.

Summary. Dear, I'm glad to answer for you! A 50kva transformer can carry 30kw.

The transformer has a certain efficiency loss, which needs to be calculated according to the low standard of 60% 50kw * 60% = 30kw is appropriate, and can not be used at full power to avoid the transformer heating and burning. <>

Dear, I'm glad to answer for you! A 50kva transformer can carry 30kw. The transformer has a certain efficiency loss, and it is advisable to calculate 50kw * 60% = 30kw according to the low standard of 60%, and it cannot be used at full power, so as to avoid the early dust of the land dust and the transformer is heated and burned.

A transformer is an electrically stuffy device that can raise or lower the voltage from a certain level. In alternating current systems, transformers are used to reduce the voltage of high-voltage transmission lines to low-voltage power suitable for user use. The unit of a transformer is kilovar voltammetry ampere (kVA), which indicates the rated capacity of the transformer.

Hello dear, you want to know how many kW can be carried by a 50kva transformer, right? How many kW can be carried by a 50kVA transformer is not a fixed number, depending on the parameters such as the rated power, rated voltage and conversion ratio of the transformer. In general, the conversion relationship between the rated capacity of the transformer and the load power that can be carried is as follows:

When working on the low voltage side, the conversion formula between capacity and power is: capacity (kva) = voltage (v) current (a) 1000. When working on the high-voltage side, the conversion formula between capacity and power is:

Capacity(kva) = Voltage(V) Current(a) Conversion ratio 1000. For example, if a 50kVA transformer works on the low voltage side with a voltage of 400V, then the maximum load power it can carry is 50kW; If it works on the high voltage side with a voltage of 10 kV (a conversion ratio of 1:20), then it can carry a load power of 50 kW.

It should be noted that when using the transformer, it should be avoided as much as possible to overload the ear code or stay in the full load state for a long time, so as not to cause excessive loss and heat loss to the transformer, and reduce the life and efficiency of the transformer. At the same time, attention should be paid to load balancing and stability to avoid overloading the transformer due to excessive or unbalanced single-phase loads.
