What is the current in each phase of a 15 kW three-phase electricity?

Introduction What is the current in each phase of a 15 KW three-phase electricity? If it is used in a 380V system and it is a resistive load (power factor is 1), then the current I: I = 15KW/(

What is the current in each phase of a 15 kW three-phase electricity?

If used in a 380V system and it is a resistive load (power factor is 1), then current I:

I =15KW /(root 3x380Vx1)≈22.8A

If it is an inductive load, the power factor can be 0.8-0.9 depending on the nameplate parameters or calculations.

I have a 15KW, 380V three-phase motor. How many square meters of wire should I use?

The starting current of the generator is relatively large, I recommend at least 2. times the power, 15KW*2=30KVA, for long-term operation, it is recommended that 40KVA voltage stabilizer is better. This is a three-phase voltage stabilizer instead of a single-phase voltage stabilizer. to be balanced. You can have a live wire + a neutral wire, which is two outputs, but you need to pay attention to one thing, A B C three phase, the A phase load is much higher than B C two phase, the svoltage stabilizer. will heat up, shorten its lifespan or even burn directly. The most minor problem is that the voltage stabilizer loss and line loss will increase, that is, the power consumption will increase. Yes, the solution is to balance the load on everyone. phase. Our company specializes in the production of voltage stabilizers. These powers are all in stock See my information

What is the current of a 15KW generator

6 square meters. of copper wire.

The 15 kW three-phase motor does not provide the number of poles. The rated current is estimated to be larger, 30 A. Calculated based on 3 A/mm2, a 10 mm2 cable is required. According to empirical calculations, twice the kilowatt of a 15 kW motor is essentially the rated current. The current is calculated as 30 currents.

Three-phase asynchronous motor 380 V AC, the rated current of the motor is approximately 30 A if it is notIt's not far from the transformer, 6 square meters of copper wire are enough, and 10 square meters of aluminum wire. can also meet the requirements.

Detailed information:

< p>Note:

Under rated cooling conditions, the motor may operate within the rating specified on the manufacturer's nameplate. Motors with unclear limits are not permitted to operate blindly.

The maximum monitoring temperature of the motor coil and iron core should be implemented according to the manufacturer's regulations.

The allowable temperature of the motor bearings must comply with the manufacturer's regulations. When there are no manufacturing regulations, for plain bearings, the temperature must not exceed 80°C, and for bearings, the temperature must not exceed 100°C (whenthat the quality of the grease is poor, the temperature must not exceed 85°C).

Baidu Encyclopedia - Three-phase motor

First choice, the capacity of the generator cannot be expressed in KW. It should be 15 KVA, indicating the apparent power. The active power of its output electric energy generally does not reach 15KW. Related to power factor. But the size of the current remains unchanged and the calculation method is (three-phase, output voltage 380 V): 15000/1.732/380 = 23 A.

It is different from the motor. The electric motor can use energy (i.e. active power) to mark capacity. A 15 kW motor means that the output shaft power of the motor is 15 kW and the power consumption is about 16 kW (the efficiency is about 95%). Power factor is about 0.8, current = 15000/1.732/380/0.80/0.95 = 30 A
