The company has a 1000KVA transformer. The load is also close to 1000KVA, I have a capacitor bank of

It has nothing to do with the transformer, and the reactive power required by the transformer is provided by the high-voltage grid. It depends on what load you have, if it is a pure resistance load, there is no need for reactive power, and the inductive load has to compensate for reactive power, the motor is calculated per kilowatt, and the AC welding machine is calculated according to 1kvar per kva, and then the required capacitance is installed.

The size of this compensation is determined according to the load, regardless of the size of the transformer.

For example, your load may be a motor, but the power of the motor and the load situation when working may make the compensation change very large; In addition, whether the load generates harmonics, such as DC load, inverter, etc., will also change the amount of compensation.

For example, I have done a manufacturer's compensation, which is a 315kva transformer, but the final compensation amount is determined to be 700kvar, and the actual compensation amount is 640kvar: it is more small motors, and there are many when there is no load or light load.

You see, that's the effect of the load on the amount of compensation.

I am a professional in reactive power compensation and filtering, if you need to determine something, welcome to continue the communication.

Depending on the nature of the load under your transformer, the low original power factor needs to be compensated more, and the high power factor can be compensated less. If it can be measured, it is recommended to measure it first to see the size of the reactive power demand.

It can be judged according to the actual situation. I wonder if your load is emotional or resistive?

The power factor proves that your electricity consumption is not small. The grouping of 16 groups should also be reasonable Wang Qing. If you can't vote, you should first check the controller to see if the controller is not set up properly, or it is broken at all.

If it's a problem with the controller, just reset the controller or replace it. If the controller is fine, then you should consider the problem of harmonics. Because if the harmonic content in the system is large, the capacitor will amplify the harmonic wavelength current, and the capacitor will naturally not be able to be cast when the current is large.

If this is the case, it is necessary to install a set of filtering compensation devices on the Liling key. If the main components in your capacitor cabinet are of the right specifications, they can also be transformed, so that the cost can be less.

Summary. Hello, I am a life expert little durian, I am happy to answer your questions, 200kva transformer full load, distribution capacitance compensation cabinet capacitance capacity you can choose as follows: take 200kva transformer, flat view in the power factor reactive power compensation to increase the power factor to an example.

200kva transformer load power: p 200 reactive power at power factor: q1 root number (s1 s1 p p) root number (200 200 140 140) 143 (kvar) apparent power when the power factor is increased to:

S2 140 Reactive power: Q2 root number (S2 S2 P P) root number (147 147 140 140) 45 (kvar) capacitance reactive power compensation: QC Q1 Q2 143 45 98 (kvar) capacitance compensation cabinet is divided into 10 groups of capacitors, each group of compensation is 10kvar.

How to choose the capacitance capacity of the distribution capacitor compensation cabinet when the 200kVA transformer is fully loaded?

How long do you have to wait? Hello, I am a life expert little durian, I am happy to answer your questions, 200kva transformer full load, distribution capacitance compensation cabinet capacitance capacity you can choose as follows: take 200kva transformer, flat view in the power factor reactive power compensation to increase the power factor to an example.

If you want to divide into 4 groups, can you make up the taste?

Is it okay to divide into five groups?

What is the amount of kvar per group?

It can be divided into five groups, but you still need to ask a professional to correct this, after all, we are not professional, just to give a suggestion.

250kva*。

After the power consumption plan approved by the power supply bureau, you can see the power factor, power consumption coefficient, calculated power and other detailed technical parameters of the equipment, which must be produced in strict accordance with the design drawings.

The nature of use is different, the amount of compensation is also very different, and the nature of use is roughly divided into two categories: industrial and civil. The compensation requirements for civil use are relatively low, and the compensation coefficient required by industrial projects is relatively high, with 30% of the nominal capacity of civil general compensation transformers and 70% of the nominal capacity of industrial general compensation transformers.

If the average work leakage rate factor increases from to time, the amount of low-voltage reactive power compensation capacitor:

The transformer is 200 kilowatts, and the load is 280 kilowatts, how to distribute the compensation capacitor?

If calculated according to the transformer, it is generally estimated, that is, the capacity of the reputation to about that, if the motor load is multi-faceted, then choose, that is, 120 thousand missing, if it is calculated according to the load, the average power factor of the general load is about nearby, if it is increased to the time, the capacitance compensation per kW power is required, you are 280kw so you want 280 *, with 200 thousand lack on it, but your transformer can no longer bear your load, you must increase the trace of the void.
