500 kVA Transformer, Get The Price Quickly
500 kVA transformers are generally used in power distribution systems. A power grid is a network connected by distribution and transmission lines, of which generation, transmission, and distribution are major parts. A transformer converts an input voltage to a higher or lower output voltage. The transformer enables the power generated by the substation to be boosted for long-distance transmission first and then stepped down to the home, providing convenience for consumers.
Generally speaking, the transformer consists of two windings, a primary winding, and a secondary winding. The input power on one side flows through the primary winding and then enters the secondary winding. Finally, the secondary winding converts the power and inputs it into the lead to transmit to the load. The rating or size of a transformer is its power level in kVA.

What is the meaning of a 500 kVA transformer?
Transformers rated at 500kva are generally referred to as 500kVA transformers. Of course, it can also be understood that in a safe operating environment, the highest operating load that a transformer can carry is 500kva. KVA can be used to indicate the capacity of the transformer. In general, there are other load resistances on the operating circuit and the actual power of the transformer is below ideal power. The actual output capacity is the product of the voltage when there is a load, the rated current, and the corresponding coefficient.

What is the output voltage of a 500kVA transformer?
Even if the single-phase transformer and the three-phase transformer have the same rated power of 500kva, their output voltages are different. The output voltage of a three-phase transformer is generally different from that of a single-phase transformer, and the output voltage of a three-phase transformer is generally higher than that of a single-phase transformer. The output voltage of the three-phase transformer is generally 208/240/400/480/600V or others, while the output voltage of the single-phase transformer is generally 120-240v, 240-480v, or others.
How to install a 500 kVA transformer?
Some professional inspections and tests should be done before installing a 500kva transformer to ensure safety:
1. Carefully read the instructions of the transformer, confirm the model and specifications of the transformer, and check the quantity of transformer accessories and whether there is any quality problem.
2. Check the transformer body and accessories for damage and oil leakage. If there is oil leakage, the installation should be suspended.
3. Before installation, the transformer oil should be subjected to a withstand voltage test. The standard of new oil is: that the withstand voltage below 1.5kV should not be lower than 25kV.
4. Before installation, the insulation resistance should be tested, and the insulation resistance value should be at the same temperature.

How many amps can a 500 kVA transformer supply？
Amp is the basic unit for expressing current in the International System of Units. Commonly used units are ka and ma. Regarding this issue, single-phase transformers are different from three-phase transformers.
In general, the formula for calculating the rated current value of a single-phase transformer is to divide the rated capacity by the rated voltage, and then multiply the value obtained by 1000. The formula for calculating the rated current of a three-phase transformer is relatively complex, that is, after dividing the rated capacity by the rated voltage, then dividing by 1.732, and finally multiplying by 1000, the obtained value is the rated current value.
Obviously, the different rated voltage will also lead to the transformer's different current value, that is, the ampere value.
Therefore, if the 500kva transformer is a single-phase transformer and the rated voltage is 120v, 500/120*1000=4166A.
If 500kva is a three-phase transformer and the rated voltage is 480v, 500/480/1.732*1000=601A

500kva oil-filled transformer
Generally speaking, most oil-filled transformers use mineral oil to insulate and cool the equipment, so as to prevent its high temperature from damaging the body. Sometimes, fans and external radiators are installed in the transformers to speed up heat dissipation. A small number of transformers also use seed oil for insulation and cooling. The oil-immersed transformer has a long service life, generally up to 20 years or more, but it also needs regular maintenance to maintain and improve the working efficiency and prolong its service life. The maintenance of an oil-immersed transformer mainly includes the measurement and testing of different parameters. Generally, there are two maintenance methods, namely daily maintenance and temporary maintenance, which can also be called on-demand maintenance or on-demand maintenance.
