It is necessary to do an accurate calculation to get the most optimal capacitor installation results. Calculations are carried out by using the power factor correction diagram method to find the reactive power demand. The reactive power demand at the load center was calculated by the average of its three phases of 600 kVAR. However, a new challenge occurs when the

The 10kv transformer is usually referred to as a "distribution" transformer. This is because it uses the law of electromagnetic induction to transmit alternating current (AC) steps down the voltage from the primary to the secondary winding. The secondary winding provides the lower voltage that the customer uses. sales@daelim-electric pingruidan@gmail +86 15801656761; 678

All equipment shall be functionally complete. All equipment shall be completely engineered, fabricated, pre-wired and ready for installation into an operating condition. Field assembly shall not be required. The manufacturer of the enclosure shall also be the assembler of the capacitor bank.
The uniqueness of this scenario lies in the decision to install the capacitor bank at the 11 KV voltage level, even though the factory receives power from the grid at a higher voltage level of 132kV, with an approved connection capacity of 12 megawatts.
In this section, we delve into a practical case study involving the selection and calculation of a capacitor bank situated within a 132 by 11 KV substation. The primary objective of this capacitor bank is to enhance the power factor of a factory.
Moreover, the protection settings for the capacitor bank unfold systematically, elucidating the process of selecting the current transformer ratio, calculating rated and maximum overload currents, and determining the percentage impedance for fault MVA calculations.
