In practice, the power loss on dis-tribution transformers can account for a considerable portion of the overall loss. This paper proposes a method for optimal place-ment of capacitor banks to the distribution transformers to re-duce power loss. The capacitor bank locations are considered at the low-side of transformers.
On the other hand, utilities often install shunt capacitors, as these offer many and varied benefits: reduction of network losses, improvement of network voltage profiles, better voltage regulation, increase of network generation hosting capacity, release of transmission and distribution system capacity, which all typically result in the increased revenue and deferral or full elimination of

capacitor installation bus locations and ratings are simulta-neously determined for three sub-circuits corresponding to transformers of a substation within a large 48MW, 9Mvar example power distribution system, which is made possible through an automated model conversion procedure of actual large-scale utility distribution systems.
They are classified into two types: single-phase transformer and three-phase transformer. The calculation of their capacity is crucial in determining their suitability for various applications. For a single-phase transformer, the capacity is calculated using the following formula: Capacity (kVA) = (Voltage x Current) / 1000

The balance between transformer capacity and energy distribution needs has become crucial. It ensures the electrical grid remains strong and functional.

The study involves the deployment of 3.42MVAr capacitor banks in 20kV, 4-bus-bar systems and 1.164MVar capacitor banks in 0.4kV, 2-bus-bar systems. The impact is thoroughly analyzed through measurements and pre/post-installation studies
A data logger is installed on the substation and the load data is recorded for one year. Additionally, the impact of different parameters like ambient temperature is investigated for optimal determination of transformer capacity. Index Terms: Distribution Transformer, IEC 60076-7, Capacity Determination, DSO, Practical Load.
In seasonal and rural regions, the load in summer seasons is significantly higher than the other periods of the year . Additionally, different parameters like variable ambient temperature have a considerable impact on the needed capacity of electrical distribution transformers.
Research results The placement of capacitors resulted in improved voltage levels across the distribution network. Voltage deviations from the nominal value were significantly reduced. There was a notable reduction in active power losses (I2R losses) throughout the distribution lines.
According to the current limitation from IEC 60076-7, the load must not exceed 1.5 multiples of the transformer rated load. Accordingly, with the peak load of 140.5 KVA, 25 and 50 KVA transformers are not proper choices for the measured load.
Distribution systems commonly face issues such as high power losses and poor voltage profiles, primarily due to low power factors resulting in increased current and additional active power losses. This article focuses on assessing the static effects of capacitor bank integration in distribution systems.
Also the Capacitors reduce the current flowing through the distribution lines, which directly decreases I2R losses (active power losses). This leads to more efficient energy distribution, and Reducing Active Power Losses. The Capacitors provide reactive power locally, which improves the power factor of the system.
