In anelectrical power substation, Capacitor Voltage Transformer in combination with Wave Trap is placed at the sending and receiving ends of the substation. At the receiving end, they are found just afterlightning arresterand before line isolator. Basic diagram of a Capacitor Coupled Voltage Transform...
Here, from the above diagram, Angle between OC and OD may be very small, so it can be neglected and OD is considered nearly equal to OC i.e. Voltage regulation of transformerat lagging power factor, Voltage Regulation of Transformer for Leading Power Factor ...

Fig. 5. Single-line diagram of New England 39 bus test system [60]. In the following sections, the outcomes to proposed methodology are presented, such as: the results of the execution of the VCAs identification algorithm, the results of the optimum KELM selection parameters, and the results...
Figure 1. One-line diagram of a university campus DC microgrid testbed in Korea. The AC network consists of an existing 0.38/0.34 kV transformer on each branch and a newly installed 0.34/0.38 kV transformer to match the voltage to the PCS. The secondary neutral of the PCS connection trans...
Figure 1 illustrates a single line diagram of a VSC connected to the point of common coupling (PCC) through an LCL filter which includes a step-up transformer. The voltage at the DC bus terminals is 𝑉𝑑𝑐Vdc, and the input current is 𝐼𝑑𝑐Idc. Figure 1. System description ...
Fig. 2c shows a single line diagram of the system configuration under study. It is composed of a 13 kV, 50 Hz generation system feeding two transmission lines through a three-winding transformer connected in Yg/Δ/Δ, 13/66/66 kV. Such transmission lines feed two distribution networks throu...
