Substation Transformer

Appendix D Substation and Cable Route Design Report

Substation and includes a control building, bus structures, switchgear, and a step-up transformer. The project Substation will be connected to the leveland Public Powerexisting 69 kV system at the C Substation via an overhead gen-tie circuit. Detailed engineering design of the substation will be part of the 100% Front End Engineering Design.

substation will trip to isolate the faulty circuit. Ringed network arrangement A typical customer substation in a ring-configured network contains two feeders and one transformer feeder. The former have circuit breakers and cable connecting to other substations while the latter has circuit breaker and cable connecting to 11kV/LV transformer.

Loading Considerations when Paralleling Transformers

It can be seen by using equations (1) and (2) below, that if the percent impedances in each transformer are the same, as shown in Figure 1, that there will be equal current division and load sharing on each transformer. (1) (2) Where I. 1 = load current from transformer 1 I. 2 = load current from transformer 2 Z. 1 = % impedance of transformer ...
