4 Common Arrangements of Distribution Substations
The general technique of supplying large quantity of power to factories or other complexes is by means of high-voltage (HV) supply, typically at 11 kV, occasionally at 6.6 kV. The installation consists of a main substation at the point of entry, with HV cables to supply subsidiary substations located near load centres. Where necessary, it…

Transformer Substations in an Electric Power Supply System
The greater part of the substations in the power systems are focused on changing of the voltage level of the electric supply. These are termed to as transformer substations since the transformer is the key component used to change the voltage level. Transformer substations may be classified further into the following substations depending on the…

Features and Classification of Substations
A substation can be defined as an assembly of apparatus used to change some characteristics like voltage, AC, DC, frequency, power factor, etc., of electric supply. Substations play a key role in power systems. The continuity of supply depends largely upon the successful operation of substations. Thus, it is imperative to exercise utmost care while…

Key Factors to Consider In Substation Design
Substations are the points in the power network where transmission lines and distribution feeders are connected together through circuit breakers or switches via busbars and transformers. This permits the control of power flows in the network and the normal switching operations for maintenance purposes. We discuss the key factors to consider when designing substations as…
