An electrical substation is a subsidiary station of an electricity generation, transmission and distribution system where voltage is transformed from high to low or the reverse using

Substations play several key roles in the electrical grid: Voltage Transformation: The most important function of substations is to transform voltage levels. This function ensures that electricity is produced, transmitted, and distributed efficiently and safely. Power Factor Correction: Substations help maintain the power factor close to unity.

Subtransmission voltages are usually between 26 kV and 69 kV. i) A step-up substation connects the power plant to the transmission lines. ii) A step-down substation connects the transmission lines to sub-transmission or distribution lines. iii) A distribution substation connects subtransmission lines to the distribution lines.

A substation is a high-voltage electrical system and can be used to control generators, electrical circuits, equipment, etc. Some types of substations are not small in size which includes inbuilt transfer as well as its associated switches. Other types of substations with transformers, equipment, circuit breakers, and switches are very

An 11kV substation is a type of electrical substation that uses 11,000 volts (11 kV) of alternating current (AC) to distribute power to end users. This voltage is used in many parts of the world for the distribution of electricity. The vast majority of 11kV substations are located in Europe and Asia. In an 11kV substation, the primary equipment
