These substations receive power from the electrical generators at a lower voltage and sends it to a transmission line at a higher voltage. A generating substation has main
The lines are fed into intermediate substations (4a and 4b) where transformers reduce the voltage to 11 kV. Secondary distribution lines radiating from these substations carry the power into the
When generators at a consumer''s substation operate in island mode (Utility power supply disconnected) the voltage and the frequency at the main substation level are both fixed
The electrical substations can be divided into public substations and private substations: se or three-phase current (typical values of the voltage for the two types of power supply can be
Generators can have different ratings indicating overall operating capacity shown below: Standby: 60 to 70% of the rating for 24-hour periods up to 500 hours per year operating time. Emergency Standby: 60 to 70% of the rating for 24-hour

Sub-stations are an important part of the power system. The four major types of substations are generating, customer, system and distribution substation.
Substations do not (usually) have generators, although a power plant may have a substation nearby. A typical substation will contain line termination structures, high-voltage switchgear, one or more power transformers, low voltage switchgear, surge protection, controls, grounding (earthing) system, and metering.
Substation are used to transform the voltage with power transformer. From low voltage to high voltage at the power plant with breaker and control system to be able to transport the energy, and other substation at the arrival to decrease the voltage.
Substations. Application. This section provides additional requirements for substations and for work performed in them. Access and working space. The employer shall provide and maintain sufficient access and working space about electric equipment to permit ready and safe operation and maintenance of such equipment by employees.
This article highlights OSHA's requirements for substations and work within substations. Substations have significant step and touch and arc flash hazards located within relatively small, restricted areas. Various types of non-electrical and electrical work are performed inside areas with extremely high voltages and minimal air clearances.
When generators at a consumer's substation operate in island mode (Utility power supply disconnected) the voltage and the frequency at the main substation level are both fixed by the generators and consequently the control system of the generators operate in Voltage/Frequency mode (see Fig. B46).
A typical substation will contain line termination structures, high-voltage switchgear, one or more power transformers, low voltage switchgear, surge protection, controls, grounding (earthing) system, and metering. Other devices such as power factor correction capacitors and voltage regulators may also be located at a substation.
