Substation Job Description

A substation is an important part of the electric power grid. It is a facility where electricity is generated, transformed, and distributed to consumers. A substation can be as simple as a single transformer that steps down the voltage from the transmission line to a lower voltage that can be used by customers.

However, most substations are much more complex, with multiple transformers, circuit breakers, and other equipment. The primary function of a substation is to switch electrical energy from one form or another. For example, a typical substation might receive electricity at high voltages from the transmission grid, step it down to lower voltages for distribution to customers, and then step it back up again for return to the transmission grid.

Substations also provide essential protection for both the utility’s equipment and personnel, as well as for the public. Circuit breakers in particular play a vital role in preventing damage to equipment and injuries to people during faults or other abnormal conditions on the electrical system. Substation jobs can vary widely in scope and responsibility.

Some positions may require only basic maintenance tasks such as checking oil levels and cleaning debris from around equipment. Other jobs may involve more complex duties such as testing circuit breakers or repairing transformer coils. Still other positions may be responsible for all aspects of substation operations, including planning and scheduling work, coordinating with other utilities or agencies, overseeing construction projects, and responding to emergencies.

Substation Tender Meaning

Substation Tender Meaning: A substation tender is a formal document that is issued by an electrical utility company in order to solicit bids from contractors for the construction of a new substation. The substation tender will include all of the specifications and requirements for the project, as well as information about the timeline and budget.

What are the Duties in Substation?

The duties of a substation are to receive, transmit and distribute electric power. They may also be responsible for monitoring and regulating the flow of electricity in the system, as well as maintaining safety standards.

What are the Different Types of Sub Station?

An electrical substation is a facility where voltage is transformed from high to low, or the reverse, using transformers. Electric power may flow through several substations between generating plants and end users, often called transmission substations when located along transmission lines and distribution substations when located near the customers. Substations come in a variety of shapes and sizes.

Some are as small as a single transformer connected to a switchgear while others occupy acres of land with multiple buildings full of equipment. The primary function of any substation is to bring together pieces of electrical equipment so that they can operate safely and efficiently together. The three main types of substations are:

-Transmission Substations -Distribution Substations -Conversion Substations

A Transmission Substation takes electricity at very high voltages (usually 115kV, 138kV, 161kV, 230kV or 345kV) from the transmission grid and steps it down to a lower voltage (usually 69kV) so that it can be fed into the distribution network. A typical configuration for a 115/69 kv two winding transformer would be shown in figure 1 below. The primary winding (115 kv side) is physically much larger than the secondary winding (69 kv side).

This is because at the higher voltages more current flows through the conductor for a given amount of power transferred than at lower voltages. This means that for an equivalent power rating (measured in MVA), the conductor size required will be smaller at 115 kv than at 69 kv. Consequently, the overall physical size (and weight) of the transformer will be smaller if operated at 115 kv rather than 69 kv – this has important implications regarding transportation costs and siting restrictions within stations.

. These are typically located near population centers so that shorter lengths of lower voltage cable can be used instead of longer lengths of higher voltage cable.. Various combinations transformers are used depending on circumstances but usually entail one or more three phase units operating at either 11 kv or 33 kv with corresponding single phase units also present..

What is Meant by Sub Station?

Substations are an essential part of the electricity supply system. They help to ensure a reliable and high quality electricity supply by transforming voltages from high to low, or vice versa. Substations also play a vital role in controlling the flow of electricity around the network.

There are three main types of substation: transmission, distribution and generation. Transmission substations connect parts of the national grid – they step down voltage from 400,000 volts (400 kV) to 275,000 volts (275 kV) for onward transmission. Distribution substations take power from the grid at lower voltages – usually between 132,000 volts (132 kV) and 33,000 volts (33 kV).

These voltages are then transformed down to 11,000 volts (11 kV) before being distributed to homes and businesses through medium-voltage cables. Generation substations connect power stations to the national grid. Substations come in all shapes and sizes but typically they will have a number of key components including transformers, switchgear and control equipment.

The layout of a substation will be designed to suit its purpose – for example, transmission substations will often have large open spaces between buildings to allow for maintenance access; whereas generation or distribution substations might be more compact due to their location within built-up areas.

What are the Duties of a Substation Electrician?

As a substation electrician, your duties would include installing, maintaining and repairing high-voltage equipment and systems. This would involve working with voltages of up to 138,000 volts. You would also be responsible for testing equipment and conducting routine maintenance checks.

In the event of an emergency, you would need to be able to troubleshoot problems and make repairs quickly.


A sub station attendant is responsible for the maintenance and upkeep of a substation. Their duties include checking equipment, performing repairs, and keeping the area clean. They may also be required to respond to emergencies.
