A vector is a mathematical representation of a physical quantity that has both magnitude and direction. In electric power systems, vectors are used to represent the voltage and current at a specific point in the system. The voltage and current at any given point can be represented by a vector sum of the voltages and currents at all other points in the system.
Substation Vector is an online tool that helps electric utility companies manage and control their substations. It provides a birds-eye view of all the equipment in a substation, as well as real-time data on power flows, voltage levels, and other conditions. This information can be used to improve the efficiency of substation operations and help prevent outages.

What are the Three Types of Substations?
Substations come in a variety of shapes and sizes, but all perform the same basic function: to step down high-voltage electricity to a lower voltage so it can be used by consumers. There are three main types of substations: transmission, distribution, and service.
Transmission substations are located between the power plant and the distribution grid.
They take in high-voltage electricity from the generator (usually at 115kV or 230kV) and use transformers to step it down to a lower voltage for transmission on the grid (usually 138kV or 345kV). These substations also have devices like circuit breakers and capacitors that help regulate the flow of electricity.
Distribution substations are located throughout a city or town, close to where people use electricity.
Electricity from the transmission grid enters these substations at a low voltage (138kV or 345kV) and is stepped down even further using transformers (to 12 kV or 25 kV). From there, it flows through underground cables or overhead wires to homes and businesses.
Service substations are small facilities that deliver electricity directly to consumers.
These substations take in power at 12 kV or 25 kv from the distribution grid and then step it down using transformers to 240 V or 120 V for household use. Some service substations also have equipment for monitoring and controlling the flow of electricity.
What is an Emf Substation?
An EMF substation is a power station that uses electromagnetism to generate electricity. These stations use large magnets to create an electromagnetic field, which then induces a current in a conductor, such as a wire. This current can then be used to power electrical devices.
What is a Substation And How Does It Work?
A substation is a critical part of the electrical grid. It is a collection of equipment that transforms high-voltage electricity from transmission lines into the lower voltages used by businesses and homes. Substations can also be used to switch power between different parts of the grid.
The heart of every substation is the transformer. Transformers use principles of electromagnetism to convert high-voltage electricity into low voltage, or vice versa. The primary winding, made of heavy copper wire, is wrapped around an iron core.
An alternating current flowing through the primary creates a magnetic field in the core. This, in turn, induces a voltage in the secondary winding, which is wrapped around the outside of the primary (and usually has many more turns). The ratio of turns in the secondary winding to those in the primary determines how much the voltage will be increased or decreased – this transformation can be as high as 150 times for some power lines.
Substations also contain circuit breakers, which are devices that protect equipment from damage due to faults or overloads by automatically opening and closing circuits as needed. Circuit breakers are essential for preventing cascading failures, which occur when one overloaded section of line causes a chain reaction that overloads other sections until eventually most or all of the system fails.
Finally, substations typically have control systems that allow operators to remotely monitor and control equipment at the site.
These systems may include supervisory control and data acquisition (SCADA) systems, human-machine interfaces (HMIs), programmable logic controllers (PLCs), and/or distributed control systems (DCSs).
What is the Difference between a Substation And a Transformer?
A substation is an assembly of equipment for transforming, switching, or distributing electric power. A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

Conclusion
A substation is a critical part of the electrical grid, providing a link between generating stations and consumers. The purpose of a substation is to change the voltage of electricity so that it can be used by customers. A substation consists of transformers, circuit breakers, and other equipment.
A vector is an electrical quantity that has both magnitude and direction. The three most common vectors used in power systems are voltage, current, and power.
