A substation is basically a group of electrical devices that are assembled and connected in one location.
The top part of substations are electrical devices that are capable of controlling and protecting other electrical devices for a full and stable operation.
Each of the electrical devices in a substation plays a vital role in terms of performance.
If one device is not working properly, it could possibly affect the entire operation of the substation.
In simpler terms, a substation is needed for all transmission and distribution systems.
This includes the electrical generation as well. Basically, a substation is responsible for transforming high voltages to low voltages, or vice versa.
A substation is also capable of dispatching electrical power from generating stations towards the center of consumption.
In simpler terms, the flow of electricity will be directed to more than one substation.
Furthermore, it is expected that its direction will also come across in between generating plants towards the customer (houses and other building). During this process, the voltage will change by steps.
So, if you are looking for a substation that provides just the right amount of electricity you need for your project, then mini substations are definitely worth considering.
Just like transformers, electrical substations have different types as well based on their performance, rating, category, components, classification, etc.
When it comes to the different types of mini substations, the types below can also be available for them.
Transmission substations are commonly for their ability to integrate transmission lines that is specifically assigned to a specialized network.
In terms of its connections, it has numerous parallel interconnections with it.The purpose of this is to let electricity flow freely over long distances from any generator to its consumer.
The transmission grid is also known as a bulk power system, and this lets transmission lines operate at voltages that are more than 138 kV.
It is also expected that transmission substations are commonly associated with a transmission from one transmission voltage to another level.
The main function of transmission substations is to transmit bulk power from sources of desirable generations to a specific delivery point.
For instance, from the area of the transmission substation to houses and other buildings from areas that are several kilometers away.
The benefits of this include but are not limited to: low electrical energy cost, better access to renewable energy, i.e., wind and hydro, better location for plants (away from populated areas), and better access to alternative generation sources (this is in case if the primary source is not available).
Distribution substations normally operate at 11 kV or 0.4 kV voltage levels, and they deliver electric energy that is direct to industrial and residential consumers.
Keep in mind that the distribution voltage level can vary in each country.
In terms of the location of the consumer, distribution transformers will be responsible for transforming the distribution voltage to service levels.
This is so that the households and industrial plants will be around 230 volts or 400 volts.
Basically, mini substations or miniature substations are like regular substations, but their transformer is expected to be smaller with a less kilovolt-ampere rating.
It has less when it comes to secondary distribution equipment such as breakers, switchgear, and other components.
Furthermore, it has a system that is less sophisticated, and it is able to protect the transformer and feeders.
This also includes metering and other controls as well.
The main purpose of a mini substation is to step down or decrease high voltage levels to low voltage levels for distribution.
In simpler terms, this is to make supplying electricity easier to distribute to houses and other buildings through the distribution lines that are connected with it.
Mini substations are expected to smaller with a lesser power rating compared to typical substations, but this does not mean that they are no longer worth considering, because they are still functional and they still have the main components such as:
When it comes to the mini substation’s insulator or cooling medium, its main function is to regulate the temperatures of the entire device.
Moreover, this component is also capable of being utilized as maintenance for the bus-bar system.
Insulators are also used to separate two types like post-type and bushing-type.
A post-type insulator is compromised of a ceramic body, and the cap of the insulator has a design that comes with a cast iron material.
Furthermore, it is directly connected to the bus bar as well.
There is a second type of insulator that is called a bushing that includes a ceramic body shell, a high locating wash, and as well as a bus bar that is in the appropriate position.
Due to the spike of trends in technology, it is no surprise that the installation of mini substations has also advanced in certain aspects.
A clear example of this is the supervisory control and data acquisition or also known as S.C.A.D.A.
This is an automation that made it achievable for controlling an electricity substation.
Moreover, it is basically designed to be settled in a far location.
A wave-trapper is responsible for alerting the mini substation from high-frequency signals. Moreover, it is also capable of redirecting the alert to a specific telecom board. This component can be found on lines that are incoming, and these lines trap the signal that is of high frequency.
In terms of where the signal is coming from, they are from remote stations, They too are able to interrupt or change the current and voltage signals.
The lightning arrester is considered the first component in an electrical substation, the lightning arrester’s purpose is to provide the other components security.
It gives them security when a sudden high voltage and amplitude of current occurs through the diversion of the current flow that is connected to the ground.
This way, the conductor of the system and the insulator will not be affected.
Mini substations are expected to smaller with a lesser power rating compared to typical substations, but this does not mean that they are no longer worth considering, because they are still functional and they still have the main components such as:
Chances are, you might have already heard about circuit breakers, and yes, mini substations have this as an electrical component and protective device.
The function of circuit breakers in mini substations is to be in the position of an electrical switch to turn on or turn off the circuit in the case that there is an emergency or fault in the device.
In a normal setting for mini substations, the two moving parts will be closed, and when there is an error, the component will signal or alert the circuit breaker of what is happening. This makes the parts isolated separately, making errors clear.
However, there are cases that the isolator is used to break the current, which charges the line of transmission.
The isolator is basically another type of electrical switch that is primarily used to isolate the circuit whenever there is a current that is being disrupted. These switches are also labeled as disconnected switches, and it operates in a no-load condition.
Isolators are also not in-built by arc-quenching apparatuses, and they also do not have any specific current-making or current-breaking limits.
Another protective component of mini substations is the protective relay, and its purpose is similar to a circuit breaker, which is to provide security to the mini substation as it is operating.
However, its difference is that the protective relay focuses on providing a shield for the grid component from faults and other irregular conditions.
This type of detecting device can also be used a measure to know where are the possible fault locations.
Since it is associated with a circuit breaker, it is expected that it will be responsible for sending the signal to it as well.
After the circuit breaker receives the notification, it will then proceed on detaching the damage part.
This component is very useful for protecting devices from hazards and damages.
The bus bar is considered to be one of the most important components in a mini substation, this is because it is a kind of conductor that carries currents, wherein the connections are being made.
The bus bar is also a device that can be considered as an connection device that came from a current that is either going or outgoing.
During the case of a fault, it is expected that the circuit components will be linked to the section, and normally be activated to give the device the right amount of isolation in just a short amount of time.
This will then deflect the fault since it can detect that the conductor’s temperature are starting to rise.
For large power stations like substations or power stations, relay systems, control circuits, operation of lightning, and others, this will require batteries because these electrical devices are connected to a battery that is linked to an accumulator cell that is dependent on the voltage of the circuit that is direct current (D.C).
A switchyard is basically an integral connector for transmission and generation.
An equal voltage is expected to part of the process, and during this process, the switchyard will be responsible for maintaing it.
Another function that switchyards are capable of is that their ability to transmit power that is coming from the mini substation.
The process of transmitting it will be provided through the right levels of voltage that is within the vicinity or transmission lines and power stations.
If you have a project that is an area that does not have the luxury of space, then there is without a doubt that mini substations can provide you with all the help you need with only a little consumption in terms of space.
Furthermore, the mini substation specifications are already enough to provide your small to medium projects with sufficient electricity. However, just keep in mind that the rating of mini substations and regular substations have a significant difference.
