If you work in or around the electrical power industry, then you know that substation equipment is a vital part of the system. Sure, generating stations and transmission lines get all the attention, but without substations, the electricity wouldn’t be able to get where it needs to go. In this blog post, we’ll take a detailed look at substation equipment and how it works to keep the power flowing.
Substations come in a variety of shapes and sizes, but they all have one thing in common: they house electrical equipment that transforms or switches electricity from one voltage to another. This equipment includes transformers, circuit breakers, switchgear, and more. Let’s take a closer look at each of these components.
Transformers are perhaps the most important piece of equipment in a substation. They step up or step down voltage as needed so that electricity can flow through transmission lines at different voltages (e.g., 115 kV vs 345 kV). Circuit breakers are also critical; they protect against overloads by automatically disconnecting circuits when there is too much current flowing through them.
Switchgear is used to physically connect and disconnect circuits; it typically includes switches, fuses, and other devices.
In short, substation equipment is essential for the safe and efficient operation of our electrical grid. Without it, we wouldn’t be able to enjoy the many benefits that electricity brings us every day!
Substation Equipment Names
Substation Equipment Names
As you probably know, a substation is an electrical installation that provides equipment for the distribution or transmission of electric power. But did you know that each piece of equipment inside a substation has a name?
Here are some common substation equipment names and their functions:
• Transformer – increases or decreases the voltage of an alternating current (AC)
• Circuit breaker – breaks an electrical circuit to prevent damage from overloads or short circuits
• Disconnect switch – safely disconnects electricity from equipment when it needs to be serviced or replaced
Substation Parts And Equipment
Substation equipment is used to control, protect and monitor the operation of electrical power systems. It includes a variety of devices such as circuit breakers, transformers, relays, and meters.
Circuit breakers are one of the most important pieces of equipment in a substation.
They are used to interrupt the flow of electricity in the event of a fault or overload. The breaker must be able to open and close quickly enough to prevent damage to the system.
Transformers convert high-voltage electricity into low-voltage electricity or vice versa.
This is done by changing the magnetic field strength within the transformer coils. Relays are used to activate or deactivate circuit breakers or other devices remotely. Meters measure various parameters such as voltage, current, and power factor.
Substation equipment must be designed for both indoor and outdoor use. It must be able to withstand extreme weather conditions and vibration from nearby machinery.
Transformer Equipment List
A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction. A varying current in one coil of the transformer produces a varying magnetic flux, which, in turn, induces a voltage across a second coil wound around the same core. Electrical energy can be transferred between the two coils, without direct electrical connection between them.
Faraday’s law of induction describes this process.
Transformers are used to increase or decrease the alternating voltages in electric power applications. Several types of transformers are used in electronic equipment:
The most common type of transformer used in electronic equipment is the AC power transformer. These transformers step up or step down the voltage from the AC power line to provide proper voltages for the various stages of electronic equipment. For example, an audio amplifier may use a 120 VAC input and provide ±15 VDC for its internal circuitry; thus it would require a transformer with a turns ratio of 8:1 (120 ÷ 15).
The primary winding would be connected to 120 VAC and the secondary winding would be center-tapped so that there are two output connections: one at +15 VDC and one at -15 VDC. The number of turns on each winding must be proportional to its voltage so that equal currents flow through both windings when carrying equal loads; hence, 8 times as many turns are required on the primary side as on the secondary side. If we assume that each winding has 1000 turns, then there must be 8000 turns on the primary (8 × 1000) and only 1000 turns on the secondary.
Most AC power transformers have several secondary windings so they can provide different voltages from a single input voltage; for example, a “triple” secondary might have three separate outputs: +15 VDC / 0 VDC / -15 VDC (center-tapped), while a “quad” secondary might have four outputs: +12 VDC / +5 VDC / 0 VDC / -5VDC (also center-tapped). Audio output transformers sometimes have multiple primaries so they can match different impedance levels from tube amplifiers; for example, an output transformer might have two primaries rated at 3kΩ and 6kΩ respectivelyto match two different impedances from push-pull vacuum tube amplifiers operating in parallel mode..
Substation Equipment Ppt
Substation equipment is essential for the safe and reliable operation of the electrical grid. This equipment includes transformers, circuit breakers, and other devices that help to regulate the flow of electricity. Substation equipment must be carefully maintained and operated in order to ensure the safety of those who work with it and the public.
33/11Kv Substation Equipment Pdf
In any electrical power system, the heart of the distribution network is the substation. A typical 33/11kV substation equipment comprises a primary switchgear, secondary switchgear, instrument transformers, control and protection devices etc. The primary purpose of a substation is to take high voltage from the transmission system and distribute it at lower voltages to feed loads or for further distribution.
The first stage in any substation is the primary equipment which receives energy at very high voltage levels from transmission lines. This energy has to be stepped down to lower secondary voltages before it can be used by consumers. The most common way of doing this is by using transformers.
Transformers change the voltage level by magnetic induction between its winding without any physical contact between them.
Secondaryswitchgear takes energy from primary switchgear at a lower voltage and uses it to feed loads directly or for further distribution at an even lower voltage level. In many cases, bothprimary and secondary switchgear will be contained within the same building though this is not always necessary.
Instrumenttransformers are used to measure currents and voltages in a circuit without disturbing normal operation. They are essential in providing accurate readings for protection devices so that they can function properly.
Protectiondevices are installed in all electrical systems as a safety measure.
Their main purpose is to automatically disconnect parts of the system in case of faults so that damage can be minimized.

What are Main Components of Substation?
Substation is a power plant where electricity is generated and then transmitted to a grid. The main components of substation are:
1. Transformers – Transformers convert high voltage electricity from the power plant into low voltage electricity that can be safely used in homes and businesses.
2. Circuit breakers – Circuit breakers protect electrical equipment from damage by interrupting the flow of electricity when there is a problem.
3. Capacitors – Capacitors store energy and help regulate the flow of electricity through the substation.
4. Inductors – Inductors help to stabilize the voltage in the substation and improve the quality of the electricity being transmitted.
What are the Three Main Components of a Unit Substation?
The three main components of a substation are the primary equipment, the secondary equipment, and the tertiary equipment.
The primary equipment includes the transformers, breakers, and busbars. The secondary equipment includes the current and voltage transformers, relays, and meters.
The tertiary equipment includes the control panel, power supply, distribution panels, and cable glands.
Which is the First Equipment Installed in Substation?
The first equipment installed in a substation is typically the high-voltage switchgear, which includes the circuit breaker that will be used to interrupt the flow of electricity in case of an emergency. This switchgear is usually located in a separate room from the rest of the substation equipment, for safety reasons. Other equipment that may be installed at this time includes low-voltage transformers and control panels.
