Data center substation is among the special types of substations, which are specially designed for highly reliable, high power quality, and uninterrupted power supply to critical IT processes in the data center. These substations stress majorly on the importance of redundancy of power supply with reliability to various …
A substation technician is a skilled professional who helps the engineer with the installation, testing, operation, and maintenance of the substation equipment. The substation technician, along with the engineer, makes sure that the substation operates efficiently and reliably. The critical substation equipment requires continuous monitoring, such as the …
A single-line diagram or substation SLD represents three phases of a power system by a single line, showing the arrangements of different electrical equipment in the switchyard. It shows how the generator, transmission line, circuit breaker, wave trap, capacitive voltage transformers, current transformers, etc, are interconnected with the …
An Electric substation is a part of the power system, which is utilized mainly for the transformation of voltage, either stepping up or down, depending upon the type of substation, either a generation substation or a transmission substation, respectively. Main electrical equipment of a substation The main electrical …
Substation SCADA (Supervisory Control and Data Acquisition) is basically a system of certain hardware and software through which monitoring, analysis, and control of a power system can be achieved remotely. The data is acquired from the field equipment, transmitted to a central unit utilizing a communication network, which …
Renewable energy integration in a substation is the process of connecting the renewable energy-generating plants, like solar, wind, hydro, and biomass plants, to the electrical grid for the transformation and transmission of generated power. The renewable energy integration of the substation also refers to the substation being the …
A digital substation is a modern electrical substation, where the use of copper cable for communication between various conventional relays is minimal; rather, optical fiber is used for communication between circuit breakers, transformers, and IEDs (Intelligent Electronic Devices). The raw electrical signals used in older substations are replaced …
A mobile substation is a temporary arrangement of compact assembly of all the essential components of a power distribution system, mounted on a transportable platform. The setup of this type of substation is easy and quick, done primarily to provide emergency power to areas that cannot be conventionally …
Substation construction is the building of an electrical substation, which is an essential part of a power system that connects the transmission network to the distribution network or generation to the transmission network. Substation construction involves civil works for the foundation of various electrical equipment and the control …
Creepage distance is the minimum distance between two conductors (phase to earth or phase to phase) along the surface of the separating insulator. It is the surface leakage path that the leakage current will take across the insulator via its surface and not through air. As the path …
Insulation coordination is basically the selection of the dielectric strength of the equipment with respect to the operating voltage and the overvoltage stress it will be subjected to during the system operation, considering the environment and characteristics of protective devices. The objective of insulation coordination is to increase …
The minimum distance or gap that is required between two conducting parts, without causing any electrical flashover, is known as electrical clearance. Electrical clearance is a function of the implied voltage or potential difference between the two conductors. If the voltage between two conductors is more, then the …
Substation Layout is basically an orderly arrangement of electrical equipment based on function, safety, and security, considering several clearances and space constraints or availability of land for achieving better operational flexibility, security of power supply, maintenance flexibility, along with accounting for lower cost. A well-designed Substation layout offers …
A turnkey project involves a single contractor or EPC firm engaged for the entire project life-cycle, responsible for engineering design to construction, procurement, and commissioning, finally handing over to the asset owner as a ready-to-use facility. Here, the asset owner usually turns the key to start the operation. …
Site Selection of a Grid Substation The site selection of a Grid Substation is the first and most important activity. This needs meticulous planning, foresight, skillful observation, and handling so that the selected site is technically, environmentally, economically, and socially optimal and is the best suited to the …
Electrical Faults are abnormalities of electrical parameters, either voltage or current, or both in a stable power system. Electrical faults are generally caused by equipment failure, human error, and environmental conditions. Electrical faults can cause significant economic damage and have the potential to cause fire hazards risking human …
Bus bar The bus bar is a common conductor/group of conductors where all incoming and outgoing feeders connect. It collects the incoming electrical power and distributes it to the outgoing circuits. We can say it works on Kirchhoff’s current law. The bus bar is used at all voltage-level …
A GIS or gas-insulated switchgear substation is a compact, metal-enclosed structure that houses high-voltage switchgear, busbars, and other electrical equipment. Unlike conventional Air Insulated Switchgear (AIS) Substations, which use open-air configurations, GIS substations utilize sulfur hexafluoride (SF6) gas as an insulating medium within metal-enclosed units. This design not …
Air insulated Switchgear or AIS Substation is a type of substation where all electrical switchgear and other high-voltage equipment’s insulation to earth and between phase conductors are mainly provided by air at atmospheric pressure and where some live parts are not enclosed. Working Principle The basic working principle of …
Substations are part of an electrical power system which plays a very important role in the generation, transmission, and distribution of electricity. It serves as an intermediary point between the source and load distribution networks. The main functions of substations include voltage transformation, switching, and protection of the …
