What is gantry substation?

Gantry structures are mainly used for guiding the power conductor from last tower near substation to the electrical equipments in a substation. This structure consist of a number of columns and Girder beams, which depend on number of circuits of the line. Gantries are also used for line crossing.

What is the difference between a substation and a switching station?

An electrical substation is typically a secondary station connected to an electrical distribution, generation or transmission station. A switching station is a particular type of substation where energy is routed either from different sources or to different customers.

What is the difference between incomer and feeder?

Incomer means incoming supply source for the substation. Feeder means outgoing supply to designated area/village where the electrical supply is to be distributed. In industrial company feeder means the outgoing g supply to some of the major auxliary electrical equipment.

What are the three types of substations?

The different types of substations mainly include Step-up Type Substation, Step-down Transformer, Distribution, Underground Distribution, Switchyard, Customer Substation, and System Station.

What is a gantry used for?

Full gantry or semi-gantry cranes are commonly used for heavy fabrication applications, or in some type of outdoor yard—rail yards, shipping and container yards, steel yards, and scrap yards. They’re also very popular for cement and precast applications for areas where they’re forming and curing slab concrete.

What is substation layout?

The substation is the part of an electrical supply system which transmits the high voltage from the generating substations to the local distribution networks. Between the generation and distribution, the voltage may vary through several substations.

Why is substation needed?

To step up or step down AC voltage using transformer(s) Voltages at the distribution end need to be stepped down for utilization by customers. Substations provide the necessary real-estate to install a transformer for power transmission and distribution.

What is Incomer circuit?

Common. The term Incomer refers to the materials used between the supply cable and the busbars. The incomer is most commonly comprised of the switchboard’s main switch, measurement instruments and protection devices.

What is the difference between substation and grid station?

An electrical power substation is a conversion point between transmission level voltages (such as 138 KV) and distribution level voltages (such as 11 KV). An electrical grid station is an interconnection point between two transmission ring circuits, often between two geographic regions.

How many volts are in a substation?

Substations: The electricity in homes is typically 120 volts (1 kV = 1,000 volts). When electricity moves from transmission lines to subtransmission lines to distribution lines, the voltage must be “stepped down” by transformers.

What’s gantry mean?

Definition of gantry 1 : a frame for supporting barrels. 2 : a frame structure raised on side supports so as to span over or around something: such as.

What is the function of switching substation?

switching substation is a substation which does not contain transformers and operates only at a single voltage level. Switching substations are sometimes used as collector and distribution stations. Sometimes they are used for switching the current to back-up lines or for paralellizing circuits in case of failure.

What is a switching station?

What is a switching station? A switching station is a substation that does not contain power transformers and therefore does not change system voltage from one level to another. Switching stations usually operate at sub-transmission or transmission voltage levels.

What type of equipment is used in a power substation?

The focus is in mineral oil-insulated (oil-immersed) three-phase units, which form the majority of distribution power transformers in applications under IEC influence. Circuit breakers which control high voltages and protect other substation equipment are also located at power substations.
