All work to be performed, from routine testing to adding entirely new substations, should be done while keeping the whole system running.

Designing of HV Power Substation and Layout

The kV level is eliminated for grid simplification. Unplanned switching events are caused by a fault in a transmission line or any other component, for example: The function of the 400 kv substation layout station is to isolate the faulty portion of the system in the shortest possible time.

De-energizing faulty equipment protects it from further damage, and isolating a fault helps keep the rest of the electrical grid operating with stability. Traction substation Electrified railways also use substations, often distribution substations.

In some cases a conversion of the current type takes place, commonly with rectifiers for direct current DC trains, or rotary converters for trains using alternating current AC at frequencies other than 400 kv substation layout of the public grid.

Sometimes 400 kv substation layout are also transmission substations or collector substations if the railway network also operates its own grid and generators to supply the other stations. Mobile substation[ edit ] A mobile substation is a substation on wheels, containing a transformer, breakers and buswork mounted on a self-contained semi-trailermeant to be pulled by a truck.

Electrical substation

They are designed 400 kv substation layout be compact for travel on public roads, and are used for temporary backup in times of natural disaster or war. Mobile substations are usually rated much lower than permanent installations, and may be built in several units to meet road travel limitations.

It has a facade in clay brick with grey stone ornaments, to blend into its downtown environment. Elements of a substation[ edit ] Substations generally have switching, protection and control equipment, and transformers. In a large substation, circuit breakers are used to interrupt any short circuits or overload currents that may occur on the network.

Smaller distribution stations may use recloser circuit breakers or fuses for protection of distribution circuits. Substations themselves do not usually have generators, although a power plant may have a substation nearby.

Other devices such as capacitors and voltage regulators may also be located at a substation. Substations may be on the surface in fenced enclosures, underground, or located in special-purpose buildings. High-rise buildings may have several indoor substations.

Indoor substations are usually found in urban areas to reduce the noise 400 kv substation layout the transformers, for reasons of appearance, or to protect switchgear from extreme climate or pollution conditions.

A grounding earthing system must be designed. The total ground potential riseand the gradients in potential during a fault called touch and step potentials[6] must be calculated to protect passers-by during a short-circuit in the transmission system.

PRESENTATION ON SUBSTATION DESIGN

Earth faults at a substation can cause a ground potential rise. Currents flowing in the Earth's surface during a fault can cause metal objects to have a significantly different voltage than the ground under a person's feet; this touch potential presents a hazard of electrocution.

Where a substation has a metallic fence, it must be properly grounded to protect people from this hazard. 400 kv substation layout
