What is substation and its components?

The electrical power can be transmitted from the units of generation to distribution using various electrical substation components namely isolator, bus bar, power transformer, etc are connected together in the substation. The electrical substation components are essential for installation of the substation.

What are the accessories of pole mounted substation?

Pole mounted substation

  • A single pole mounted MV/LV power transformer that is, according to the local rules associated or not with: A load break switch. A set of three fuses. A set of three surge arrestors.
  • A low voltage circuit breaker.
  • An earthing electrode realized at the bottom of the pole supporting the equipment.

What equipment is in a substation?

Distribution Transformer. Circuit breaker. Lightning Arrester. Air Break (AB) switches / Isolator.

What is inside the substation?

The compartments of such substations take the form of metal cabinets or enclosures, each of which contains the equipment of one main connection cell. In such cabinets, an oil circuit breaker, a load interrupter switch, and one or more voltage transformers may be mounted.

What are the three main parts of substation?

Elements of a Substation

  • Primary power lines.
  • Ground wire.
  • Overhead lines.
  • Transformer for measurement of electric voltage.
  • Disconnect switch.
  • Circuit breaker.
  • Current transformer.
  • Lightning arrester.

Why pole mounted substation are very popular?

Pole Mounted Substation Such substations are used for supporting distribution transformers having the capacity up to 250 KVA. Lightning arresters are equipped over the high tension line for the protection of the transformers from the surges. Pole-Mounted substations are earthed at two or more places.

What is pole mounted substation explain with diagram?

It is a distribution sub-station placed overhead on a’ pole. It is the cheapest form of sub-station as it does not involve any building work. Fig 25.2 (i) shows the layout of pole-mounted sub-station whereas Fig.

How are substations classified?

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

What type of transformer is used in substation?

1. Substation Transformers. Used with outdoor substations, they are rated 750-5000 kVA for single-phase units and 750-25 000 kVA for three-phase units. High voltage transformer 40MVA (Steps down 150kv to 10kV in a substation in Belgium.

What is the purpose of a pole mounted substation?

A Pole Mounted Sub-station is a large, free standing, outdoor electrical equipment that is mostly located in residential places. Its main purpose is to step-down the lethal 11kV to 415/240V for light, commercial and residential loads (consumers)… The 11kV line is connected to the Step-Down Transformer (11kV/415V)…

What are the components of an electrical substation?

1 Instrument Transformers: 2 Current Transformer: 3 Potential Transformer: 4 Conductors: 5 Insulators: 6 Isolators: 7 Busbars: 8 The Lightning Arresters: 9 Circuit Breakers: 10 Relays:

How are power feeders connected to the substation?

Basically, the connection is with a bus of the substation for carrying power from the substation to service points. The feeders can hug overhead streets, underground, underneath streets, and are carrying electrical power to that of distribution transformers at near or farther premises.

Why do you need a single line diagram for a substation?

Single line diagrams are useful in planning a substation layout. Some of the standard symbols used to represent substation components are given in Table below. Power transformers: Power transformers are used generation and transmission network for stepping-up the voltage at generating station and stepping-down the voltage for distribution.
