Power lines are conductors that are designed to carry large amounts of electricity. Inside substations, rigid bus is typically used instead of slack conductor, although jumpers to various pieces of equipment are used.

∙ 12y agoA "substation" is not a power generating plant but a facility that modifies incoming power and redistributes it to the grid. There are several reasons to do this,among these can be mentioned:
- Changing voltage (power is generated and transmitted at very high voltages which are successively transformed down until they reach final consumers)
- Phase correction (if alternating current from different sources are out of phase when they are combined they could destructively interfere with each other)

What should be the minimum recommended value of power factor of a substation?
A substation is not a load but is a place where switching and voltage-level changing takes place. Accordingly, you cannot apply a 'power factor' to a substation.
What is the classification of electrical power substation?
Pole mounted Outdoor
Why DC source is required for a breaker?
A high-voltage circuit breaker's trip coil is normally operated from a d.c. supply -provided by a bank of batteries located in the substation. This ensures that, in the event of a total loss of a.c. power to the substation, the protection system remains effective.
What is the difference between 220KV grid sub station and 132KV grid sub station?
An electrical power substation is a conversion point between transmission level voltages (such as 138Kv) and distribution level voltages (such as 11Kv). A substation has one or more step-down transformers and serves a regional area such as part of a city or neighborhood. Substations are connected to each other by the transmission ring circuit.A electrical grid station is an interconnection point between two transmission ring circuits, often between two geographic regions. They might have a transformer, depending on the possibly different voltages, so that the voltage levels can be adjusted as needed.The interconnected network of grid stations is called the grid, and may ultimately represent an entire multi-state region. In this configuration, loss of a small section, such as loss of a power station, does not impact the grid as a whole, nor does it impact the more localized neighborhoods, as the grid simply shifts its power flow to compensate, giving the power station operator the opportunity to effect repairs without having a blackout.AnswerA 'grid' station is a substation -i.e. a compound or building containing transformers, circuit breakers, busbar systems, and protection system. The correct term is a 'grid substation', which is simply a substation which is part of the grid system -i.e. the transmission system. Other substations include 'primary substations', which interface the transmission system with the distribution system, and 'distribution substations' which could be as simple as a pole-mounted transformer.
Function of dc battery at substation?
Batteries are essential components in a substation. They provide the (tripping) current by which protective relays can trip high-voltage circuit breakers in the event of a fault. This means that the circuit breakers can trip even if the substation itself has lost its ancillary AC power supply.
Where the rtus are placed in power system?
RTUs play a vital role in communication of signals and information between two stations in a Power system network. In a substation, all the signals and information of interest and importance are captured and transmitted to upstream substation using RTU. These are placed in control buildings of important substations.
What is pooling substation?
The Substation which comes power from the power plant know as pooling substation.
What is a mini-substation?
A substation that is smaller than the average substation. A substation converts electric power from one voltage to another.
When was Saskatoon Electrical System Substation created?
Saskatoon Electrical System Substation was created in 1929.
What is the main function of auxiliary transforme in a substation?
auxiliary transformer is used to supply low voltage for AC power system inside substation such as lighting ,air conditioners and other AC supply system and DC power system such as protection relays, batteries, SCADA & telecom system and other DC supply system
What is grid substation?
this type of substation are considered important because any sort of disturbance in these substation may lead to the failure of grid.this type of substation are used to transmit huge amount of power from one point to other point in the gridAnswerA substation is a location where electricity transmission/distribution voltage-levels are changed and switching is carried out, as opposed to a power station, where electricity is generated. A substation, therefore, is a yard/building in which there are transformers, switchgear, busbar systems, and protection systems.A grid substation is part of the electricity grid system -i.e. part of the transmission system. In the UK, this involves voltage levels of 400 kV, 275 kV, and 132 kV.
