What is difference between substation and transformer?
AnswerIt is a large encased group of metal plates about the size of a small house with 2 sets of insulated copper wires wrapped around the plates -an input and output - to convert a very high supply line voltage - maybe 44 thousand volts to a lower voltage of 2200 volts that runs down the power line poles in your neighborhood. Look at your street's power poles and you will see a mini substation that converts he 2200 volt to 220 volts and may supply several homes. Actually a substation transformer for a distribution substation will reduce the incoming voltage from 115,000 volts or 69,000 volts to a lower voltage closer to 7200 volts that runs down the power poles in your neighborhood. At your house there will be a small transformer that reduces the voltage from 7200 volts to 240 volts to meet the needs in your home.Actually both are wrong !!
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.
What types of transformers used in 220 kv double bus switch yard?
We use double rating transformer, in this we have two type of cooling . ONAN & ONAF, According to cooling we have two rating.
What is the function of capacitor voltage transformer at the switch yard?
function of capacitive voltage transformer is measure high transmission voltage with low range voltmeter and oprate the relay circuit to oprate CBs.
What engineering jobs starts with y?
Yard Engineer (railroad) is an engineering job. It begins with the letter Y.
When was Concourse Yard Substation created?
Concourse Yard Substation was created in 1933.
What is the difference between a switch yard and a substation?
the switch yard consist of the buss, breakers and switches. where as when you add step up or step down transformers with or with out LTC'S (load tap changer).
Design of earthing calculation 132 kv switch-yard?
Refer IEEE 80- 2003 For Design of grounding of 132kV substation.
What is green field substation?
In my line of work that is an Electrical High Voltage substation that is brand new. It is being built from a green field into an energized fully functional substation yard. There is no existing substation or remodeling of an existing one being done.
Are a meter and a yard the same thing?
no.
Is a baseball diamond in a ball yard?
Yes, a diamond and a yard are considered the same thing.
Are meter sticks and yard sticks the same size?
If they were, we wouldn't need two names for the same thing. 1 yard = 0.9144 meter 1 meter = 1.0936 yard
What 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.
