Type of transformers used in gas insulated substation?
Current transformer and voltage transformer . This transformers are actually measuring instruments which measures the quantity of current and voltage coming out of the substation.
What is the current carrying capacity per pole of 3.5 core 300 sq mm xlpe cable?
according to manufacturers data sheet 325amps ,but plz tell me how to calculate current carrying capacity of a cable.
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.
How do you calculate the current capacity of a cable when the cable size is known?
The current-carrying capacity of a cable depends on a number of things in addition to its cross-sectional area; these include the type of conductor, number of cores, type of insulation, whether or not it is armoured, method of installation, etc. Accordingly, to determine its current-carrying capacity, you will need to refer to your national electrical code. For example, in the UK, BS 7671:2008 Requirements for Electrical Installations contains tables for all standard cable types, specifying current-carrying capacity, voltage drops, etc.
How do you measure resistance in substation?
As we all know, Transformers are majorly used in substations. Transformers are specified with their Copper loss & Iron loss impedance (similar to resistance in DC circuits) which are generally considered with AC supply. Therefore, we can calculate the total impedance byanalyzing the substation installation blue prints ORusing parameters Input voltage, currents & Output voltage current taking the whole substation as a single unit with the help of phasor diagrams. Here, you'll have to consider if the transmission is double circuited or else likewise.

How can calculate the current capacity of 2.5 sq mm wire?
You don't calculate the current-carrying capacity, you find out from the appropriate Tables in your country's wiring regulations. In the UK, this is BS 7671:2008 Requirements for Electrical Installation.The reason you must do this is that the current-carrying capacity of a cable depends on the conductor type, number of cores, the type of insulation, the method of installation, etc. Allthese factors are taken into account in these Tables.For a 2.5-mm2 copper cable, the current-carrying capacity can vary from around 22 A to around 36 A, depending on the factors described above.

What is the function of Batteries in the substation?
a very helpful functionAnswerBatteries 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.
