What about the electrical circuits used in Indian railways to drive a train?
using 25KV
Where is the neutral for 25kv ac single phase supply used for electric locomotives?
from ground
Is china's crh2 a maglev?
Nope - according to the Wikipedia entry - it's supplied by 25KV AC overhead electric wires.
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
How many voltage supply is used for Indian railways?
Voltages used are 1.5kV DC and 25kV AC for mainline trains
How many volts do the transperth trains use?
Transperth EMU (Electric Multiple Unit) Traction voltage is at 25KV AC, The current that runs though the train is quite the mystery tho :PHope this answer wasn't too late for you :)
Why railway used 25 kv system?
25kV is used with 50Hz systems, and 15kV is used with 16 2/3 Hz systems. With higher frequency the power lines have higher impedance and you need higher voltage to transfer energy.
What is a Booster Transformer in Railway Engineering?
A booster transformer is a 1:1 ratio transformer. They are mounted on overhead line structures, with the primary side attached to the contact system and the secondary side attached to the return conductor. The 25kV voltage on the primary side induces a 25kV voltage into the return conductor which helps reduce electromagnetic interference with other electrical equipment namely signalling and telecomms.In the UK there are two common types - breathable which were installed with the first major electrification program, and sealed which are used to replace the old transformers.Manufacturers include Alstom and ABB.Weights are in the 2800-3050kg range.All transformers are oil filled.
How calculate kilovolt-ampere?
25kv=?kwAnswerA volt ampere (V.A) is the unit of apparent power, and applies to AC circuits that contain resistance and reactance. Apparent power is the vector sum of true power and reactive power. A kilovolt ampere is 1000 V.A. The volt ampere is the product of supply voltage and load current.
What are uses of electricity in transportation?
The main use of electricity in transportation is traction. The use of motors to drive trains, trams and trolley buses. Transmission system vary depending on their use, vintage and country. Direct current (600 -3000V DC) overhead current collection used on tramways and railways. Conductor rail (600-750V DC) are used mainly on rapid transit and underground (subway) rail systems. Except in the United Kingdom where it is used on some main rail lines in southern England. High voltage alternating current (11-25kV AC) overhead transmission. 11kV 60Hz used in the US; 15kV 16 and two-thirds Hz used in Germany, Austria, Switzerland and the Scandinavian countries; 25kV (50 or 60Hz depending on the country) developed in France after WWII and used extensively throughout the world in countries as diverse as China (50Hz), the US (60Hz), UK (50Hz) and India.

Explain the transmission and distribution of electricity from the generation station to the consumer?
transmission and distribution of electricity are the way of regulate voltage to the minimum rate in which can be benefit to the consumers. From generating station , voltage generated is up 16/25kv which step up upto 330kv this generating voltage now step down in the transmission station through the step down transformer which is 132kv this voltage now transmitting to distribution station where voltage now step down to 33kv, this 33kv now stepdown to 415v for three line and 240/220v for a line for the uses of consumers.
