Transmission lines are generally delta connected, hence they
don't have neutral wire.They are generally of two types
Single Circuit, Double Circuit lines.Single circuit consists
of 3-Phases R,Y,B.Double Circuit just consists of 2 Single
circuit lines.For economizing the cost of transmission lines
it is tried to use as many Double Circuit towers as land
cost to build these towers are increasing day by day.Even 4
circuit towers are also in use at places which have 4x3=12
conductors.Above stands for 33KV,132KV & 220KV transmission
lines. The conductors used are ASCR(aluminum Conductor steel
reinforced) or AAAC(All aluminium alloy conductor).
For 400KV lines each phase consists of 2conductors generally
known as bundled conductors (ACSR/AAAC -Moose variant)i.e
total 6 conductors for Single ckt., 12 conductors for Double
Ckt.

Generally HV transmission lines are like SUSPENSION towers they are very high cost to transmit the supply, In that case it is good to put 6 conductors and also if u saw that means it is generally construct like that on each side with porcelian insulators hanging with conductors....I think the conductor use the HV transmission lines are ACSR-Aluminium conductor steel reinforced....

A 100KVA SINGLE PHASE TRANSFORMER 10000/200V,50HZ REQUIRES 300V AT HV SIDE TO CIRCULATE FULL LOAD CURRENT WITH LV SHORT CIRCUITED.THE INTAKE IS 1000W.THE % OF REGULATION ON FULL LOAD AT 0.8 PF LAGGING WILL BE HOW MUCH AND THE SECONDARY TERMINAL VOLTAGE ON 0.8 PF LEADING WILL BE

how we control automatic generator i'e with to supply (main supply and local generator) when the main supply was break to supply the local supply automatically to begin supplying power.I now this control circuit is the combination of contactor time delay contactor switch and overload relay .but my question is how we combine those component thank you

Hello, im taking an introduction to PLC..and i'm having a hard time on creating a program for 2 lamps blinking alternately with this button characteristics: 1.) One push button (starts upon pressing) 2.) Same push button (when pressed again, will pause the system) 3.) Same push button (when pressed again, will continue the paused system) 4.) Same push button (when pressed within 2 seconds, will shut off the system) Pls..i know this is just a simple problem for you guys..
