The higher-voltage line will have longer insulators and the line conductors will be further apart. And the symbol for kilovolt is 'kV', not 'kv'.
ht cable that means voltage level is high , it is obvious that power is going to remain same ,so if voltage rises ,current has to be lowered .since current level is less in ht cable therefore size (dia) is less compared to l.t cable , (p=v.i),lt cable current rating is more and voltage rating is less
The length of the wire causes resistive load to be distributed along line. This accumulated resistance causes the voltage drop.AnswerThe voltage drop along a high-voltage transmission line isn't large in relation to the operating voltage of the line. One of the advantages (there are many) of using high voltages is that, for a given load, the line current is relatively low -so the voltage drop along the line is also relatively low.
An isolator (disconnector in US terminology) is a switch designed to isolate a section of line afterthat line has been de-energised using a circuit breaker, allowing maintenance work to be carried out on the de-energised section.It's function is to provide a visual break between an energised line and a section of de-energised line and, therefore, is usually one of a pair (one at opposite ends of the de-energised section).Isolators are generally not designed to break load currents (and definitly NOT fault currents!!), so the line must be de-energised using a circuit breaker before the isolator is opened, and the isolator must be closed before the circuit breaker is then used to reclose the line.
The main use for a wind turbine is to drive a geared alternator mounted at the hub of the rotor. The blades rotate at some speed around 29 rpm, and that is stepped up in a gearbox to drive the generator at a more normal speed for an electric generator. The output power is fed to the local distribution grid, at 33 kV for the smaller wind farms or 132 V for the larger ones.
Actually ACB isused for Low Tension side and VCB is used for High Tension Side..Chappa matter
The safety distance from a 132 kv powerline is 1.4 metres
The difference between 309 and 132 is 177 numbers.
|32 - 132| = |-100| = 100 |32 - 132| = |-100| = 100
40,074,642,432
-132
1127
Yes, 132 miles of it.
132 accur. 150 power
2 to the 3rd power
8 to the 10th power
1322 = 17424
132 because if you line them up on a pice of paper and you add down you will get 132
