What are the types of faults in ehv transmission lines?
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
Why no electric shock from neutral line?
There is normally no voltage on the neutral line because the neutral line is grounded. However, and this is always important, do not assume that neutral is grounded, nor that there is not an elevated voltage on neutral or ground due to a possible ground fault.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
What are symmetrical and unsymmetrical faults?
the fault in electrical transmission line which give rise to symmetrical fault current is called symmetric fault. e.g; L-L-L-G fault. the fault in transmission line which give rise to unsymmetrical fault current is called unsymmetrical fault.e.g; L-L , L-L-G , L-G fault to solve the unsymmetrical fault, the fault current can be represented by sum of the sequences--zero phase sequence , +ve phase sequence , -ve phase sequence. where L:line G:ground
What is symmetrical fault in transmission line?
A symmetrical fault is a fault where all three phases are experiencing the same thing. This is also called a three phase fault, since all three phases are involved.
What is a breaking point in layers of the earth?
That sounds like you are looking for the word "fault" or "fault line".
What are the types of transmission line faults?
these are the faults that occur in transmission line: 1. line to line fault 2. line to ground fault-this is the most common fault that occurs in tr. line(75%) 3. double line to ground fault 4. triple line to ground (or) 3 phase fault- this is the most serious and dangerous fault that occurs in transmission line.(but rarely occurs)
What is the name of the Kobe japan fault?
The fault that caused the 1995 Kobe earthquake was the Nojima fault.
How can you fix a brake fluid leak when it's a leak in the brake line?
depends where the leak is. In the brake line or at the pump? electric or mech brakes? if its in the line you should be able to replace the line section
Where is the denali fault line?
The Denali Fault line is located in Alaska.
What fault line is San Francisco on?
San Andreas Fault Line
Peugeot 406 electric window fault?
The electric windows on a 406 might behave weird if you disconnect the battery. But holding down the "window-down" on drivers side for 10 seconds or so should fix it.
What is the name of the fault line in South America?
The San Andreas Fault is the fault line is South America.
How does a distance protective relay work?
The distance relay trips when a fault occurs at a distant or a remote place in the electric transmission line. There is a mechanism based on the impedance calculation of the distance of the transmission line after which it is accurately known where the fault has taken place. Thus the distance protective relay can trip the circuit & prevent the fault to be carried further and also can indicate the location of the fault.
What fault line did the Kobe earthquake happen on?
Kobe is on the nojima fault line
Is Jiegu China near a fault line?
It is a kilometer away from a fault line.
What are the types of faults in ehv transmission lines?
The three types are Line to ground faults line to line fault double line to ground fault three phase line to ground fault
