Sentence examples for a protected line from inspiring English sources

When a fault occurs in a protected line, the impedance trajectory enters in distance relay zones and the relay operates.

The distance protection can protect most of the protected line, and it is virtually independent of the source impedance.

Any fault in the direction of the protected line from a breaker is defined as a forward fault and a fault on the bus side from a breaker is defined as a reverse fault.

Thus upon reception of the directional signal from R43 at the other end, occurrence of a fault in the protected line was confirmed.

Therefore: 1) the peak |dv/dt| observed at the line side of terminal inductor is much greater than that observed at the bus side when the voltage wave is initiated from a fault on the protected line.

Since the fault generated voltage surge attenuate when passing through a di/dt limiting inductor, the peak dv/dt observed at the line side of terminal inductor is significantly smaller for bus faults and the faults in the adjacent lines, compared to the peak dv/dt observed for a fault in the protected line.

2) the peak |dv/dt| observed at the line side of terminal inductor is much smaller than that observed at the bus side for faults on the bus or lines behind the inductor location.  . the peak |dv/dt| observed at the line side of terminal inductor is much greater than that observed at the bus side when the voltage wave is initiated from a fault on the protected line.

This criterion can be used to distinguish whether a fault is on its protected line.  .

The concept of a protected reference line (or reference user) is introduced in these papers as a statistical average of all victim lines suffering interference.

A dependable DC line protection scheme should be capable of detecting a fault at any point on the protected line regardless of the fault resistance.

Please note that the protected line of the remote backup protection is adjacent to the neighbor element and the state of this line, the previous operation result of the other protection (main protection) and the relevant remote backup protection are all related with the remote information.
