Sentence examples for collector lines from inspiring English sources

The reactive power loss in collector lines consists of line equivalent reactance and equivalent admittance.

The loss comes from unit transformers, main transformer and collector lines.

If the protection zone I of the fault collector line fails to operate, the protection zone III of the non-fault collector lines may act to trip off all the connected wind turbines.

Magnetic fields measured 1 m above buried collector lines were also within background (≤ 0.3 mG).

For the third scenario ('shut off'), measurements were collected when the turbines and associated collector lines were powered off completely.

Magnetic fields were also measured immediately above the buried 27.5 kV collector lines associated with each of the wind turbines included in the study.

Thus, the collector line current protection zone I setting values can be shown as below.

The analysis shows that when the fault occurs, the protection zone I of collector line 1 can remove the fault instantaneously.

Furthermore, in order to solve the time incoordination problem between the collector protection I and the fuse, the difference of the fault occurred at the high voltage side of the turbine transformer and the collector line should be distinguished.

On the contrary, when the fault occurs in the collector network, the fuse current is smaller than the protection setting value of the corresponding collector line and the current increases with the decrease of the distance from the fault point to the bus.

~ 0. In order to realize the perfect match between the collector line current protection zone I and the fuse, a short time delay is added to the collector network current protection zone I. Figure 9 shows the improved action curve of the PMSG low voltage protection.
