Circular indenter PFVL141C

 

Parallel lines introduce an error in the measurement due to the mutual coupling between the parallel lines. The lines need not be of the same voltage level in order to experience mutual coupling, and some coupling exists even for lines that are separated by 100 meters or more.

The mutual coupling does influence the zero sequence impedance to the fault point but it does not normally cause voltage inversion. It can be shown from analytical calculations of line impedances that the mutual impedances for positive and negative sequence are very small (< 1-2%) of the self impedance and it is a common practice to neglect them. From an application point of view there exists three types of network configurations (classes) that must be considered when making the settings for the protection function.

The different network configuration classes are:

1. Parallel line with common positive and zero sequence network

2. Parallel circuits with common positive but isolated zero sequence network

3. Parallel circuits with positive and zero sequence sources isolated.
