It can delicer leading current with the current exchange in coupling reactor and the controlling of the switch on off phase angle in order to compensate lagging reactive power.
The coupling of current, temperature and stress has been proposed in crack arresting by the electromagnetic heat effect at the moment when a pulse current is switched on.

Electrical couplings promote the passage of certain signals but prevent the passage of others, such as an alternating currentcoupling that excludes direct current.
