Abstract
A method of increasing the sensitivity of protection from singlephase shortcircuits to ground by acting on the signal with brief dummy grounding of the neutral is described After determining the damage the neutral is again grounded through a high resistance and an arcquenching reactor An increase in the protection sensitivity is thereby obtained the damage detection time is shortened and the probability of the singlephase shortcircuit to ground converting into double and multipoint earth faults is reduced
