Abstract :
In the last years, the low voltage loads in the distribution networks are changing due to the massive introduction of computers, air conditioning equipment and many other household appliances. This high frequency capacitive loads and some other factors like ground faults in the LV network, connections/disconnections in the MV network, etc, sometimes provoke transient overvoltages that ends up in a wrong tripping of the domestic electrical differential protection. This domestic outage is really annoying for our customers and sometimes can cause serious problems.
