Coexistence of TN and TT Systems
There is a need to connect the adjacent LV distribution networks for the purpose of emergency power supply or for the duration of maintenance and repair. If these networks are different, e.g. TN and TT, they may not always be directly connected. The paper presents possible solutions in several real situations indicated by readers.
