How to move from one phase to another?
Good evening, I want to ask you: at my place two phases are stretched from different lines and sometimes these lines are cut down, in another phase the voltage is low. Which autotransformer do I need to install and which thyristor or triac must I install to switch from one phase to another?
I recommend setting the switch between phases, a reversing starter. This device eliminates the simultaneous supply of phases. Choose a stabilizer on a budget, 7 kW is enough for an apartment
