what will happen when a bulb s connected btwn two phases of
a three phase delta connected source?
Answer Posted / sachin
As per our system, Vtg between two phases is 415V.so bulb
glows brightly for sometimes after that it may be blow-out
due to high vtg.
The reason, bulbs are specially designed for 230V AC.
