Answer Posted / bharani
Whenever neutral fails in three phase system, the connected
loads will get connected between phases owing to floating
neutral.Hence depending on load resistance across these
phases, the voltage keeps varying between 230V to 400V.A
suitable servo stabilizer with wide input voltage range with
high & low cutoff may help in protecting the equipments.
