Answer / shyamkr

i totally agree with mr. srivalli but like to add 1 more
point here.short circuit occurs in one phase system when
phase and neutral comes in contact with each other i.e there
is no potential drop occurs phase and neutral wire and phase
and neutral are in same potential,so short circuit.but when
any resistance is used in between phase and neutral,there is
some potential drop occurs between phase and neutral,so
,ther is some potential drop between phase and neutral and
there is no short circuit.

Answer / srivalli

Resistance is device which convert electrical energy to heat energy

so it acts as sink for for electrical source so it does not short circuit the phase & neutral

Answer / sonu kushwaha

Here resistance work as the load . This resistance regard proper voltage drop across the phase and nutral like battery etc.
When this voltage drop equall or greter than the voltage sorce across the phase and nutrel then there is no short ckt
If there is no proper voltage drop across the resistance ( v-ir) then it produce short ckt

dear all, in motor operation , motor is of 100 hp and bimetal relay setting is 130 amp, if relay is getting tripped on 120 amp balance current what can be the reason? Relay is newly replaced. I dont know but is there any frequency effect in thit case? Can frequency variation affect bimetal relay operation?
