Does increase or decrease of reactive load affects the Voltage...

Answer / moody

of course
when load pf is constant and the load current increase the
t.v decrease " lagging p.f"
at leading pf the t.v increasing
this occurs in synch generators
if the load is constant but the p.f changed or varried
the same operation happens in lagging , leading respectivly

Does increase or decrease of reactive load affects the Voltage...

Answer / rahul

Yes it does.
Reactive loads ABSORB VARs. This may lead to deficit VARs
in the system causing VOLTAGE to GO DOWN.
( Note that EXCESS VAR___High VOltage
DEFICIT VAR___FAll in voltage)

Does increase or decrease of reactive load affects the Voltage...

Answer / ritesh

yes, when reactive load is changed, the load power factor is
also changed. line current= active power/(voltage*pf),
therefore line current will also change for a constant load,
which will change the line voltage drop, therefore terminal
voltage will also get change.
