Answer / venu

If we say it is a balanced system/load it has to obey to
points
1.constant power transfer to the load.(should not vary with
time)
2.no nuetral current.
If it does not obey any of the above we can consider as
unbalanced.

Answer / aruna dixit

A Three phase Loads on a 3 phase supply system is a Balanced
load because it draws equal current from each phase. Three phase
Motors, Converters; Rectifiers using 3 phase input supply are
common examples of Balanced loads.
b. A single phase / 2 phase loads on a three phase system is
called
Unbalanced load. Normally Unbalanced loads have to use a
neutral wire in the system. The 2 phase loads may not require a
neutral.

Answer / saravanan

In Three Phase supply sustem, If any induction revolving
equipments distribution or loading ,should take even
Amperes (Loading), Neutralaizing also should 0 Volts - Its
called Balanced Load . Unbalacing is taking load diffent
Amperes or Neutralizing getting some volts are called
Unbalanced Load.

Answer / mahesh

in three phase if all phasxes have same load and nuetral
current is '0' its ballance load and if is more than then
its unballance load
ir+iy+ib=0

Answer / mahesh

in three phase if all phasxes have same load and nuetral
current is '0' its ballance load and if is more than then
its unballance load
ir+iy+ib=0

Answer / shivam

well thanks for the help,,, but plz can u elaborate it more

Answer / engr shah

in three phase if all phasxes have same load and nuetral
current is '0' its ballance load and if is more than then
its unballance load
ir+iy+ib=0

Answer / rajesh

The phase impedances are equel that is z-phase=z-phase=z-phase that is called balanced system.
The phase impedances are not equal that is z-phase1 and z-phase2 and z-phase3 that is called unbalanced.

Answer / sharique

The phase impedances are not equal that is z-phase1 and z-phase2 and z-phase3 that is called unbalanced
In 3 phase balanced supply, 3 phase have
equal amplitude and frequency with each phase
difference

Answer / rahul bathri

The load circuits Delta with so far were balance Ed circuit s. In balance Ed polyphase circuit the impedance s in different phases are same .now we will consider the methods of solving unbalanced Delta connected and star- connect load circuits I.e the circuits consisting of impedance in one or more phase different from those in other phase .

when the motor was star position that is running ok but when the motor was delta it was tripped? why?

Please give me a solid reason there are 2 ELCB's If we take Phase from ELCB NO:1 an Netural from ELCB N:2 why ELCB is tripping when we connect the Load?please brief me with detail
