Answer / samir

In electrical engineering power is represented as Apperent
power VA,Reactive power VAR and True power KW,and all the
three are represented as a vector because all have value
with derection,trivector meter records all the three power
so it is known as trivector meter.and VA,VAR and KW
represented in vector form so they are three different
vectors.

Answer / rameez

Tri-vector meter is used to measure kVAR, kVA and kVARh...and tri vector is the vector representation of of the 3 quantities....

what is the ATS .And how it works.
