Answer / venkat

Trivector meter is used to measure three types of
power.that is active power,reactive power and apparent
power.

Answer / manasa

It is a device that measures the amount of electrical
energy supplied to or produced by residence, business, or
machine.
The most common type is more properly known as a kilowatt
hour meter or a meter. When used in electricity retaining,
the utilities record the values measured by these meters to
generate an invoice for the electricity. They may also
record other variables including the time when the
electricity was used.
It is called as tri-vector meter because it measures energy
consumption of the three phase lines R, Y, B which are 120
phase difference from each other.It measures the
consumption in terms of the active enrgy, reactive energy,
apparent energy, power factor.

Answer / minal

It is used to measure voltage, current & power of a circuit.
As it measures three components so it is called trivector
meter
