Answer / harshavardhan be, me (unemploy

The power triangle is sum of (kW , kVAR, kVA) and the meter
which gives readings all of the above variables is called
TRI vector meter.
You can see the TRI vector meter installed below the
distribution transformer.
These meters are manufactured by L&T, AREVA, ABB

Answer / virendra joshi

The meter which shows 1. Active power, 2. Reactive Power
3. Apprent power called a Tri vector meter.

Answer / ramesh.a.eee

Trivector meter is Electronic type Energy Meter which
measures energy parameters, like active energy, Reactive
energy,apparent energy, Power Factor, frequency etc.
Through which we can know how much enregy recieved or
sent.Trivector meter has 2 types, one is 3ph 3wire meter n
other is 3 ph 4wire meter.
It is conneceted in the substation to incoming or outgoing
feeders to know how energy is given out or recieved from
other end, or to Transformers on HV n LV side to know the
Transformer loss.

Answer / santhiya

it consist of kvarh and kvah meter along with it and it
measures the total load kva.

Answer / amol salunkhe

the meter which gives amount of total load in kva taken by
any installation.

Answer / kamaraj

TRIVector will be able to give these many parameters,

phase voltage, ph current, power factor, reactance, line
voltage, line current, frequency.

Answer / a.mohammadmujeeb

it is device which is used to measure power
factor ,reactive power(kvar),apparent power(kwh).
and in some types it is used for multiple puporse such as
to measure voltage,current.
