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

if power factor comes in leading & showing -0.95. Is there any effect on electrical system? if yes, then please tell me what would be the effects. & how long we keep power factor in leading. Keeping power factor in leading shows more KW & less KVA is it correct or not.

This is about the recent problem that we have faced in our project site. We have 6/7.5 MVA. 66/11kV three phase star - star power transformer. The neutral was solidly connected to the earthing mat. But because of high resistance of earthing mat (130 ohm on LV and 180 ohm on HV), one day LV side neutral earthing conductor melted and we had a huge damage. Can any one plz tell me what might happen when we connect power transformer neutral to the earthing mat which has high resistance (>100 ohm ) ?????
