A four quadrant metering system is the metering of bi-
directional energy flow. The system must be able to meter
leading and lagging reactive energy (varh) for import
active energy (Wh) and leading and lagging reactive energy
(varh) for export active energy (Wh).

Answer / sath

This meter is used to measure the value in bi-directional
transmission lines.As the meter is 4 quadrant capable, it
gives forward, reverse and net readings.The meter should
deliver same accuracy of measurement irrespective to the
metered quadrant.

Answer / javed

It is Metering system which is used to measure Real &
Reactive Power and Energy. It is capable of measuring in
all Quadrants of Power i.e. for all possible combinations
of real & reactive Power Metering +P, -P, +Q and -Q in P-Q
(Real-Reactive) axis system

Answer / manish sharma

Four quadrant is a bidirectional metering system which is
capable of measuring power as below:
1. Active import while reactive import (PF lag)
2. Active import while reactive export (PF lead)
3. Active Export while reactive import (PF Lag)
4. Active export while reactive export (PF lead)

Answer / d.h.waiker

Four quadrant meters are those meters which can measure and
records the following parameters.

1) KW/KWH
2) KVA /KVAH

3) KVR/KVARH ( LAG )

4 ) KVR /KAVRH (LEAD )
