3.6.3 3-Phase 3-Wire Power Networks

3.6.3.1 3-Phase 3-Wire ∆ (with 2 current sensors)
∆
For 3-Phase 3-Wire measurements using two current sensors:
■
Connect the terminal V1 test lead to the L1 phase
conductor
■
Connect the terminal V2 test lead to the L2 phase
conductor
■
Connect the terminal V3 test lead to the L3 phase
conductor
■
Connect the terminal I1 current probe to the LI phase
conductor
■
Connect the terminal I3 current probe to the L3 phase
conductor
Ensure that the current arrow on the sensor is directed towards
the load. This ensures proper phase angle for power measure-
ments and other phase sensitive measurements.
3.6.3.2 3-Phase 3-Wire ∆ (with 3 current sensors)
∆
For 3-Phase 3-Wire measurements using three current sensors:
■
Connect the terminal V1 test lead to the L1 phase conductor
■
Connect the terminal V2 test lead to the L2 phase conductor
■
Connect the terminal V3 test lead to the L3 phase conductor
■
Connect the terminal I1 current probe to the LI phase
conductor.
■
Connect the terminal I2 current probe to the L2 phase
conductor
■
Connect the terminal I3 current probe to the L3 phase
conductor
Ensure that the current arrow on the sensor is directed towards the
load. This ensures proper phase angle for power measurements
and other phase sensitive measurements.
