3-Phase 4-Wire; 3-Phase 4-Wire Open - AEMC PEL102 User Manual

3.6.5 3-Phase 4-Wire ∆
High Leg configuration. No Potential Transformer (Voltage Transformer) is connected; the installation under test is sup-
posed to be a low voltage distribution system.
3.6.5.1 3-Phase 4-Wire ∆
For 3-Phase 4-Wire
sensors:
■
Connect the terminal N test lead to the neutral conductor
■
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.
3.6.5.2 3-Phase 4-Wire open ∆
For 3-Phase 4-Wire Open
rent sensors:
■
Connect the terminal N test lead to the neutral conductor
■
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 measure-
ments and other phase sensitive measurements.
