For triple phase system
• Measure the tension between line 1 (L1) and neutral (N) and between line 2 (L2) and neutral (N)
and between line 3 (L3) and neutral (N)�
• You should measure 230V in all cases�
For delta triple phase system
• Measure the tension between line 1 (L1) and line 2 (L2), between line (L1) and line 3 (L3)
and between line 2 (L2) and line 3 (L3)�
• You should measure 230V in all cases�
