Phase Rotation Test; Specification - Tenma 72-3565 Manual

PHASE ROTATION TEST

• Perform a function test prior to this test.
• This unit can determine the phase rotation
within a three-phase supply.
• Connect the L2 test probe to the supported
phase 2 and the L1 test probe to the
supposed phase 1. If the R LED illuminates
the phases are in the correct sequence 1
to 2.
• Connect the L2 test probe to the supposed
phase 3 and the L1 test probe to the
supposed phase 2.
• If the R LED illuminates, the phases are in
the correct sequence 2 to 3.
• Connect the L2 test probe to the supposed
phase 1 and the L1 test probe to the
supposed phase 3.
• If the R LED illuminates the phases are in
the correct sequence 3 to 1.
• During phase rotation, test touch the
contact electrode. If the LED illuminates
then the phase sequence is anti-clockwise.
