WORKING PRINCIPAL
TechBrij: HTML Table
When correctly connected to three phases R, Y & B. The clockwise rotation of white disc with BLACK ARROW shows that the phase sequence is correct. |
If the rotation is anti-clockwise one of the phases is reversed. |
This works from 50 to 500 volts AC |
This must be used in horizontal position |
Warning : This should not be left on the circuit and be removed immediately after testing the phases. |
