Phase Sequence Indicator

It is use for monitoring phase sequence in three phase power network system.

Mechanic phase sequence indicator

Applicable on 100-150V or 150-500V three-phase power network. When the rotation of disc with arrow sign is clockwise,the phase sequence is correct.

Anti-clockwise rotation measns wrong sequence.

Exchanging any two of the three hot wires,obtain the correct phase sequence.Each test should not be longer than 5 minutes.

LED phase sequence indicator

Measuring status of phase seqence: correct phase, incorrect phase of lack of phase.

a. Correct led lit: phase sequence is corrct.

b. Wrong led lit:phase sequence is incorrect.

c.both correct and wrong ledss lit:lack of phase. when the wire is lack of phase and its led will goes off.

With relay output can be customized.
