Phase rotation direction test


Press
signalling that the device is ready for operation.

Connect measurement probes to the TKF-13 tester.

Connect measurement probes to the points where there is the ex-
pected three-phase voltage (see the illustration below).

If the phases at the given measurement points are compliant with
the L1, L2, L3 description, the R diode of the tester will go on;
otherwise the L diode will go on.

The light of the given neon lamp (L1, L2, L3) signalises a voltage
exceeding 100 V between the corresponding probe and one of the
remaining probes.

Motor shaft rotation direction (using leads)


Disconnect the motor from the mains.

Press
signalling that the device is ready for operation.

Connect measurement probes to the TKF-13 tester.

Connect measurement probes to the tested motor (see the adja-
cent illustration).

Rotate the motor shaft energetically in the desired direction.

The light of the R diode means the connection to the U, V and W
motor terminals of phases L1, L2 and L3, respectively, will cause
rotation of the motor in the direction the shaft spun during the test.

The light of the L diode means the connection to the U, V and W
motor terminals of phases L1, L2 and L3, respectively, will cause
rotation of the motor in the opposite direction to the direction the
shaft spun during the test.

Make sure the shaft rotates in the desired direction once the mo-
tor has been connected to the power supply source performing a
phase sequence test (see Chapter 2).
to turn the tester on. The green diode should go ON
Incorrect indications of the tester may be caused by one of
the following:

connection of two probes to one phase,

connection of one of the probes to the neutral lead,

lack of connection of one of the probes to the mains.
to turn the tester on. The green diode should go ON
