Phase & Motor Rotation Meter

Model 302

The model 302 is a 3 phase presence and rotation meter combined with a 3
phase motor rotation tester. It is the quickest and easiest way for servicing,
repairing and electrical maintenance of 3 phase systems and 3 phase rotating
machinery. It can be utilized on a 3 phase powered system (the supply side)
or on a three phase un-powered motor (the load side) without having to
worry about damage to the tester. When utilized on a 3 phase powered
system, the instrument is then utilized as a 3 phase presence and rotation
indicator. When utilized on a three phase un-powered motor, the instrument
is then utilized as a 3 phase motor rotation tester. When utilized on a 3
phase powered system, this instrument is a rotary field indication instrument
which display all three phase by lighting up it's corresponding LED. It
displays the rotation (clockwise or counter-clockwise) on a LED. When
utilized on a 3 phase un-powered motor, it is also possible to determine the
motor connections U, V, W without a live circuit to avoid subsequent
damages of e.g. pumps to reversed motor rotation. It displays the rotation
(clockwise or counter-clockwise) on a LED.

Applications

With this equipment, you can, before connecting supply to load :
On the supply side ;

• Quickly verify the presence of the three phase on a
3 phase power system.

• Confirm the phase rotation on a powered 3 phase system.

On the motor side (Load) ;

• Confirm the phase rotation on a unpowered 3 phase motor 3

phase alternator.

• Confirm that each winding is connected to the terminals

of the motor, when the rotation LEDs light up.
