What is a phase sequence meter?
Phase Sequence Meter Phase sequence meter is used for detecting the sequence of the supply in three-phase electric circuits. Since the direction of rotation of three phase electric motors can be changed by changing the phase sequence of supply.
What is a phase rotation meter?
A phase rotation meter, as shown in figure 1, is a device used to determine the phase order of a three-phase electrical system. In electrical system that contains three phases, A, B, and C, it is important to know the order before a motor or generator is mechanically connected to the electrical system.

How to determine the phase order of an electrical system?
Due to limited access to the wiring from the electrical system is important to use the phase rotation meter to determine the phase order. In this type of meter, a couple of arrangements of lamps with capacitor or inductor are employed in order to point out the phase sequence.
