Overview
Synchronoscopes are circular scalemeters with step motor, for Varying and Steady Load 3-Phase Current.
The scale has an indicator mark, as well as a red arrow identified with “+” and a black arrow identified with “-“. The pointer is capable of rotaring in both directions. It only points to the indicator mark if frequency and phase sequence are identical for both electrical circuits. If the pointer comes to rest on any other point, the frequencies may be identical but the voltages are not in phase. The direction of movement of the pointer varies depending upon how the circuit and the generator are connected to the synchronoscope (pointer can be made to move clockwise or counterclockwise for higher generator frequency).
Models
SY96 (96x96mm)
SY144 (144x144mm)
SY96 and SY144 are analogue panel meters with Electrodynamic Ratio Elements and Rotating Pointer.
