3-Phase Sequence & Motor Rotation Indicator – AC Voltage and Frequency Tester
Portable 3-phase sequence detector for identifying phase order, phase loss, and motor rotation direction in three-phase electrical systems and motors.
This 3-phase sequence and motor rotation indicator is a compact, handheld instrument designed for electricians, technicians, and maintenance professionals working with three-phase power systems and electric motors.
The tester allows fast identification of phase sequence (L1-L2-L3) and phase loss, helping prevent wiring errors, equipment damage, and incorrect motor rotation. Advanced models also support non-contact motor rotation detection, allowing users to determine the direction of a motor’s rotating magnetic field without connecting test leads—simply position the device above the motor during operation.
With automatic ranging, a clear digital display, and wide AC voltage and frequency coverage, this instrument is ideal for motor installation, commissioning, troubleshooting, and routine maintenance in industrial, commercial, and infrastructure environments.
