- Description
Description
The Hioki PD3129-10 is a non-contact phase rotation (phase-sequence) meter. It detects the phase order (positive or reverse) of a 3-phase system using insulated wire, without needing metal clips.
It is designed for use in maintenance, installation, and inspection of three-phase power systems.
Key Features
-
Non-metal-contact clips: The clamps clip onto wire insulation, so you don’t need to expose bare conductors.
-
Green LED arrow: Indicates “normal phase” (direction of rotation), which is useful for visual documentation.
-
Rotating LED indicators: Show the three-phase sequence visually.
-
Audible indication:
-
Intermittent beeps for correct (positive) phase
-
Continuous tone for reversed phase
-
-
Magnetic base: Allows the device to stick to a metal panel for hands-free operation.
