Hioki PD3129-10 Non-Contact Phase Sequence Detector Hioki

Hioki’s non-contact voltage detection and measurement technology places efficiency and safety as priority considerations with the goal of protecting customers that need to conduct on-site electrical work as part of renovations and expansions of manufacturing plants and buildings. Model PD3129-10 is a non-contact phase rotation meter that detects the phase of electrical current flow within insulated wires without using metallic contact voltage clips. The green arrow indicates the normal phase, which can be useful for visual reports that document the proper completion of electrical work. The HIOKI Phase Detector PD3129-10 helps alleviate the extra costs and cuts labor hours by providing a safe way to detect phase sequences on distribution panels and motors by incorporating fully enclosed ABS-molded clips with absolutely no metal exposure. In the instrument, an electronic induction voltage sensor is employed to enable accurate phase detection of insulated conductors. This innovative technology has enabled HIOKI to provide CATIV600V/CATIII 1000V safety characteristics often required by large power utilities and similar potentially hazardous working environments.

The Hioki PD3129-10 is designed to safely detect the phase sequence in three-phase circuits for electrical installation and maintenance. Conventional metallic-contact phase detectors are constructed with a voltage cable with standard metallic clips, requiring the technician to clamp onto exposed metallic parts of the conductor and introducing the potential danger of electric shock accidents and short-circuit accidents caused by accidental contact between two metal points. Needless to say, ensuring safety in electrical work has been an increasingly important issue. A long-standing proponent of safety at the workplace, HIOKI released the 3129 Non-Metallic Contact Phase Detector in 2004 and achieved the goal of ensuring a safe working environment for our users. To enable more electricians to take advantage of our advanced technology, we have increased the range of vinyl-insulated wires that can be clipped with the non-metallic voltage clips to up to 500 mm2 in size, and extended the operating voltage range to 1000V AC. With the all-new Phase Detector PD3129-10, safe phase sequence testing can now be conducted in even more environments where the previous non-metallic-contact phase detectors could never be safely applied.
