Handheld Phase Identification Tool for Power Distribution Networks

Phase Identification Tool for Electricians

Easily identify phases with the DEWESoft GridPhase handheld tool.
It uses smart technology to quickly measure and track phases with minimal setup, making it perfect for utilities, DNSPs, and power technicians.

The Gridphase handheld unit measures voltage, frequency, and phase angle using GPS-synchronised sampling. This ensures accurate, real-time phase identification—even across transformer groups and over large distances. Simply connect the device at the test point, pair it via Bluetooth with your smartphone, and the system compares the live signal to the reference phase.

✅ Simple and fast phase identification
✅ Measures voltage, frequency, and phase angle
✅ Accurate across low and high voltage networks
✅ Ideal for utilities, DNSPs, electricians, and contractors

Accurately Identify Phases Anywhere.

The GridPhase Handheld Phase Identification Tool is a simple, reliable, and accurate solution for field phase identification — perfect for the electrician’s tool kit. Designed to help utilities, contractors, and field technicians quickly identify the phase of any connection in a low-voltage distribution network, GridPhase saves time and prevents costly errors.

✅ How It Works

The GridPhase Handheld Phase Identification Tool provides fast, reliable, and accurate phase identification of live conductors anywhere in your electrical installation.

  1. Start at the distribution cabinet — begin phase identification where you need to verify or map phases.

  2. Power on the GridPhase device and connect it to your smartphone via Bluetooth.

  3. Synchronise the device with the GPS clock to ensure precise, time-aligned measurements.

  4. Establish a reference point for comparison — this is your baseline phase (e.g., assign Phase 1 to this point). All other measurements will be referenced against this phase.

  5. Take measurements directly on fuses or circuit breakers throughout the installation.

The instrument instantly and accurately identifies the phase of each connection. With GridPhase, you can easily track phases, verify installations, and redistribute loads — ensuring safer, more stable, and balanced operation of your electrical systems.
