Phase Identification Tool for Power Distribution Networks

Easily identify phases across your entire network with the DEWESoft GridPhase system.

The reference device and handheld tool work together using GPS-synchronised technology to deliver fast, accurate phase identification — even through transformers. With minimal setup, it’s perfect for utilities and power distribution technicians.

✅ GPS-synchronised phase comparison
✅ Reliable over large distances and transformer groups
✅ Ideal for utilities, DNSPs, and field crews

Gridphase Phase Identification System – Reference & Handheld Unit

The GridPhase Phase Identification System from DEWESoft is a cutting-edge, GPS-synchronised solution designed for utilities, DNSPs, and power distribution technicians needing fast and accurate phase identification across complex high, medium and low-voltage networks.

The system consists of:

  • A GridPhase Reference Device installed at a central point (e.g. substation or HV busbar)
  • A compact GridPhase Handheld Unit for use in the field

Together, they deliver network-wide phase identification, even across  sub-stations, transformers and large distances — making the GridPhase system essential for maintaining network balance, reducing neutral current, and ensuring correct phase connection during installations and maintenance.

✅ Key Features

  • GPS-Synchronised Phase Measurement
    • Ensures accurate time-aligned voltage angle comparison between the reference and the handheld unit
  • Large Coverage Area
    • One reference can support handheld units across hundreds of kilometres
  • Patented Transformer Phase Shift Compensation
    • Automatically adjusts for phase angle shifts caused by transformers, eliminating the need for manual correction
  • Compact and Field-Ready Handheld Unit
    • Bluetooth-enabled, with measurements displayed on a mobile app
  • Contactless Measurement Capability
    • Integrated capacitive sensor for safe operation on live conductors
  • Mobile App Interface
    • Shows live phase angles and calculated phase labels (A/B/C)

🌐 GridPhase Web – Centralised Phase Tracking Across the Grid

The GridPhase Web software allows utilities to:

  • Integrate a simplified network model to automate voltage angle shift compensation from transformers
  • Save and pair measurements at different times and locations
  • Maintain a consistent phase reference frame across the entire network
  • Enable remote validation and tracking of phase data across field teams

This powerful cloud-based interface ensures ongoing accuracy and data consistency in wide-area distribution systems, enhancing network reliability and decision-making.

🛠 How It Works

  1. Install the GridPhase Reference Device at a known high-voltage point.
  2. Connect the handheld unit in the field and sync via GPS.
  3. Assign a phase (e.g., Phase A) at the reference location.
  4. Measure voltages at field locations — the system compares angles and identifies the phase in real time.
  5. Optionally store and sync data via Gridphase Web for full network visibility.

The Gridphase Reference Device measures voltage and phase angle at the central node and transmits this GPS-synchronised reference across the network. This allows all handheld units in the field to compare their local measurements accurately, even across transformer vector groups and large geographical areas.
