Introducing Dewesoft Gridphase: one device for fast and reliable phase identification

Gridphase is a compact vector voltmeter that simplifies phase identification anywhere on the power network—behind or in front of the meter.

Using synchrophasor technology, it delivers accurate results without the need for reference installations or complex setups. Designed for field use, it supports contactless detection on high-voltage lines, automatically compensates for transformer phase shifts, and operates for up to 50 hours on a single charge.
Who it’s for:

Power distribution system operators (DSOs) – for load balancing, transformer checks, and energy meter installations

Electrical installers – for EV chargers, smart homes, reconnections, and troubleshooting

Why Gridphase?

•    Identify phases without disconnecting the supply
•    Safe, contactless detection on HV lines
•    Plug-and-play – no reference site needed
•    Compact, long-lasting, and cost-effective
