Mobile like an analyser, connected like a meter, intelligent like a platform. VISU brings all three together.
Comparing three ways to measure a site with no sub-metering.
| Field criteria | Fixed sub-metering | Portable analyser | VISU Box |
|---|---|---|---|
| Installed with no shutdown or works | works, lock-out | ||
| Several feeders at once | one point at a time | 9 three-phase feeders at once | |
| Movable from site to site | permanently installed | ||
| Remote, real-time monitoring | depends on BMS | read on site | |
| Automatic reports and recommendations | raw export | ||
| Connected to your tools, or standalone | |||
| Controlled cost per campaignhardware + time spent | purchase and install on each site | manual readings | case reused |
Two questions separate the solutions on the market: is the data measured or estimated? Can it be moved without works?
Dot size: number of feeders measured at once. Indicative positioning.

Former temporary power expert in industry and major events. He came up with the VISU Box to measure what nobody could see. He now leads the company's development.

Expert in IoT, instrumentation, metering, data collection and transmission. He designs the hardware and software, right through to the VISU Live platform.

Installation, commissioning and on-site mission follow-up.
Grid operators observe voltages and trips at national scale. At the point of delivery, where electricity is consumed, data is often missing. VISU provides it.
| Phenomenon | Seen by the grid | Measured by VISU | What the link brings |
|---|---|---|---|
| Overvoltage | Voltage constraints on transmission | Voltage per phase at the main switchboard, time-stamped peaks | See how an upstream constraint propagates to the end use |
| Trips | Detection where instrumentation exists | Temporary instrumentation where none exists | Fill the data gaps |
| Post-incident | Timeline, simulation | Multi-point signature, technical note on D0 | Tell an upstream event from a local fault |
