Analysis of Power Quality According to EN50160 – and Beyond
- Year: 2025
- Client: Frewitt SA
- Location: Granges-Paccot
As part of a mandate for an international client experiencing intermittent Wi-Fi disruptions, we conducted a comprehensive audit of the electrical power quality, in compliance with the EN50160 standard.
Our measurement instruments also allow us to analyze electrical events beyond the scope of this standard. We recorded transients at various locations to identify possible disturbances that could be affecting the network infrastructure.

Electromagnetic Field Analysis
- Year: 2025
- Client: Frewitt SA
- Location: Granges-Paccot
In response to concerns about potential electromagnetic disturbances in a client’s premises, we performed a full analysis of electromagnetic radiation in accordance with the Swiss ORNI ordinance (Ordinance on Protection Against Non-Ionising Radiation).
Using high-precision measurement instruments, we detected and characterized various electromagnetic fields present in the work environment. This approach enabled us to identify local sources of interference and propose targeted corrective measures.

Lightning Protection System
- Year: 2025
- Client: Frewitt SA
- Location: Granges-Paccot
Design and Implementation of a Level 1 Lightning Protection System
To secure a complex building composed of multiple sections, we designed and installed a Level 1 lightning protection system in compliance with EN 62305.
The architectural complexity required a custom approach involving lightning rods, down conductors, and a distributed grounding mesh tailored to each section’s structural specificities. This ensures optimal protection against direct lightning strikes and significantly reduces risks to individuals, sensitive equipment, and electrical installations.

Electrical Installation Certification for a School Centre – Minergie-P-ECO Label
- Year: 2025
- Client: School Centre
- Location: Marly
As part of the construction of a school centre designed to meet the highest standards of green building, we certified an electrical installation in full compliance with the Minergie-P-ECO label.
A key requirement of this certification is the reduction of electromagnetic fields – a major concern in environments for children and educational staff. We implemented precise technical measures to ensure that emissions remained well below the required thresholds, thereby guaranteeing a healthy, safe, and sustainable learning environment.

Heavy-Gauge Cable Pulling – Supercharger Installation for Electric Vehicles
- Year: 2025
- Client: [Confidential]
- Location: Vevey
In the context of a fast-charging station (supercharger) installation for electric vehicles, we performed the pulling of large-diameter cables required to power high-capacity charging stations.
This type of project requires strict technical control to meet both electrical specifications and the physical handling of heavy cables. We are equipped with the necessary tools: cable drum trailers, guiding accessories, rollers, and an electric winch for controlled, precise, and secure pulling.
This enables us to carry out efficient installations even over long distances or complex routes, while preserving cable integrity.

Installation on a Mobile Phone Tower – Certified High-Access Work
- Year: 2025
- Client: Swisscom
- Location: Les Ponts-de-Martel
As part of the equipment of a mobile phone mast, we installed technical equipment at the top of the tower to ensure connectivity for antennas and radio devices.
Our team is trained and certified for high-access work, fully compliant with current safety standards. We operate with personal protective equipment (PPE), suitable anchoring systems, and strict procedures to ensure both worker safety and high-quality implementation.
Thanks to our specialized gear, we provide reliable, precise, and secure installations even in complex access conditions. This expertise enables us to meet the needs of telecom operators, network integrators, and any project requiring elevated technical work.
