Electrical Measurements & Installation Inspections
Electrical measurements and inspections are a crucial part of ensuring safe electrical installations. Our services are suitable for both public spaces — such as offices, warehouses, hotels, and retail stores — and private properties, including residential homes, farm buildings, and other structures.
According to the Cabinet of Ministers Regulation No. 238 “Fire Safety Regulations” [Ministru kabineta noteikumiem Nr.238 “Ugunsdrošības noteikumi”] (19.04.2016), electrical installations — including grounding and lightning protection systems — must be inspected regularly:
At least once every 10 years;
Every 2 years in explosive environments;
Annually in chemically aggressive environments.
To help clients comply with these requirements and ensure safe operation, we offer a complete range of measurement and inspection services:
Insulation resistance testing of electrical installations;
Loop resistance testing (“phase–neutral”);
Grounding system resistance and continuity checks;
Lightning protection system inspections;
Quality checks of connection points using certified thermographic equipment;
Preparation of inspection reports signed by a certified specialist.
Outcome:
Our measurements and inspections are designed to ensure that your electrical installation is safe, efficient, and fully compliant with regulatory requirements.
