Construction & Infrastructure

Modern buildings and infrastructure cover building electromechanical power distribution, lightning‑protection grounding systems, municipal outdoor facilities, machine‑rooms, warehouses and clean‑building scenarios. It covers the full life‑cycle of construction acceptance, delivery verification and predictive maintenance. Tests and monitoring including electrical hipot & insulation, grounding safety, power quality, over‑heating risk, partial discharge and multi‑parameter indoor environment are carried out to identify hazards such as electric leakage, grounding failure, excessive temperature rise and out‑of‑spec environmental parameters, ensuring safe and stable operation of building electromechanical and municipal public‑utility facilities.

Itemized Test Solutions

1. Building Power‑Distribution Electrical‑Safety Test

Test Purpose: Complete insulation, grounding and leakage‑current inspection for cables, switchgears and backup power supplies, evaluate construction quality and identify fire risks caused by electric leakage. Test Content: Cable insulation resistance test, protective‑grounding grid test, residual leakage‑current measurement of distribution loops, health assessment of building UPS storage batteries.

2. Power‑Quality & Electrical‑Equipment Hidden‑Trouble Diagnosis

Test Purpose: Condition inspection for transformers, busbars, switchgears and reactive‑power compensation devices; detect early defects including excessive harmonics, three‑phase unbalance, joint over‑heating and partial discharge. Test Content: Harmonic & three‑phase unbalance analysis; infrared temperature screening for busbars & terminals; acoustic partial‑discharge localization for switchgear & cable joints.

3. Hipot Safety‑Compliance Test & Construction‑Site Electrical Commissioning

Test Purpose: Safety‑compliance verification for incoming electrical components and on‑site equipment commissioning; verify isolation hipot performance and ensure operator safety. Test Content: AC / DC hipot and IR insulation safety‑compliance test for electrical components; on‑site voltage & current measurement; live‑circuit verification.

Faced with high-intensity construction rhythms and harsh outdoor environments, our high-precision rangefinders, thermal imagers, and professional electrical testing equipment can quickly penetrate blind spots in concealed projects and accurately identify hidden dangers in mechanical and electrical systems. We will continue to use high standard and high reliability testing tools to fully meet the diverse testing needs of the construction and infrastructure fields, and provide strong support for engineering construction.
