Expert commissioning support for DC electrical systems
Getting a DC electrical system installed correctly is only half the story. G Corner's commissioning service ensures every system we supply is verified, validated, and performing to specification before it enters sustained industrial operation, giving you the confidence to run from day one.

Introduction
Over 40 years of commissioning DC electrical systems across the world. Commissioning is the critical bridge between installation and operation.
It is the point at which engineering intent is tested against reality, and where any deviation from specification must be identified and resolved before it becomes a costly operational problem.
G Corner has been commissioning high-current DC electrical systems for over 40 years, supporting clients across the global metals refining and chemical processing industries. Our commissioning philosophy is built on technical discipline, methodical planning, and close collaboration with customers and their appointed contractors. The result is a consistent, structured process that delivers safe, reliable, and performance-optimised systems regardless of project location or scale.
Cold commissioning is the critical pre-energisation phase. Before the system is powered, G Corner's engineers conduct a rigorous series of mechanical and compliance checks to confirm the installation is sound and ready for safe energisation. This includes assembly sequence verification, torque value validation on every bolted connection, correct marking and identification of all components, insulation level checks, and dimensional verification against civil datum. Nothing is energised until every item on the checklist is signed off.
With cold commissioning complete, G Corner proceeds to hot commissioning, energising the system and validating its electrical and thermal performance under live operating conditions. Using calibrated instruments and thermal imaging equipment, our engineers measure voltage drop across busbars, trunk lines, joints, and intercell connections, monitor temperature rise at critical connection points, and evaluate overall system behaviour under load. This phase confirms that the installation performs exactly as designed in real operating conditions.
Every commissioning assignment concludes with a detailed commissioning report. This document provides full traceability of the commissioning process and serves as a valuable reference for the customer's future maintenance programme. Reports typically include detailed test results, voltage drop measurements, temperature rise data, torque charts, dimensional alignment records, and visual documentation including photographs and site observations.
G Corner works closely with the customer's team and their appointed contractors throughout the commissioning process. Our engineers coordinate directly with site teams, support clear communication at every stage, assist with the resolution of technical issues, and ensure smooth integration with installation schedules. Commissioning is never a handover event: it is a shared process carried out in partnership with the client.
Experience & Expertise
A four-decade track record of commissioning high-current DC systems in the world's most demanding process environments
G Corner's commissioning capability has been shaped by more than 40 years of field experience across some of the world's most technically demanding electrochemical installations. That depth of exposure means our engineers understand the behaviour of large-scale conductor systems, the critical factors that influence performance and safety, and the practical challenges that arise on site.
Every commissioning assignment benefits from this accumulated knowledge. Our engineers foresee potential issues before they arise, apply best-practice procedures developed over decades, and bring a level of technical discipline that gives customers genuine confidence in the systems they are handing over to their operations teams.
Our commissioning teams work to documented standards and structured frameworks, ensuring consistency and accuracy across every project. Whether the installation is in Europe, the Americas, Africa, or Asia Pacific, the same rigour applies.
