Commissioning & Acceptance Testing
Commissioning and acceptance testing is how you find out before the switch is thrown, not after. Transworld Electric verifies that your new electrical systems are safe, correctly configured, and ready to perform to specification, protecting your warranty, your schedule, and your people from day one.
New electrical equipment doesn’t come with a guarantee that it was built, shipped, and wired correctly.
Our commissioning and acceptance testing services include:
- Acceptance testing of switchgear, transformers, breakers, cables, and protective devices.
- Verification of equipment settings against coordination studies and design documents.
- Insulation resistance, contact resistance, and ratio testing before first energization.
- Functional testing of protective relays, controls, and interlocks.
- Point-to-point wiring verification and torque checks on connections
- Startup support and initial energization oversight.
From troubleshooting and replacing parts to updating software, we ensure your VFDs are calibrated for top performance.
What is commissioning and acceptance testing?
Commissioning and acceptance testing is the process of verifying that newly installed or recently upgraded electrical equipment is functioning correctly and safely before it is energized for the first time. Testing confirms that all components have been installed in accordance with design specifications, that protective devices operate as intended, and that the system is safe and ready for service.
Why is commissioning testing important?
Commissioning testing identifies installation defects, wiring errors, equipment faults, and configuration issues before a system is put into service. Catching these problems early prevents equipment damage, safety incidents, and costly repairs that would otherwise occur after energization.
It also provides documented evidence that the system was installed and tested to the required standards, supporting warranty claims, insurance requirements, and regulatory compliance.
What types of electrical systems does Transworld Electric commission?
Transworld Electric provides commissioning and acceptance testing for a broad range of electrical systems and equipment including switchgear, transformers, circuit breakers, protective relays, motor control centers, cables, and power distribution systems across low, medium, and high voltage applications. Both new installations and upgraded or retrofitted systems can be commissioned by Transworld Electric.
What does Transworld Electric's commissioning testing process involve?
Transworld Electric works closely with each client to develop a tailored commissioning testing plan based on the specific equipment and system being commissioned.
Testing typically includes visual inspections, insulation resistance testing, contact resistance testing, functional testing of protective devices, relay testing, and verification of control and protection schemes. All results are documented in a detailed commissioning report.
Does Transworld Elelctric provide commissioning documentation?
Yes. Transworld Electric provides comprehensive commissioning documentation including test results, equipment data, and sign-off records. This documentation is essential for regulatory compliance, insurance purposes, and future maintenance reference. It also supports the handover process between contractors and facility operators.
