As the old saying goes, “you can have it done fast, or you can have it done right.” But it’s worth noting that this is indeed an old saying, and today it is possible to have something done right as well as done fast. Take, for example, electrical prefabrication for industrial construction projects. By prefabricating elements such as e-houses, data centers and others, builders can streamline project timelines as they also enhance jobsite safety and the quality of the resulting

Electrical testing is an important part of delivering prefabricated electrical systems that are ready for efficient installation. When assemblies are fabricated in a controlled environment, testing and quality-control activities can be incorporated into the off-site production process before equipment reaches the jobsite. Understanding what is NETA certification can help contractors, project managers, engineers, and facility teams understand the qualifications behind certa

Transformer monitoring gives industrial facilities greater visibility into the condition and performance of critical electrical equipment. By tracking temperature, electrical conditions, oil health, vibration, and other operating parameters, teams can identify changes that may require further investigation or maintenance. For organizations considering how to monitor a transformer, the monitoring technology is only part of the equation. The way sensors, controls, communicat

Every second of downtime in an industrial facility means a substantial amount of productivity and money lost. This is why it’s important for facilities to have redundant power systems set up in the event of a power emergency. One of the most common ways to build that crucial redundancy is paralleling generators. Having a system of parallel generators means facilities can have the backup power they need when their regular electrical source is cut off, but these systems require

Electrical systems need to be safe and ready to perform from the moment they’re energized. Electrical testing helps verify that systems meet those expectations, identifying potential issues and confirming compliance requirements while ensuring equipment operates as designed. Testing plays an important role throughout the entire lifecycle of an electrical system, from manufacturing and installation to maintenance and troubleshooting. While field testing remains a must, mor

Industrial facilities come with a huge amount of electrical infrastructure that is needed to keep all equipment and systems running as smoothly and effectively as possible. From the largest distribution panels to the smallest cable assemblies, every element of a facility’s electrical systems must work as expected to verify the systems’ performance, reliability, safety, and compliance of its operations. This makes the process of electrical commissioning essential for the succe

Switchgear is a critical element of any facility’s electrical infrastructure. Consisting of fuses, switches, conductors, and more, switchgear is essential for regulating and isolating current. Because of the impact it can have on the performance and safety of an industrial facility, it’s extremely important to make sure switchgear functions as it should. Testing and verification must be performed on a regular basis to make sure switchgear is in good condition and offers t

An electrical cable tray is a structural support system designed to carry, organize, and route electrical cables. Cable tray systems are widely used to distribute power, control, instrumentation, and communication cables throughout industrial facilities. Cable trays differ from raceways such as conduit. A raceway is generally an enclosed system that provides a protected pathway for conductors, while cable trays are typically open or ventilated support structures. Their ope

Electrical testing is a critical part of delivering reliable prefabricated systems. For DuFab Manufacturing, where electrical assemblies are built and tested off-site in a controlled factory environment, testing provides an opportunity to identify problems before equipment reaches the jobsite. Primary vs secondary injection testing represents two important approaches for verifying the performance of circuit breakers, protective devices, and associated trip systems. Choosin
