Acceptance and maintenance testing are critical to ensure your systems are operating safely, effectively, and efficiently while helping to ensure continuous operation and avoid downtime. Acceptance testing is necessary before commissioning to ensure your system is installed according to the engineering design and that the equipment and system are ready for commissioning and energizing. When performed in conjunction with a condition-based maintenance program, maintenance testing will maximize life expectancy while establishing priorities for repair and replacement.

The reliability of your system is crucial for the performance of your operation. Our acceptance testing and maintenance strategies are developed in accordance with NETA-developed consensus standards for testing devices and systems. We understand the need for projects to be completed on time and on budget. We provide quick turnaround for all testing reports along with a cost-benefit analysis of how much of the electrical system should be specified to be tested to ANSI/NETA ATS. Our NETA-certified engineers are available for third-party, independent acceptance testing, and we also provide 24-hour emergency services so you can be confident that your interests are protected.

Electrical cables provide critical links throughout your systems, and cable testing is vital for ensuring that your cables will operate safely and reliably. New cables must demonstrate that they are safe to energize and will hold up during operation. Older cables must be examined to ensure they can continue to perform safely and provide insight into the cable’s remaining useful life.

Quad Plus engineers have the training and experience to not only perform the correct tests, but also to interpret the data collected and provide actionable recommendations. We can locate, isolate, and trace a cable fault on shielded cables using multiple testing types during both acceptance and maintenance testing. Very low frequency testing places less stress on your cables than AC and DC high potential testing while also providing accurate results to check installation quality. Predictive maintenance programs involve partial discharge testing, while Tan Delta testing can identify degrading cables when used regularly. DC high potential testing should generally be avoided for older cables, but is still available when necessary.

You need to get the longest possible working life from your synchronous motors, and the Quad Plus team has the experience to make that happen. A regular maintenance program will allow synchronous motors to continue running for many years, but controls, relays, and DC contactors often need to be replaced. Our extensive network enables us to source parts for obsolete machines. With more than 15 years of experience, our control experts will retrofit synchronous motors with new field control circuits when replacement parts are no longer available.

Along with straightforward repairs, the Quad Plus team is continually working on innovations that go further than simply replacing parts. For example, we can eliminate maintenance items in most applications, including replacing the DC field contactor with an SCR static switch. We design and build each system for motors rather than adapting systems from generators to motors. In particular, we build a power factor regulator into all of our systems to ensure your motors are running at peak efficiency. We have installed more than 65 synchronous motors and are happy to supply references from major companies to demonstrate our work.
