Synchronous Motors Retrofits

synchronous motor retrofits company

Synchronous motors that have been well maintained will continue running for many more years. While the motors may be in good working condition, the controls, relays, and DC contactors might need to be replaced. Unfortunately, replacement parts are not always available, especially the field application relay, the most common failure point. Our team of control experts, with more than 15 years experience, can retrofit your synchronous motors with new field control circuits.

Cable Assembly and Testing

Cable Assembly and Testing

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 and preventive 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.

Electrical Infrastructure Design and Automation

Quad Plus provides substation and power distribution system design and automation, including industry electrical requirements, compliance with government regulations, load analysis, system layout and calculations, sizing and specifications for cables, cable trays system, conduit system design and installation, transformers, protective devices, panels, switchgear, capacitor bans, and other required equipment. We will ensure cable layouts do not obstruct site traffic while guaranteeing the most cost-effective layout. Quad Plus has the ability to design, install, and maintain your complete electrical infrastructure and power systems.

Reactive Analysis

If you have an existing problem with the power company, our system integrators will find the source and recommend solutions. We have traveled worldwide to seek out the cause of abnormal voltage fluctuation and current distortion, plus a host of other issues. Drawing on our vast and varied experience, and using the appropriate measuring and modeling tools, we will assist you in resolving your electrical power issues and improve your profitability.

We can perform a power study which will model the control system on the local power grid and show the effect it will have on the electrical system. For most sites, flicker will be the most serious issue, but we can also model other power quality issues such as harmonics and power factor.

Synchronous Motors

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.
