ATS and Switchgear

USP&E is ready to assist you with your generator's ATS and switchgear needs. We know that after selecting your generator the next most important decision to consider is which ATS and switchgear you need for your power generator setup. USP&E has a large and diverse range of ATS and switchgear options to suitably fit your generator, and we have the expertise to help you use these components for maximum efficiency.

ASCO - Open, delayed transition, and soft load switchgear is available at USP&E. Contact us today, and we will help ensure that your design includes the new or used switchgear you need to have in order to adhere to code and application, all within your budget.

ZENITH - Open or delayed transitions ATS options that are very affordable. We have every voltage and enclosure option imaginable in stock. Click here for pricing info.

CUSTOM - You would like to parallel with the utility and with 3 dissimilar generators and have your soft load switchgear include digital meters that display Hz, voltage, amps, and kW for each generator and the utilities?

We can design, assemble, install, commission, and properly service your custom USP&E manufactured switchgear for a fraction of what the competitors are charging and still provide the most knowledgeable, flexible, and proactive service you have ever experienced.

Power Plant preventative maintenance

Generator Commissioning & Load Bank Testing

For large and small businesses power generators represent a considerable capital investment and support mission critical facilities and processes. Often their malfunction can lead to possible dangerous conditions and significant financial loss.

 Periodic generator maintenance and testing are vital to ensuring that each power station unfailingly performs as expected when called upon to do so.

USP&E's generator engineers know the importance of preventative maintenance practices and periodic operational testing of their genset units. 

Emergency gensets required by a building's safety code require minimum test conditions and frequency of testing are prescribed by applicable codes.

An important preventive measure of a comprehensive generator maintenance program is periodic load bank testing. Rarely is it required specifically by building coding but is often mandated for emergency generator units operating in critical areas like hospitals.

A load bank is a stationary or mobile piece of equipment designed to provide a simulation of the actual electrical load the power generator is supposed to be capable of powering up to.

 Load bank testing shows the generator operator if the equipment is capable of handling the electrical demands that are required of the unit or if it needs an overhaul.

    Power Factor Effect on Generators

    Industrial electrical loads comprise resistance and inductive reactance, with the latter induced by all electro-magnetic devices. Inductive reactance causes current flow to lag the applied voltage by 90 electrical degrees. 

    Solid state electronic devices are nonlinear and their current waveform does not conform to the applied voltage waveform. They, too, cause current to lag the applied voltage in the manner of electromagnetic loads.

    The vector resultant of resistance and reactance is the circuit impedance. Current flow through the resistive component yields kilowatts (kW), and the kW level determines the horsepower load that will be advocated on the genset engine.

     The current flow through total impedance yields kilovolt-amperes (kVA), which converts directly into the heating that will be imposed on the power generator.

    The circuit parameter known as "power factor," or PF, is the ratio of kW to kVA. Power factor is usually conveyed as a percentage integer value. A PF of 080, for example, is typically expressed as 80%. 

    Power factor decreases with increased reactance, and increases as the ratio of resistance to reactance increases. In a purely resistive circuit, kVA is equal to kW, and PF is 1, or 100%.
