Partnership Delivers Three-Phase Power To Rural Areas

Single Phase Power Solutions (SPPS) provides partnered with NEW YORK Electric Cooperatives to supply proven, reliable, three-phase power answers to rural areas where it isn’t accessible, and/or cost prohibitive to create in. SPPS manufactures the 1-to-3 Power Source™, which includes a BELLE™ Motor using Written-Pole® technology to provide three-phase power from single-phase utility service. This process eliminates the high maintenance and fuel prices, and the pollution of fossil-fuel-powered Gen-Sets, while providing power quality compared to that of the standard phase converter. It really is far more affordable than extending three-phase power where it isn’t available.

Obtainable in 50 HP, 75 HP, and 100 HP configurations, the 1-to-3 Power Source would work for a broad selection of industries and applications services by the NC Electric Cooperatives, which includes mining, agriculture, and commercial and industrial sites.

“Building on the successes that we’ve got with recent EV charging stations in NC through our EdgeEnergy™ division, we’re very happy to formalize this partnership with the NEW YORK Electric Cooperatives,” mentioned SPPS Sales and Marketing Manager Ben Morris. “A lot of North Carolina is usually rural, and without usage of three-phase utility service. Our technology delivers clean, stable, three-phase power from single phase utility service, allowing companies to power the three-phase motors that they have to manufacture good and services.”


A Written-Pole single-phase motor can drive a three-phase conventional generator to create clean, well balanced voltage. The converter circuit can begin multiple smaller three-phase motors. The 1-to-3 Power Source can begin a single motor around about 50% of its rating, along with other smaller motors around its output rating, supplying flexibility and cost benefits thus.

Due to the high load synchronizing capacity for the Written-Pole® drive motor, a big flywheel can be put into improve the motor beginning capacity of the three-phase generator.


Extending three-phase distribution will be expensive, typically between $30K to $110K per mile. Utilizing a 1-to-3 Strength Source avoids that price. Utilities amortize the high cost to increase distribution often, charging customers monthly charges whether they utilize the charged power or even not. Usage of a 1-to-3 Power Supply avoids these charges, that may range between $12K to $60K each year. The written-Pole Motor driving the 1-to-3 achieves a complete load efficiency exceeding 88%, every year that may reduce energy costs by thousands. Because the 1-to-3 input runs at unity power factor, there is absolutely no power factor penalty, a substantial cost avoidance potentially.

The 1-to-3 can replace the diesel or gas engines which are often used because the prime movers for pumps and generator sets. Along with adding fuel, these engines need significant upkeep and maintenance such as for example filters, spark plugs, belts, oil changes, and much more. The Written-Pole motor requires hardly any maintenance compared. Air and noise pollution are reduced, but most of all reliability is improved with the 1-to-3.

The 1-to-3 enables weak single-phase lines to provide strong three-phase power with excellent voltage regulation and precise 60 Hz frequency. The generator output voltage provides well-well balanced three-phase power with the capacity of starting and running large three-phase motors and power quality-sensitive electronic controls. This equipment isolates the application form (and the utility) from harmonics which are bad for sensitive loads.

Written-Pole motors begin using only one 1.7x their rated working present. This eliminates the surplus voltage sag or “flicker” that may cause problems on distribution lines. The efficiency rating of the electric motor is 95.5% and the generator efficiency is 93.5%, leading to a standard efficiency of 89% with 10% electrical isolation. With the 1-to-3 Power Source customers served by single phase lines will get high-quality power for three-phase applications. Unlike conventional phase converters, the 1-to-3 provides true, balanced, three-phase power; eliminates disruptive harmonic feedback; is really a unity power factor load to the utility; sufficient reason for an extra flywheel, can ride through momentary power interruptions easily.
