Power control system suits for rigours of continuous duty water and wastewater treatment plants

Russelectric, a manufacturer of power control systems and automatic transfer switches, has been awarded the contract to supply Charlotte Water with paralleling switchgear for their water and wastewater treatment facilities.

The paralleling switchgear will monitor the incoming utility power and in the event of a utility power failure, ensure the transfer of critical emergency backup power to their
facility in Charlotte, NC, USA.



Russelectric will engineer and build each of the two generator paralleling control and distribution switchgear systems to control the paralleling operation of three (two present and one future), 4160-volt, three megawatt engine generators.

Uninterrupted transfer of power

Each system will be designed to provide utility paralleling operation of the engine generators with the local utility, to
provide seamless, uninterrupted transfer of power between the on-site engine generators and the incoming utility service.

The control system, a Russelectric engineered solution for Charlotte Water, will utilise redundant PLC controls and include full manual capabilities that would allow for operation of the system in the unlikely event of a failure of the redundant
PLC based controls.

Delivery for the initial system is scheduled for late 2018, with the second scheduled for early 2019.

Russelectric was selected based on its ability to meet the stringent design criteria, delivery schedule and extensive warranty requirement.

“Russelectric manufactures complete systems in-house, with all bus, enclosures, and other structural components fabricated and fully assembled in Russelectric plants here in the US,” said Stephen McQuaid, Russelectric Switchgear Product Line Manager. “As standard, we also perform comprehensive factory testing of the complete systems prior to shipment.”
