high voltage generator testing upgrade ... genset...the generator under test to a newly installed...

Project Value: £1,600,000

Project Overview:ACS managed the development and installation of upgrades to an existing high voltage substation to increase the current testing capabilities in Test Cell 7 at the Cummins Generator Technologies’ Ryhall Road facility in Stamford, UK. This project expanded Cummins’ ability to test the complete range of generators from 380VAC at 7,597Amps to 13,800VAC at 240Amps. New electrical equipment including a transformer, reactors and high/low voltage circuit breakers were also installed to electrically couple the generator under test to a newly installed slave generator. A new control room and office structure was also constructed next to the existing test cell.

Key Performance Features:SubstationA concrete block substation was constructed to house existing equipment and new switchgears. Trenches were also installed from the new substation to the test cell and exterior transformer/reactor for the high voltage cables.

TransformerA bespoke 11kv/380-720v transformer was supplied

to meet the expanded testing criteria.

ACS Services: ACS held a single-source contract for design and construction management; equipment specification, procurement and installation; integration of equipment and facility systems; and commissioning.

Project Duration: 10 months

Completion Date: September 2012

Control Room and OfficeA two-story control room/office/viewing suite was constructed next to the existing test cell to offer more room for added testing technicians, an expanded control console and a viewing suite of the test cell for Cummins’ customers.

Reactor & High Voltage SwitchgearA bespoke reactor and high voltage switchgear was supplied to meet the expanded testing criteria.

Controls and Data Acquisition SystemElectrical containment was installed from the control console to the newly installed equipment for PLC control and data measurement. A detailed cause and effect matrix was generated to startup and shutdown all the equipment.

Cell VentilationThe existing cell ventilation system was upgraded to automate the fans with VFD’s and a new control sequence.
