Improved life cycle costs
27 September 2013
The first UK installation of a new type of medium voltage AC drive has been commissioned at Yorkshire Water’s Blackburn Meadows Wastewater Treatment Works in Sheffield.
Six ACS 2000 drives from ABB have replaced a DC drive system used to control a set of pumps, with motors rated at 2 x 645kW, 2 x 505kW and 2 x 300kW. The multi-pump arrangement is used to transfer wastewater 25m below ground to the head of the treatment works.
Medium voltage drives were selected instead of low voltage drives due to the long cable lengths and overall project costs including the electrical distribution system, variable-speed drives and motors.
