Utilities & Municipal Case Studies
 

Case Study 1 - Water  


A local authority wanted an on-line monitoring system for failure alarms on sewerage pump stations.The pump stations were fitted with local alarms, however if these were ignored, sewerage overflow resulted in environmental complaints. The authority used Crouse-Hinds Industrial Wireless I/O units as a cost effective solution.  Pump run and fault status,  and wet-well overflow status is transmitted back to a central computer. Because of the intelligent network functionality in the Crouse-Hinds Wireless units,  each pump station only has to transmit as far as the nearest pump station, negating the need for expensive mast and antenna installations.

Case Study 2 - Electricity


A power authority fitted through-fault alarm sensors to HV overhead lines, and required fast notification of alarms. The sensors were mounted on remote HV poles and were not easy to connect to the existing RTU network monitoring the network. The authority connected the sensors to Crouse-Hinds wireless I/O units,  which transmit immediately on alarm. The wireless units are battery powered as although HV power is available in abundance,  LV power could only be obtained by installing transformers.

Clusters of wireless units transmit to the closest RTU which feed the alarm information into the network SCADA system. Under normal non-alarm conditions, the wireless units transmit a daily “health” signal with battery supply voltage.

Case Study 3 - Gas


A gas reticulation company used Crouse-Hinds Wireless units for real-time flow metering. The real time study provides long term system management information for infrastructure planning.
