UTILITIES CASE STUDY
See how a UK water management company used Tan Delta oil condition monitoring across its equipment network to extend service intervals and reduce maintenance costs and oil consumption.

THE OPERATION
The case study covers a UK water management company serving an area of more than 12,000 square kilometres. Its equipment portfolio included hundreds of generators and high-volume pumps.
The operator needed to reduce maintenance costs while maintaining reliability across a large, geographically distributed network.
THE CHALLENGE
Rigid time-based servicing led to usable oil being discarded and limited engineering time being spent on unnecessary maintenance.
With equipment spread across a wide service area, the operator needed better information to prioritise servicing while maintaining reliability.
THE SOLUTION
SENSE-3 kits were retrofitted across the equipment network to provide real-time oil condition data. Readings were transmitted via WiFi or 4G, helping the maintenance team assess when servicing was needed.
Sensors continuously track oil condition at the equipment. The SENSE-3 gateway transmits readings for the maintenance team to review remotely.
Oil condition data helps the team plan maintenance around actual equipment need. Abnormal changes can prompt earlier investigation and preventative maintenance.
THE OUTCOME
Using oil condition data to guide servicing, the operator increased the service interval from 400 to 534 hours. Tan Delta reports a 25% reduction in maintenance costs and oil consumption for this application.
Continuous monitoring also supported earlier investigation of abnormal changes, helping the team plan preventative maintenance and minimise avoidable service disruptions.
