Highly available and reliable utility communication

Technology shifts in utility communication

IEC 61850 instead of copper wires for truly digital integration of utility communication equipment

Using the benefits of IEC 61850 to communicate across substations

Move from TDM to packet-switched communication for operational, maintenance and protection data

Utility-grade equipment to ensure the reliable operation of the power grid is required

Asset Performance Management (APM)

Increased number of assets with fixed operation & maintenance budget

Assets Asset Management Drivers Asset Management Challenges

•Digital workforce less attracted to Asset Intensive Industries

•Younger Workforce have different expectations and a lower threshold

Aging Workforce

• Regulatory pressures to improve environmental, reliability and safety standards

Aging Assets

•Need to do more with less

• Improve return on assets without impacting production/service delivery
