Why assets monitoring?

TECHNICAL CONSTRAINTS / TECHNICAL WEAKNESSES

  • Networks become more complex – renewables, fluctuating generation
  • Bi-directional power/load flow
  • More operations and stress on equipment: switching, overloads, harmonics
  • The infrastructure is aging, impact of new conditions on equipment is unknown
  • Environmental events are worsening (global warming)
EVOLUTION OF INDUSTRY GOOD PRACTICES
  • Digitalization, INDUSTRY 4.0 or SMART GRID
  • High availability and quality requests for the electricity supply (High risk of huge penalty for utilities and risk of financial losses for industrial customer in case of breakdown)
  • Higher requirements for security and safety

There are 5 to 10 arc flash explosions in electrical equipment every day in the USA

What are the main failures?

INCREASE OF THE TEMPERATURE
  • Connection faults
  • Harmonic
  • Overload
DEGRADATION OF THE INSULATION
  • Superficial Partial Discharge (PD)
  • Internal PD
  • Corona PD

Continuous Rising of temperature on critical points and Partial discharges represents 70% of failures!

What are the benefits of an asset monitoring?

The United States Department of Energy found that 75% of breakdowns are eliminated by energy companies that use asset monitoring solutions enabling access to predictive maintenances / condition base monitoring (CBM).
