Optimisation of the electrical network : costs
„ Reduce energy cost
†
Monitor load curve
-> implement load-shedding
schemes
-> concentrate heavy consumption
during off-peak times
-> avoid exceeding stipulated
limits
†
Monitor power factor
-> implement reactive
compensation schemes
†
Optimize utility contract
& avoid penalties
„ Monitor load curves
4
Optimisation of the electrical network : costs
„ Reduce energy cost
†
Sub-metering / cost allocation
-> allocate internal cost
-> implement awareness programs
(best practices, peak shaving)
†
Multi-sites aggregation
to negotiate better rates
„ Allocate energy costs
5
Optimisation of the electrical network : costs
„ Optimize investment
† Identify spare capacity
through analyze of Energy usage
† Optimize safety margin
between installed Power and
demand Power
† -> avoid unnecessary investment
when modifications or extensions
are required
„ Extend equipment life time
& reduce losses
through Power quality improvement
(cables, transformers, capacitors, motors,
electronics...)
„ Analyse energy usage

& Current unbalance
† Voltage or Current unbalance
† Frequency

Optimisation of the electrical network : quality
„ To avoid
† Increased losses in cables &
transformers
† Equipment destruction or reduced
life time due to overheating
(transformers, capacitors, motors,
VSD’s, neutral cables…)
& vibrations (motors)
† Untimely CB tripping
† Process disturbance
(sensitive equipment: relays, VSD’s,
PLC ’s, motor speed instability...)
† Perturbation of communications
†
& to check energy supply compliance
„ Monitor currents & voltages

Optimisation of the electrical network :
availability
„ Help for preventative maintenance
-> detect problem early
-> avoid shut down
-> minimize production losses
†
†
†
†
†
„ Alarm on key parameters & record events
Alarming on key parameters
Number of CB O/C operations
CB contact wear
Identify polluting loads
(high level of Harmonics)
& pull them apart from sensitive
loads, install filters or even change
them
Balance bus-bars after demand
Power analysis

Optimisation of the electrical network :
availability
„ Help for corrective maintenance
-> minimize down time
-> minimize production losses
Look at Sequence of Events
Recording, Waveform captures…
† Identify origin of problems :
- internal cause
- or problem coming from Utility
† Check Voltage disturbances,
overloads...
