Why use PowerLogic System?
Benefits and applications
Reduce energy costs
DB103446
PowerLogic System helps you reduce power consumption and
the cost of the energy you use through sub-billing and electrical
contract optimisation.
E87260
Sub-billing and cost allocation
to reduce consumption
Metering of energy consumption to:
b identify major consumers
b allocate costs
b make users aware of expenditures.
Optimisation of power contract and load curves
to reduce energy costs
Recording of energy consumption and load curves to:
b optimise the power contract
b aggregate multi-site costs and negotiate global contracts
b identify spare capacity for electrical installation extensions
b manage peaks and avoid penalties:
v improve power factor by power factor correction solutions
v avoid subscribed-power overruns by automatic load-shedding.
Monitoring of other utilities
Count pulses received from other utility meters (water, gas, steam, etc.) for global,
centralised utility management.
Organisation of measurement data
E88058
Trend curves
Improve power quality
DB103448
Power quality has a direct impact on operating costs:
b direct costs: over-consumption due to increased power losses
b indirect costs:
v production losses: process malfunctions, unnecessary tripping
v equipment costs: shorter service life, lower efficiency,
oversized equipment.
E87257
PowerLogic System lets you assess the quality of your power, identify the causes
of any problems and check the effectiveness of remedial measures.
Four main functions are used to check power quality:
b monitoring of harmonics
b detection of voltage sags and swells
b detection of transients
b EN50160 electricity supply compliance checking.
Spectral analysis of harmonics
