The ENERIS TROULESHOOTIN

STUDY OF THE NEED TO RAISE THE SHIFTFACTOR

Department proposes audit services for your electrical networks. The objective is to help you ent the main characteristics of yourindustrial, tertiary or infrastructure networks, anae remmen the parameters liable to causedysfunctions or excessive loads on installations and solutions to meet the needfor energy quality.
â–  Evaluation of the shift factor (cos ) with theactivation of different load types
â–  Study of the need to raise the shift factor to avoid penalties during the period of reference Aut te eetra netrs nur nstaatn anass rm n-ne te HVLV sstem tru tur termna strutn sstem

Audits & Troubleshooting

STUDY OF HARMONIC POLLUTION

â–  Measurement of harmonic pollution and evaluation at different points in the electrical distribution system
â–  Correlation with start-up of loads causing disturbances

ENERGY QUALITY

â–  Overview of harmonic pollution on a cycle representative of the site's load profile
â–  Measurement of energy quality parameters and compliance with the levels required by the EN 50160 standard
â–  Recommendation of filtering solutions
â–  Evaluation of non-standard parameters and analysis of the hazard which they represent for downline installations and loads

STUDY OF LOAD PROFILE

â–  Energy overview of the site with study of the energy components over a significant load period
â–  Evaluation of the interconnection parameters overseveral integration periods, for measurement periods of up to one week
â–  Evaluation of the load level on the site's HV/LV transformers and any overloading
â–  Evaluation of the load profile observed and the threshold effects on the tariff contract

STUDY OF COMMON-MODE COMPONENTS

â–  Measurement of the common-mode currents liable to cause untimely tripping
â–  Measurement of the common-mode voltages liable to cause malfunctions of sensitive downline loads
