Customer analysis

Apparent, active and reactive power analyses

Customers may find themselves in an uncomfortable situation due to their electricity consumption, which, being close to the power limits subscribed to by their energy supplier, can lead to all kinds of malfunctions in their electrical installations. On the other hand, the reactive power consumed by customers' electrical installations results in the invoicing of energy that could be compensated for. It also results in the invoicing of electrical penalties because it contributes to the overloading of EDF lines.
Our power analyses enable us to :

• Check the level of saturation of the electricity network (the customer's power source)
• Check the compatibility of the electricity contract signed with the energy supplier with the customer's electricity consumption requirements
• Check that the customer's HV/LV transformer is compatible with the customer's electricity consumption requirements
• Size the reactive energy compensator (active filter or capacitor bank)
• Check the electrical behaviour of an electrical installation (inrush currents, voltage drops, electrical disturbances, etc.)

Analysis of electrical pollution (current harmonics)

The latest generations of electrical/electronic equipment generate more pollution on the electricity network (current/voltage harmonics). Harmonic currents have a frequency that is a multiple of the fundamental frequency 50Hz (mainland France), and these can lead to malfunctions in the customer's electrical installation, particularly in industrial processes, cause overheating in wiring or electrical cabinets, cause damage to sensitive electrical/electronic equipment and generally contribute to the premature ageing of electrical/electronic components.

Our power analyses enable you to :

• Check the level of electrical pollution present on the customer's installation
• Define the disturbing current harmonics within the customer's electrical installation
• Define the means of combating and compensating for harmonic pollution on the customer's premises
• Reduce or cancel the consumption of harmonic currents

Analysis of Watt/hour energy consumption and electricity network quality.

Optimising electricity consumption has become a major issue these days. Electrical installations or part(s) of electrical installations may need to be measured before they can be optimised. Our analyses can also be used to :

• Check the quality of the electrical network in accordance with standard NF EN 50160
• Record electrical events such as voltage dips and power cuts, etc.

Analysis of battery banks

Safety power supplies such as inverters, central safety sources and uninterruptible power supplies of all kinds have a storage battery to ensure continuity of service for equipment sensitive to electrical disturbances. It is therefore essential to check these batteries, whatever the technology used, to guarantee the autonomy of safety power supplies. Our battery analyses can be used to

• Diagnose the degradation of one or more cells in a battery
• Prevent the ageing of an accumulator battery using measurement equipment dedicated to these electrochemical components (impedance, temperature and e.m.f. measurements, etc.).
• Determine the autonomy of the battery reserve
