Energy market
From production through to use, energy has to be monitored by fixed measuring systems. At the same time, everyone working on this chain, from production through transmission to distribution, must be equipped with measuring tools.
Thanks to the products in their catalogues, Chauvin Arnoux and Chauvin Arnoux Energy offer solutions for most of the requirements and concerns of the people working in the field.
Testing the insulation, checking earthing networks, including in complex situations such as networks of electricity pylons, measuring power values, recording energy values, detecting hot spots by means of infrared thermography, detecting voltages (or checking that they are absent), analysing the waveforms of electrical or electronic sognals, etc.
Chauvin Arnoux is familiar with and has mastered all these applications, offering ideal solutions using its products designed and manufactured in France to ensure efficiency, safety and quality.
Similarly, the measurement, accounting and control of energy consumption is a crucial parameter integrated in the design of the performance solutions developed and marketed by Chauvin Arnoux Energy.
Sustainable energy management is a major challenge for the societies of the future. This requires the development of nuclear energy, the principal source of electricity production in France (78%), hydroelectric power (10%) and new energy sources. Pyrocontrole is a leading player on the nuclear market, proposing an offering of qualified temperature sensors specially developped for this market.

Nuclear energy
Clean or renewable energy sources
Renewable energy accounts for 886 MW in France (excluding hydroelectric power). In the context of sustainable development, the share of renewable energy sources has grown considerably in the last few years. These sources include solar energy, rolled out both in homes and on production sites with greater capacity (solar farms). These installations use photovoltaic panels to transform solar energy into electricity.
To check the efficiency of these installations and test the solar panels, Chauvin Arnoux Test and Measurement offers solar-panel testers totally dedicated to this application:
- The Green Test FTV 100 solar power installation analyser provides a survey of the electrical power values and calculates the efficiency of the solar panels and the DC/AC inverter.

- The FTV 200 is an instrument which tests solar panels.
Chauvin Arnoux Energy and wind power
A sector long reserved for national weather services, transport and Defence, wind measurements are now sought by many professionals in the agriculture, tourism and leisure industries. Wind measurement systems designed at the request of the French Navy are fitted on all French warships. TAVID anemometer-vane units are installed in the national weather service's observation stations. They are also used by EDF the French nuclear authority (CEA) in the anti-pollution systems of nuclear sites. SNCF uses them on TGV high-speed rail lines to protect the large parabolic antennae in the event of storms.

An economic necessity
Precise analysis of the electrical network to track disturbances affecting the operation of electronic equipment
The quality of electricity is a strategic concern for energy suppliers, staff maintaining or managing tertiary or industrial sites and electrical equipment manufacturers.
The cost of disturbances (outages, voltage dips, harmonics, voltage surges, etc.) may be particularly high and cause significant financial losses: production shutdowns, wastage of raw materials, malfunctions of lighting, computers and security systems which may threaten people's safety (hospitals, airport lighting, etc.). This means it is important to optimize the operation of electrical installations by detecting any electromagnetic disturbances liable to affect the operation of industrial equipment and processes.
Often implemented following operating incidents or malfunctions, corrective measures can only be applied after precise analysis of the electrical network:
• Collection of the network information (types of loads, ages of the components, etc.)
• Identification of the equipment affected by the disturbances
• Environmental conditions (humidity, dust, temperature, etc.)
• Installation of fixed measuring equipment for constant monitoring of the installation in order to detect and record the event which originally caused the problem (threshold overshoots, waveforms, harmonics, etc.).
Compliant with the EN 61000-4-30 Class A standard, the products in the MAP range record the relevant parameters and, by means of associated software, provide continuous, detailed and comprehensive analysis of the quality of the electricity supplied, in accordance with the applicable standards. Whether you choose a plug & play single-phase analyzer or permanent or non-intrusive three-phase analyzers, all these Chauvin Arnoux Energy products measure all the parameters of HV/MV/LV electrical networks.
The Enerium 300 power monitor can also be adapted for network analysis at the LV general switchboard (internal quality of the networks downstream from the point of supply). This power monitor is ideal for analysing events on the network (voltage dips, outages, surges, etc.) according to the EN 50160 standard.
Alongside all the measuring instruments, don't forget the current transformers!
The EN 50160 and IEC 61000-4-30 standards
For electrical power distributors, it is essential to supply a quality product, i.e. a voltage at 50 Hz (or 60 Hz), which is sinusoidal, three-phase and balanced below a rated value. This means the bill sent to the customer is consistent. To help distributors and users to monitor and improve electrical network quality, several standards have been established.
The EN 50160 standard specifies the principal quality characteristics of the voltage supplied by the MV and LV public distribution network at the point of supply: frequency, amplitude of the waveform, symmetry of the three-phase voltages during a predefined observation period. It indicates the limits or the values of the voltage characteristics which any customer has the right to expect.
Alongside this, the IEC 61000-4-30 standard was drafted to measure the various voltage quality parameters and obtain reliable, reproducible and comparable results, whatever the measuring instrument used and whatever the environmental conditions. This standard defines the measurement methods for each parameter and how to interpret the results. It also specifies the precautions to be taken when installing measuring instruments on live circuits.
Statistical view of the events in relation to the ITI templateQualifying power quality on the electrical network
Once the objectives have been clearly defined, you must:
• Measure the qualimetric parameters of the installation: voltage, frequency, unbalance, flicker, remote control signals, harmonics and interharmonics, voltage surges, etc.
• Capture the events: voltage dips and surges, waveforms, transients, peak detection, etc.
The solution chosen involves installing network quality analyzers which comply with the IEC 61000-4-30 Class A standard downstream from the power and current transformers (MV level) in order to measure the quality of the power coming from several points in the electrical network.
