Chauvin Arnoux Portable Test and Measurement Instruments In 1893, Raphael CHAUVIN and René ARNOUX joined together to found CHAUVIN ARNOUX. 120 years later, the adventure continues and the firm is now the parent company of the CHAUVIN ARNOUX  Group, specialized in the measurement of electrical and physical quantities.

Chauvin Arnoux History

Electricity is a crucial type of energy at the heart of our daily lives. It has to be deployed and distributed while guaranteeing user safety and its consumption has to be controlled with regard to costs and environmental concerns.

Designing, manufacturing and commercializing measuring instruments has been our core business for more than a century, allowing professionals to check and test the reliability, safety and efficiency of electrical distribution systems and the equipment connected to them, on a daily basis.

Proud of our two brands, CHAUVIN ARNOUX® and Metrix®, we propose a wide range of measuring instruments used by millions of professionals every day, all over the world. Our offering covers the fields of general electrical measurement (testers, multimeters and current clamps), electrical safety testers, wattmeters and electrical network quality analysers, oscilloscopes and, more generally, instruments for testing electronic devices and measurement of physical parameters.

Although its historical base is in France, CHAUVIN ARNOUX is now present worldwide, either via its subsidiaries (USA, Italy, China, UK, Sweden, Germany, Austria, Spain, Lebanon, Switzerland)  or, in the other countries, via its export sales department which is backed by a vast network of specialized distributors. Drawing on their expertise, our sales teams and our partner distributors do their utmost to provide you with the necessary support to choose the right products for your needs.

CHAUVIN ARNOUX’s industrial policy is based on its three production sites in France for the manufacture of the sub-assemblies and products for the CHAUVIN ARNOUX® and METRIX® brands. A factory in the United States and another in China provide local customization and supply additional products for our range.

In accordance with the Group’s quality policy, CHAUVIN ARNOUX provides its customers with products which meet its commitments and comply with both the national and international standards, particularly in terms of safety, metrology and protection of the environment. This approach is formalized by ISO 9001 and ISO 14001 certifications.

Production – Transmission – Distribution and electrical installations

From Production to Consumption

The electrical energy consumed in the industrial, tertiary and residential sectors comes from a technical chain comprising:

• Thermal, hydroelectric, nuclear, solar or wind power plants.
• A system for transmitting and distributing this energy via high-voltage and then low-voltage networks.
• An electrical installation in a building.

The main challenge for this technical chain is to ensure a safe, reliable supply of electrical energy, i.e. in compliance with the standards. To ensure that this quality of service is achieved, the actors in the sector perform a large number of measurements when commissioning or carrying out preventive and corrective maintenance. Chauvin Arnoux has a broad offering of measuring instruments specially designed for these operations.

Electrical Safety

Electrical safety from the distribution network through to the installation in the building is a major issue in terms of protecting people and property. This field, closely controlled by standards, recommends or requires checks on essential characteristics of the earthing circuit, insulation resistance, continuity of the conductors and the protective systems.

Electrical Power Quality

The quality of the electrical power distributed is a crucial technical feature for ensuring optimum operation of an electrical installation. It is measured by determining whether there are disturbances and abnormal events on the voltages, currents and frequencies.

The source of these electrical anomalies may be the usage segment (distribution system or electrical loads on the consumer’s side) or the supply segment. A deterioration of the electrical power quality may cause production losses or shutdowns and higher energy bills linked to the consumption profile.

Chauvin Arnoux’s Qualistar+® network and power analysers measure all the voltage and current parameters for electrical power quality diagnostics. The functions of these instruments can be used to acquire and record simultaneously all the parameters concerning transients, alarms and waveforms which can then be analysed with the DataView® software.

General low-voltage Electrical Measurements

In the field, it is more efficient to perform simple, on-off tests or measurements allowing rapid diagnosis. For this, professionals use a multimeter because of its universal capabilities and measurement ranges, or a multimeter clamp, which allows them to determine the current values in total safety, without contact or mechanical operations on the installation or the conductor.

It is crucial to select these two types of instruments carefully in order to achieve a pertinent diagnosis.  Taking advantage of its long experience, Chauvin Arnoux commercializes a wide range of products offering acknowledged functions, safety and rugged design.

Diagnostics & Inspections

Guaranteeing the safety of people and property and identifying potential savings are two important issues for our companies.

Objectives

Whether they are performed during commissioning or periodically, the aim of these operations is to establish:

• Compliance with the applicable regulations; such compliance is usually mandatory.
• An assessment of performance according to a standardized procedure; in this case, the threshold values are not necessarily defined.

Diagnostics and inspections are mainly performed by organizations which are independent (of the manufacturer and the customer-user) and possess appropriate authorizations. Each country defines a set of specific regulations requiring inspections to ensure that they are implemented. In addition, separate voluntary operations are performed to diagnose the performance or safety of a system.  These diagnostics and inspections generally use two types of analysis: visual checks and tests. The tests necessarily involve measurements.

Chauvin Arnoux offers measuring instruments capable of performing these measurements in the following cases:

• Electrical safety of installations
• Electrical, safety of machines and switchboards
• Electrical installation inspections using thermography
• Inspections of the work environment
• Thermal diagnostics
• Energy diagnostics

Electrical Safety of Installations

The electrical safety of installations, whether residential, industrial or tertiary, is crucial for guaranteeing the safety of the people present and the premises which they are in. At the end of the construction works, after modifications or periodically (preventive action), these inspections can check:

• The electrical continuity of the protective equipotential of the mechanical chassis-earths
• The sizing and operation of the protective systems
• The effectiveness of the earthing system
• The quality of the electrical insulants

The IEC 60364 international standard is one of  the technical standards defining the rules for the design and construction of a low-voltage electrical installation, as well as the tests for ensuring the finished installation’s compliance with the rules.

Bi-function or multi-function installation testers can be used to perform the tests specified in many international and national standards (such as NF C15-100 in France, BS 7671 in the UK, VDE 100 in Germany, etc.).

Electrical Safety of Machines and Switchboards

Like electrical installations, electrical machines and switchboards are also subject to regulations designed notably to ensure that they can be used safely. These standards define the type qualification tests (marketing conditions), the commissioning tests (first use) and any periodic testing that needs to be carried out.

Electrical installation inspection using thermography

Alongside the measurements of electrical quantities on installations or machines, it may be useful to carry out a thermographic inspection. For example, in France, the APSAD D19 technical document defines the…Read More
