In 1893, Raphael CHAUVIN and René ARNOUX joined together to found Chauvin Arnoux.
Enerdis, the expert in energy intelligence, is specialized in fixed equipment for measuring, monitoring and supervising electrical networks and energy systems.
120 years later, the adventure continues and today the company is an expert in the measurement of electrical and physical quantities in industry and the tertiary sector.
The company's original industrial and entrepreneurial spirit remains, but the Chauvin Arnoux Group's influence now covers the whole world. Its expertise is structured and promoted through four companies:
Differential Voltmeter to measure of the difference between voltage . Ammeter and voltmeter , Differential Double Voltmeter , 90 degrees analoge alternating voltage and current is one of the products .
The Electronic Synchroscope is designed to provide an illuminated indication of actual phase difference between the BUS Voltage(reference voltage) the GENERATOR Voltage(incoming & voltage) . this device has three potentiometer to adjust the phase difference , the voltage and time synchronization . When two alternators are paralleled it is necessary that ,1-Frequency must be equal . 2-Phase must be same .
versatile meters with the ability to measure 3 to 110 parameters, the opening and closing contacts for control and alarm of the high and low values, has a special place in the panel. Also it can be used for harmonic analysis.
