When Maintenance Fails, Consequences Multiply
Failure in maintenance leads to significant issues:
- Production stoppage, loss of turnover
- Urgent repairs with costs 2 to 5 times higher than planned maintenance
- Safety risks, incidents, and accidents
- Machine damage, sometimes irreparable
- Lost customers, delays, and missed deadlines
- Affected quality, rejects, and non-conformities
Impact of Maintenance Failures: Up to 10% of turnover can be lost due to maintenance issues.
Predictive maintenance is presented as a high-performance solution, aiming to recover the 10% potential loss and maintain 90% operational turnover.
Chauvin Arnoux instruments are designed to last and act, ensuring reliable performance.

Megohmetry - Fundamental Notions
The Megohmmeter is used for measuring electrical insulation resistance in motors, cables, transformers, etc. It applies high voltage (500 V, 1 kV, 5 kV) to detect current leakage. DAR, PI, and DD indices are time-based reports used to assess insulation condition over time, indicating cleanliness, humidity, or degradation.
1. DAR (Dielectric Absorption Ratio)
DAR = Insulation resistance at 1 min / at 30 s. Used to detect humidity or contamination, especially for small equipment or quick tests. A typical value of ≥ 1.4 indicates good insulation, while < 1.25 suggests questionable insulation.
2. PI (Polarization Index)
PI = Resistance at 10 min / at 1 min. Evaluates the insulator's ability to polarize and block leakage currents. It is more reliable than DAR for thick insulation (e.g., high-voltage motors, transformers). A typical value of ≥ 2.0 indicates good insulation, while < 1.0 suggests degraded or wet insulation.
3. DD (Dielectric Discharge)
Measures depolarization current after voltage removal. Used to detect conductive contamination or insulation aging, even if PI is good. Expressed in μA or residual current, it is used in advanced analysis, particularly for transformers.
Why measure these reports? These reports allow for the detection of slow or hidden degradation, consideration of environmental factors (temperature, humidity, dirt), and comparisons over time for preventive maintenance, unlike simple resistance measurements.
A graph illustrates insulation resistance over time, showing a decrease due to aging (period A), a rapid drop indicating a defect (period B), and recovery after repair (period C).
CA 6549: 5 kV Insulation Controller
Test Insulation, Secure Installations
In industrial environments, insulation failure can cause production stoppages, critical failures, or safety incidents. The CA 6549, an insulation controller up to 5 kV, is designed to meet these challenges with precision, robustness, and reliability. It offers a complete, reliable, and durable analysis of high-voltage equipment, serving as an indispensable tool for preventive and predictive maintenance.
Designed for maintenance professionals:
- Anticipating invisible failures: Detects progressive or hidden insulation deterioration before it becomes critical.
- Real conditions considered: Provides reliable results even in harsh industrial environments (humidity, temperature).
- Facilitated preventive maintenance: Track measurement evolution and identify aging signs before incidents occur.
With the CA 6549, transition from a repair logic to an anticipation strategy for fewer failures and more availability.
CA 6240: Microohmmeter
Precision at the heart of electrical maintenance
Measure, Control, Secure
The CA 6240 is a precision micro-ohmmeter, essential for industrial maintenance operations requiring the measurement of very low electrical resistances. Compact, robust, and easy to use, it efficiently accompanies users in the field, workshop, or laboratory.
An essential instrument for industrial maintenance:
- 1. Electrical Connection Control: Detects faulty contacts on terminals, busbars, and cable joints. Identifies potential heating points related to abnormal contact resistances. Verifies tightness after installation or intervention to prevent future failures.
- 2. Power Equipment Maintenance: Provides precise analysis of contacts in circuit breakers, disconnectors, and contactors. Detects wear of internal components without disassembly. Prevents failures related to high contact resistances that can lead to critical heating.
The CA 6240 guarantees reliable connections, safe equipment, and optimized preventive maintenance, representing an essential investment for improving the availability and performance of electrical installations.
CA 6472: Earthing Controller
Control Earthing, Secure Installations
In any industrial environment, a reliable earthing system is crucial for personnel safety, equipment protection, and operational continuity. The CA 6472, a versatile and high-performance earthing measurement device, allows users to diagnose, control, and anticipate any earthing defect.
Why integrate the CA 6472 into your maintenance strategy?
- 1. Checking Earthing System Efficiency: Precisely measure earthing resistance to ensure safety thresholds (< 10 Ω) are met. Perform periodic regulatory checks (NFC 15-100, IEC 60364). Validate conformity of new or renovated installations.
- 2. Preventing Electrical Risks: Enhances personnel safety (a faulty earth can impair residual current devices). Protects equipment against surges or leakage currents. Reduces fire risk by correctly evacuating ground faults.
- 3. Time Monitoring for Predictive Maintenance: Track earth resistance evolution to detect invisible deterioration (corrosion, conductor breakage, improper burial). Anticipate interventions before critical failures and guarantee business continuity.
With the CA 6472, move from a simple compliance check to a true risk prevention strategy, ensuring safety, reliability, and performance through correct measurement.
