Chauvin Arnoux C.A 6505 5 kV Industrial Insulation Resistance Tester

Overview

The Chauvin Arnoux C.A 6505 is a top-tier insulation resistance tester (megohmmeter) engineered for industrial maintenance professionals, electrical engineers, and procurement teams who need precision and reliability under harsh field conditions. Housed in a site proof, shock-resistant casing with IP53 protection, it delivers both fixed and programmable high DC voltages, accurately measures very high insulation resistance, and integrates additional diagnostics like DAR and PI to help assess insulation condition, age, and safety. Whether you’re testing motors, transformers, cable trays or generator windings, the CA6505 is built to meet international standards and deliver consistent, meaningful data.

Key Features

• Wide Voltage Flexibility: Fixed test voltages at 500 V, 1,000 V, 2,500 V and 5,000 V DC, with extended programmable range from ~40 V up to 5,100 V DC.

• Large Insulation Resistance Range: From 10 kΩ up to 10 TΩ, enabling detection of even very slight insulation degradation.

• Advanced Diagnostic Ratios: Automatic calculation of DAR (Dielectric Absorption Ratio) and PI (Polarization Index) to facilitate insulation health monitoring and predictive maintenance.

• Additional Measurements: Voltage detection, capacitance, leakage/residual current measurement to give full picture of insulation system behaviour.

• User-Friendly Display: Large backlit LCD with bar graph for easy reading of realtime values; intuitive interface for selecting voltages and test durations.

• Robust Safety & Compliance: Designed to meet IEC 61557, IEC 61010 standards, with 1000 V CAT III rating, and IP53 enclosure to withstand site conditions.

• Portable & Reliable Power: Operates on rechargeable NiMH battery, with long battery life under normal usage; supports mains charging.

Applications

• Preventive maintenance of electrical installations: motors, generators, transformers

• Verification of insulation integrity in cables, switchgear, and windings

• Electrical testing in utility plants, power distribution, industrial processing facilities

• On-site diagnostics and commissioning of HV equipment

• Quality control in manufacturing of insulation systems

【FAQ】

Q1: What voltage ranges does the CA6505 support?
A1: It supports fixed test voltages of 500 V, 1,000 V, 2,500 V and 5,000 V DC. Additionally, it can be programmed from approximately 40 V up to 5,100 V DC for flexible testing.

Q2: How high can its insulation resistance measurement go?
A2: CA6505 measures from 10 kΩ up to 10 TΩ, allowing detection of very high insulation resistance and early insulation deterioration.

Q3: Does it calculate DAR and PI automatically?
A3: Yes. The instrument automatically computes the Dielectric Absorption Ratio (DAR) and Polarization Index (PI) when tests are conducted over the necessary durations.

Q4: What safety and protection features does the CA6505 have?
A4: It meets IEC 61557 and IEC 61010 standards, has a CAT III 1,000 V safety rating, IP53 rugged enclosure, and includes a safely-designed discharge after testing.

Q5: What is included with purchase?
A5: Comes with measurement leads, safety leads, crocodile clips, mains power lead, carrying bag, and multi-language user manual.
