The replacement kit from Chauvin Arnoux is specifically designed for use with PEL power analysers and Qualistar network analysers featuring 4 voltage measurement inputs. It serves as a replacement or supplement for measurement leads and accessories required for voltage measurement in electrical installations. The kit enables safe, precise, and efficient measurement in the field of electrical engineering, particularly in industrial and commercial applications where high safety requirements apply.

Applications
This kit is designed for voltage measurement in electrical networks, particularly in installations classified as CAT IV. This category includes measurements at the primary side of distribution transformers, supply lines to distributors, and main lines in buildings. The measurement leads are therefore suitable for use in high-voltage environments where high insulation strength and safety are required. Typical applications include maintenance, servicing, and diagnosis of electrical systems.

Functions and Equipment in Detail
The kit includes 4 measurement leads, each 3 m long and black in colour. The leads are rated for a maximum voltage of 1000 V and comply with safety category CAT IV, ensuring high insulation strength and protection against electrical overvoltages. The maximum current load capacity is 15 A, sufficient for most standard measurements. At each end of the leads, straight banana plugs (4 mm) are fitted, enabling secure connection to the measurement inputs of the analysers. Additionally, the kit includes 4 crocodile clips, allowing quick and secure attachment to wires or terminals in the installation.

Technology Explained Simply
The designation CAT IV refers to the safety category according to IEC standards, which defines the maximum permissible voltage and environmental conditions for measuring instruments. CAT IV applies to measurements at the energy supply level, such as at distribution transformers or main lines. The measurement leads are therefore designed for use in high-voltage environments where a high protection standard is required. The length of 3 m provides sufficient manoeuvrability during measurement without being excessively long, which facilitates handling. The black colour is standard in electrical engineering for measurement leads, enabling clear visual distinction from other wires.

Compatibility and Accessories
The kit is specifically designed for PEL power analysers and Qualistar network analysers with 4 voltage measurement inputs. The measurement leads are equipped with 4 mm straight banana plugs, which fit directly into the corresponding inputs of the devices. Additionally, the kit includes a set of 12 coloured identification parts for marking measurement leads, current transformers, and measurement inputs. These identification parts facilitate the assignment of individual leads and reduce the likelihood of incorrect connections during complex measurement tasks.

Installation and Mounting
Installation is carried out by simply connecting the measurement leads to the measurement inputs of the analyser and attaching the crocodile clips to the wires or terminals to be measured in the installation. The crocodile clips allow for quick and secure connections without requiring additional tools. The identification parts can be directly attached to the leads or to the device inputs to ensure clear assignment.

Operational Advantages
Using this replacement kit provides high safety during voltage measurement, as the leads comply with CAT IV category and are therefore suitable for use in high-voltage environments. The 3 m length of the leads offers sufficient manoeuvrability, while the crocodile clips enable quick and secure connections. The coloured identification parts reduce errors in assigning leads, especially during complex measurement tasks with multiple inputs. The kit is thus a reliable addition for the maintenance and diagnosis of electrical installations.

Scope of Delivery
The kit includes 4 measurement leads (black, 3 m, 1000 V CAT IV, 15 A), 4 crocodile clips, and 1 set of 12 coloured identification parts.
