Creepage And Clearance Test Card IEC 60598-1 For Measured Surface Of The Insulation
Product Information:
These test gauges conform to IEC 60598-1 clause 8.2.1, clause 11.2, and IEC60335-1 Clause 29 etc. They are used to determine the shortest path between two conductive parts, or between a conductive part and the bounding surface of the equipment, measured along the surface of the insulation, with specifications made according to the requirements.
Features:
A creepage distance test card, also known as a creepage and clearance test card, is a specialized tool used to measure and verify the creepage and clearance distances in electrical insulation systems. Creepage distance refers to the shortest path along the surface of an insulating material between two conductive parts, while clearance distance refers to the shortest distance through air or other insulating medium between two conductive parts. These distances are essential for ensuring the safety and reliability of electrical equipment, particularly in high-voltage applications. Here are the key features and functions typically associated with a creepage distance test card:
Measurement Scale: The creepage distance test card features a measurement scale printed on its surface. This scale typically includes markings in millimeters (mm) or inches (in) to allow for accurate measurement of creepage and clearance distances.
Markings and Patterns: The card may have specific markings or patterns that help assess the creepage and clearance distances. These markings can include parallel lines, grids, or other geometric patterns that facilitate measurement along the surface of the insulating material.
Material and Size: Creepage distance test cards are usually made of non-conductive materials, such as plastic or fiberglass, to prevent interference with the measurements. The card is typically small and compact, making it easy to handle and use in confined spaces.
Compliance with Standards: Creepage distance test cards are designed to comply with industry standards and regulations, such as those specified by IEC (International Electrotechnical Commission) or UL (Underwriters Laboratories). They are manufactured and calibrated to ensure accuracy and consistency in measuring creepage and clearance distances.
Application: To use a creepage distance test card, it is placed on the insulating surface between two conductive parts, such as two electrical terminals or components. The card is aligned along the shortest path, and the creepage and clearance distances are determined by observing the point where the measurement scale intersects the conductive parts.
Creepage distance test cards are widely used in electrical and electronic industries during the design, manufacturing, and testing stages of electrical equipment. They help ensure compliance with safety regulations and standards by verifying that the creepage and clearance distances meet the required specifications. Proper creepage and clearance distances are crucial for preventing electrical arcing, flashovers, and insulation breakdown, minimizing the risk of electrical accidents and ensuring the reliable operation of electrical systems.
