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.
