UL Standard for Safety for Insulation Coordination Including Clearances and Creepage Distances for Electrical Equipment These requirements cover an alternate approach to specifying through air and over surface spacings for electrical equipment through the use of the principles of insulation coordination.
Apr 14, 2013· Creepage distance can also be refer as leakage distance for insulators. Insulators in substation are provided to avoid any leakage current from live electrical conductors to flow to the earth through supports. The atmospheric dust sticks to the insulator surface forming a conducting layer.

- UL840 Insulation coordination including clearances and creepage distance for electrical equipment Besides equipment level specifications there are component level standards. Table 2.3 shows the important specifications on component level. The equipment level specification can reference the component level specification as a subordinate document.
An electrical insulator is a material whose internal electric charges do not flow freely; very little electric current will flow through it under the influence of an electric field. This contrasts with other materials, semiconductors and conductors, which conduct electric current more easily.
Creepage Distance. Creepage (Leakage distance) is 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. A proper and adequate creepage distanceprotects against tracking, a process that produces a partially conducting.
Creepage distances are measured by the operating voltage, the characteristic of the insulants (CTI value), the expected contamination level as well as the preventive measures against contamination. Basis of the creepage distance is the rated voltage derived from the operating and / or system voltage.
Creepage and Clearance Distances in Electrical Equipment for Shipboard Use Abstract: The influence of a number of ionic liquid contaminants and of some oils upon the tracking behavior of three typical insulants, (phenolic-bonded paper board, cellulose-filled alkyd molding and glass-filled polyester dough molding compound), is measured in terms ...
