In principle IEC 60601-1 also considers the region up to 60Vdc as safe for the operator, while >0.1V is potentially unsafe for direct contact with a patient (e.g. via electrodes or catheter).

Dec 07, 2015 · Creepage Distance for Insulators: The creepage distance for insulators is the shortest distance along the insulator surface between the metal parts at each end of the insulator. 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.

Answer Posted / deadzg_devil Creepage Distance. Creepage 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.

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 Distance: An important consideration in determining the insulation in a sub-station, particularly if it is located near sea or a thermal power generating station or an industrial plant is the level of pollution. As a first step to combat this problem special insulator .

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.

consists of the distances between voltages. The base standard for medical electrical equipment, IEC/UL 60601-1, specifies air and creepage distances of at least 3 mm between energized parts of different polarities and 4 mm between energized conductors and earth. Care .

Dec 31, 2015 · Answer: Creepage distance is the shortest distance between two conducting points along the surface of the insulating material.

For example, the minimum creepage distances and air clearances providing MOPP for working voltage of 17 V is 1.7 and 0.8 mm, respectively, for one MOPP. For two MOPP, the creepage distance is 3.4 mm and air clearance is 1.6 mm [152]. Another concern regarding electrical medical devices is .
