Comparative Tracking Index (CTI) for Insulating Material group – IEC 60112
CTI is max voltage which material can withstands 50 water drops without without formation of conductive path.
CTI is max voltage which material can withstands 50 water drops without without formation of conductive path.
Internal Arc Protection ensures Personal and ASSEMBLY protection under arcing conditions due to low impedance path, cause of electrical explosion.
NFPA 70E establishes the default arc flash boundary at 4 feet for low voltage (< 600V) systems where the total fault exposure is less than
Arc Blast is the supersonic shockwave produced when the uncontrolled Arc vaporizes the metal conductors and expanding Plasma.
Current transformer Accuracy class is highest permissible percentage error at rated current for that accuracy class, as per IEC 61869-2 and IS 2705.
Severity Test for Assembly is Degree of impact a defect has on its operation, under conditions of high humidity combined with cyclic changes in temperature.
Degree of severity of burns is based on size and depth of the burn on human body. Fire, steam, Radiation, chemicals, Electric Arc, can cause burns.
Power Quality Standard help us define acceptable limits for which Equipments must be designed to work and beyond which mitigation must be implemented.
Clearance is shortest distance in air and Creepage is shortest distance along the surface of a solid insulating material, between two conductive parts.
