Surge & Impulse Test
|CTL has Surge Test Facility upto
10KVA & Impulse Test Facility having different waveshapes like
1.2/50 Âµs, 10/700 Âµs etc. These tests are covered under the following
Indian and International standards: IS 616, IEC 60065, IS 13252, IEC
60950, IS 302 etc.
|To represent surges generated
due to lightning, the IEC Standard impulse wave of 1.2/50s wave is
generally used. By the use of spark gaps, conditions occurring on the
flash over to line are simulated. The total duration of a single
lightning strike os about 100s, although the total duration of the
lightning stroke may be a few seconds.
These tests relate to the immunity requirements for equipment to unidirectional surges caused by overvoltages from switching and lightning transients. Several test levels are defined which relate to different environment and installation conditions. These requirements are developed for and are applicable to electrical and electronic equipment.
