7630 Touch Current Tester Eec Extech Electronics Co Ltd The leakage test on class ii equipment is referred to as a touch current test. many test instruments also have a substitute or alternative leakage test. the substitute leakage test applies a reduced ac voltage, typically 40 60 vac, between the line and neutral joined together and the earth conductor, or test lead for class ii equipment. A touch current test for class ii appliances is carried out as class ii appliances do not have an earth. there are two different methods of testing procedures that can be used. one is a probe test where an earth bond lead is used as a probe to measure any current leaking onto the enclosure or casing. Touch current test. the touch current test is identical to the earth leakage test except for one important aspect. since class 2 appliances do not have an earth connection, the test lead is connected to an exposed metal part. it is called the touch current test as it measures the current that would flow through a person if they were touching. Introduction to electrical safety testing: part i.
Touch Current Testing 101 Webinar Youtube Touch current test. the touch current test is identical to the earth leakage test except for one important aspect. since class 2 appliances do not have an earth connection, the test lead is connected to an exposed metal part. it is called the touch current test as it measures the current that would flow through a person if they were touching. Introduction to electrical safety testing: part i. 7. touch current test. imagine touching an appliance and getting a mild shock. the touch current test measures the current that might pass through a user if they touch the appliance. this is especially vital for equipment where the leakage current might be higher but within defined limits. This paper reviews a demonstra on showing the setup. and conditions for making proper touch current. measurement for some products with emphasis on the. proper procedure and interpreta on of.
