INTRODUCTION
Line Leakage tests use impedance models called measuring devices (MD’s) to measure
how much leakage current is being produced by a DUT under several conditions: normal,
reversed input polarity, open neutral, and open ground. Performing a Line Leakage test
gives manufacturers the opportunity to know how much leakage current a user will be
subjected to under a variety of different circumstances.
Line Leakage testing is commonly performed as a design/type test during new product
development. Configuration “G-L” represents an earth leakage test which measures the
leakage current from the DUT’s protective earth ground back to the system neutral.
Why Perform a Functional Run Test….
Functional Run testing, although not considered to be an electrical safety test, is
worthwhile to perform for a variety of reasons. The Functional Run test is primarily used
to determine if a DUT runs properly after it has been subjected to a battery of electrical
safety tests. Usually the test monitors various parameters including: input voltage, input
current, input power, and input power factor. Test operators can use the information
gained from the Functional Run test to determine if a DUT is operating properly before
the unit is shipped to a customer. This is beneficial since there is no electrical safety test
that can conclude if a product will power up and operate properly.
