    Hello All,

    Im looking for advise on how to create an ELCB trip time tester.
    I need to measure how long does the voltage discharging from 240V to 0V.
    Does any one have any idea how does the tester works?

    You would need to setup a timer monitor of some kind and set a deliberate earth fault and measure it, I don't know of anything that would do it off the shelf.

    Im thinking of using Microcontroller to measure the voltage when i press a "test" button. But im worry that the voltage discharging time may delay cause microcontroller may take sometime to react. Therefore i was thinking any electronic component can make the tester easier...
