Megger EV adapter

lyledunn

The Megger EV adapter has a proximity pilot selector that ranges from N/C to 63A. Presumably it places a particular resistance across PP and PE to mimic the cable capacity but I am at a loss as how to use it. I am thinking that one might need to connect an oscilloscope to view the PWM. I have contacted Megger but no reply as yet.

    That link didn’t open Mike. Just thinking that perhaps unless the PP selection is correct for the charger output, then it might not pull the contactor in. So, for example, a 32A untethered charger will not deliver through a 16A lead.

    Thanks Mike. What I refer to is at the top of page 9. So you plug the adapter in, turn the PP selector knob, then what?

    Check that the contactor in the charger goes 'klunk' and that LN and E then have their normal voltages and Zs and RCD functions by plugging your multi-test or whatever into the 13A test socket on the adapt or at least I think so - all the extra trick stuff is just to get the charger to think there is a real car there.

    The other pins are for future expansion by other bits of testgear you do not have, for more detailed charger  tests that as yet BS7671 doe snot require.

    Mike.
