Testing Ex display

[STUMANN73]

Hi all i'm after some advice please,

I was trained as a pat tester for my company a few years back (10 years)to test ex display lamps ect ect, we did it for a few years but due to time it fell by the wayside.

so our company has invested in a new pat testing machine to test lamps/fridges/ect the machine is a megger pat 150R,

now when i used to test lamps it was always with incandescent bulbs(ones with filaments) now everything is energy or led.

am i right in saying our pat tester with fail these as there is no continuity ,


just all the lamps i am testing with energy or led bulbs are failing.

can somebody point me in the right direction i did question our company whether im still covered for pat testing as i did my course so long ago they said there is no legal requirement to do so im based in the UK.

Thanks in advance

What do you mean by failed continuity.

What do you mean by failed continuity.

Ive attached a video its a leak test if im correct ive tried it on unpainted metal section too. It seems to fail all our lamps on this could it be im using led bulbs/ energy savers

thanks

Are these Class II.

Are these Class II.

Yes

If I'm understanding that unit correctly, that flashing switch icon means that appliance itself it not switched on or is failing open circuit - Is it switched on? The failed test appears to be insulation (R Ins Iso), not Continuity so a plausible failure of insulation on that class 2 item?

i dont know if im wrong in thinking this i believe its because its a energy saving bulb and not creating a closed circuit so to speak like a filament bulb would create .

 

[westward10]

So is it actually switched on during the test.

yeah lamp is switched on

What happens if you don't connect the wander lead.

 

[STUMANN73]

What happens if you don't connect the wander lead.

does exactly to same ive tried 2 different leads just incase

 

[westward10]

Have you tried it with a tungsten lamp.

 

[STUMANN73]

Have you tried it with a tungsten lamp.

Do you mean bulb with actual filament (incandescent) ? No cause we don't sell them. I'm not sure if they are actually banned now in UK

 

[westward10]

Yes that is what I mean. Are these just standard lamp holders if so is it possible to short across the terminals.

Advice if you havn't already got one , get o copy of the CoP for ISITEE. " In Service Inspection and Testing of Electrical Equipment"

That isn't going to resolve the situation.

Yeah standard screw in fittings

Not sure how the tester will see it if the terminals of the lamp holder bridged out but you could try it as this will create a closed circuit.

The lightmate style adapters work good for that
