Gap in conduit running to electric meter
Don't sweat it. 

Wires that are used underground are pretty tough, and are well waterproofed, if water gets in there no harm will be done.

the cable run to the meter is usually maintained by the electricity supplier, so you could contact them for assistance but they will probably not do much.

I see a wide bit and a narrow bit pf conduit, if you line them up the wide bit might slide down to cover the gap.

there's a chance that the conduit might crack when you try to bend it. it depends how old it is. if that hapens call the power company.

if you want an easy  DIY fix slit a piece of PVC tube or conduit so you can clip it over the gap and fasten it with hose clamps.  this won't be waterproof but it will keep fingers out.
