What does it mean when there is voltage between ground and neutral (220V) and between phase and neutral (220V) but no voltage between phase and ground (0V)?

What could happen? Is it safe?

Is it normal that when I plug in a lamp, it works just fine?


Question: Passenger Name - Flight Booking Passenger only have First Name in Passport
Answer: I called two persons who work for Saudia (ticketing agents), they both said adding the first name in both fields should work, one of them said he would add "MR" as the first name and then add the only name as the last name, either way it should work.  

They also mentioned there is no clear policy regarding this and it might be confusing for people, but once the passport is found with one name people usually accept any of the solutions above. So no worries, you will be fine.
