When, while and as can be used as conjunctions of time. They all mean “during the time that ...”.
When a shorter action happened at the same time as a longer action, we use the past continuous tense for the longer action and the simple past tense for the shorter action.
Presentation
When there are two long actions, we often use while.
If the shorter action is in the main clause, we can use when, while or as to join the clauses.
If the longer action is in the main clause, we often use when to join the clauses.

Production
At 7:00 p.m. last Sunday, there was a sudden power cut in my town.
Each member of my family was doing different things at that time, and the power cut affected us in many ways. My mother was cooking in the kitchen when the whole house had a power cut. Therefore, we had to eat some bread and fruit. My father was writing an important report in the study. He had to write it later. I was taking a shower at that time. I had no choice but to put on my clothes in the dark.
From then on, we realized the importance of electricity in our daily lives.
