There is a second entrance, which you can access from the pantry. Go to the very bottom of the stairs, and look for a button, just to the left of a suspiciously empty bit of wall.

Do you already have the vault key?

Also, ... you know for every single one of those devices, there's a way to disable them. You need to look around.

This. It solves your problem here even without the second entrance.

The specific arc pylon Blazsword is referring to here is directly outside the vault entrance. Both the security panel, AND whale oil unit are in full view of the Pylon.

Aside from finding an alternative way into the vault (Of which there are two. Hint #1: Anton gives you a big tip before the mission, #2 take a dip in rune water), you can try:

1) Blinking / Far reaching directly next to the whale oil container. If the arc hasn't wound up yet, you should have just enough time to pull it out before the arc zaps you.
2) Summoning Rat Swarms / Dopplegangers next to the Pylon to exhaust it's supply of whale oil. This can be resource intensive, but it works.
3) For Corvo, slowing down time to make #1 easier, or possessing someone to then take out the power supply.

Yup that's all I had to do, your number 1. A touch harder with no-powers, but at that run I just went through the other direction and avoided it entirely.
