I was just wondering what this triangle Δ stands for in electronics? e.g. ΔV = 0

The triangle is the Greek letter "Delta." It represents change. For example, if voltage changes from 3V to 5V, the $\Delta$V is 2.

Without wanting to complicate things, you may also come across the letter d used in these terms, as in dV = 0, and its meaning is as thingmaker3 describes above.

Depending on who you speak to, d should be used with respect to another variable, for example dV/dt = 0, means change in voltage in a particular (with respect to) time. Just be aware of the subtleties.
