Nope. The rise/falls are far too fast for anything connected to the grid even if in the same house. If the thing is on the output of a UPS with a rapidly switched load, maybe.
Any big loads, even ohmic heaters, have some inductance. I don't see any such influence. Try an oscillator. I suggested an HP 200 series because they have big output, comparable to the line. Furthermore, it's impossible for such a unit to produce an output step, if it's working right. And they are very cheap. A simple phase shift oscillator with one transistor would work also. I's not use anything digital, like a DDS.
