Wrong answer.  "BIL" stands for "basic impulse level."  BIL
is a specification that applies to power line transformers,
insulators, switchgear; almost anything that handles high
voltages in the power industry.  Typically, a Marx Impulse
generator is configured to deliver a certain impulse waveform
with a short rise time (say 5 usecs.) and a wave tail or
decrement (say 40 to 200 usecs.)  This waveform conforms
to established IEEE standards, to either simulate a lightning
discharge or a switching surge.  The insulation level of
the specimen being subjected to the impulse, must be able
to withstand the crest voltages, delivered by the impulse
generator, with no failure of the insulation.

Base (or basic?) insulation level???
