It means DONT GO NEAR IT! (2,700 VAC)
If you can envision a white ball of light enveloping your body as portions of it vaporize and 3rd degree burns if you live - thats what it is. Well, maybe not that extreme - but it will killify you! Voltages of that range and above should only ever be approached by trained and qualified personel - you aint one of them....
KVA: Kilo Volt-Amperes
Ref:
https://www.electrical-contractor.net/ubb/Forum15/HTML/000089.html Kilo = thousand, so multiply the number X's 1000
Volt-Amperes is a referance to a formula for power (watts), and mitigated by power factor, and phase relationship.
Ref:
http://www.abrconsulting.com/Conversions/elec-con.htm#Volt-Amps Ignoring the Power Factor that roughly a million
watts of power. (1000X1000) A mega-watt.
VAC as in 2700 VAC would be 2.7KV or 2700
Volts in an
AC system. (all voltages can be harmfull - and 277 and above,
and this one is far above, can be deadly. Not user friendly...) The box you saw may or may not have that voltage in it, but don't try to find out.... But probhably in the nieghborhood of 2000+, or 2Kv.
Anyway, it was probhably coming from the transmission yard outside.
And the capacitors were probhably, as you guessed, for power factor correction.
