3 phase meters are "normal" ANSI sized.. For high voltage and high
amperage locations they have current transformers (induction coils)
that factor what the meter sees. ie: a standard meter (US ANSI)
is 200 amps. Put some 2000:1 CT's on it and it's a 400kamp meter.
Note: A US Ansi meter is a big round can, even though the modern
electronics for a 200 amp meter fit in something the size of a circuit
breaker.
