Customer plant visit

Yesterday I visit at Metaplus Corporation distributor of any kinds of plastic
from national to international. On site Metaplus existing Solo transformer are
3-100 kva and 3-250 kva 3 phase line and he needs to improve his power to
3-500 kva not including the 3-100 kva, from my point of view as per company
standart it needs a primary metering so I just gave him the proposed design
for primary metering which includes the primary construction of the line.
