Form 10S (Form 9S application)
3 phase, 4 wire wye, 3 CTs, 0 or 3 PTs
Does not strictly conform to the traditional Form 10S
wiring. It is intended for most 10S applications. One side
of each voltage section is wired common within the meter.
This wiring restricts the use of phase shifting trans-
formers to perform reactive measurement. If attempted,
equipment damage can occur.
