EC&I Discipline
Electrical = Power Distribution (LV only in-house – 3 phase 400volts a phase) HV – 3rd party – 11,000volts
Instrumentation = Method of monitoring & measuring – wiring back to a control method.
Control = Method of controlling – Field > MCC > PLC > DCS[/vc_column_text][vc_empty_space][/vc_column][/vc_row]
