System Using Current Transformers
Figure 28 shows a poly-phase system using four current transformers to support optional Neutral current
sensing for anti-tamper purposes. The Neutral current sensing CT can be omitted if Neutral current
sensing is not required. The system is referenced to Neutral (i.e., the Neutral rail is tied to V3P3A and
V3P3SYS).
