Polarity of current transformers used in relay protection

The ANSI/IEEE standard for transformers states that the high voltage should lead the low voltage by 30° with wye–delta or delta–wye banks. The connections for these two cases are shown. Polarity is very important for the operation of transformers and protection equipment. Just as water flows from high pressure to low pressure, electrical current flows in a specific direction. How are current transformers used in protection systems for power grids and substations? Current transformers (CTs) are the primary sensing interfaces between high-current power circuits and the low-voltage protection and metering equipment used in substations and transmission networks. It is often marked by square markings or P1 and P2. What is an Internal Fault? What is an External Fault? They step down high primary currents to standard secondary values which is typically 1 A or 5 A enabling relay and metering.
