Under operating conditions, the secondary of a current transformer is ...
The secondary side of the current transformer is always kept short-circuited in order to avoid core saturation and high voltage induction so that the current transformer can be used to measure high values of currents.
  • Current transformer works on the principle of shorted secondary
  • It means that the burden on the system Zb is equal to 0
  • Thus, the current transformer produces a current in its secondary which is proportional to the current in its primary

Understanding Current Transformers
Current transformers (CTs) are essential components in electrical engineering, used to measure alternating current (AC). They work by producing a reduced current that is proportional to the current flowing in the primary circuit.
Importance of Short-Circuiting the Secondary
When operating a current transformer, the secondary side is always short-circuited for several critical reasons:
Core Saturation Prevention
- Avoiding Core Saturation: If the secondary winding is open-circuited, the current transformer will not have a proper path for the current to flow. This can lead to excessive magnetic flux in the core, causing it to saturate. A saturated core cannot accurately transform the primary current, leading to measurement errors.
High Voltage Induction Prevention
- High Voltage Risks: An open secondary can result in very high voltages being induced in the secondary winding due to the lack of load. This high voltage can be dangerous, potentially damaging the CT and creating safety hazards.
Protection of Primary Circuits
- Protection Mechanism: Short-circuiting the secondary ensures that the primary circuit remains protected from high voltage, which could occur if the secondary is left open.
Safety Considerations
- Safety for Human Beings: While short-circuiting the secondary does enhance safety by preventing high voltage, it primarily serves to protect the CT and maintain accurate measurements.
In summary, short-circuiting the secondary of a current transformer is crucial to avoid core saturation and high voltage induction, ensuring accurate current measurement and protecting both the device and the electrical system.
