Current Transformer Through Bar - 250/5a Tab2

The technical description you provided is for a current transformer with a through-bar, which is primarily used for measuring current in an electrical system. Here are the technical details based on your description:

• Transformer Type: Current Transformer with Through Bar
• Transformation Ratio: 250/5A
  • 250A : Primary current (the current measured in the main circuit).
  • 5A : Secondary current (the reduced current, which is sent to measuring instruments or protective devices).
• Model: Tab2 (May indicate a specific manufacturer series or model)

Additional details:

• Main Use: This type of transformer is used to reduce the high current of a circuit to a lower, safe level, suitable for measurement or monitoring by instruments such as ammeters or protection relays.
• Installation: Usually mounted in electrical panels, where the cable carrying the main current passes through the transformer bar.
• Accuracy: Current transformers are designed to provide a precise transformation ratio, which is critical for accurate current measurements.
