A current transformer is an essential component in modern electrical
installations. It steps down high mains current a level safe
for measuring instruments.
Advantages:
• Current scaling: The device precisely reduces the current
flowing in the circuit to levels acceptable for standard meters
and counters. This eliminates the need to invest in expensive
equipment designed for high loads.
• The current transformer acts as a protective barrier. It provides
galvanic isolation between the high-voltage network and
sensitive measuring devices, as well as operating personnel,
thereby minimizing the risk of electric shock and equipment
damage.
• Reliable network protection: Data supplied by the current
transformer enables protection systems to quickly detect and
respond to hazardous conditions, such as:
- System overloads
- Short circuits in the network
