Definition
A current transformer, commonly referred to as a CT or torus, is an electrical component throughwhich a cable can be passed.
The function of these CTs is to reduce the value of the current passing through them (primary) to a lower value (secondary).
What types of CTs are available?
There are different types of CTs; they can be closed (loop or through) or split-core. Split-core current transformers can be rigid or flexible (Rogowski coils).
What are CTs connected to?
In most cases, CTs are connected to measuring devices (energy meters or measuring stations), indicators (digital or analogue), capacitor banks or converters.
Which products are suitable?
Our solutions enable primary currents of up to 8,000 A to be reduced to a secondary current of 5 A, 1 A (for petrochemical applications) or 333 mV. We also offer current transformers with secondaries adapted to the process signal (4-20 mA, 0-10 V) and Modbus.
